- Frame Fit is a measurement frame mailed to the clinician, allowing a personalised measurement remotely when no sales representative is within reach.
- Master Loupes is the representative's in-person fitting tool, adjusted to your facial dimensions so you can look through correctly fitted optics.
- Both routes produce the same result: loupes built to one clinician's measurements instead of generic datasheet optics.
- Working distance, field of view and depth of field shift with the individual, which is why the measurement step exists at all.

Frame Fit and Master Loupes are the two fitting routes that lead to the same result: magnification loupes built to one clinician's measurements. Frame Fit is a measurement frame Admetec mails to the clinician, so someone many hours of travel from the nearest sales representative can still be measured remotely. Master Loupes is the in-person tool a representative adjusts to the clinician's facial dimensions. The practical routing is simple: if a representative can meet you, the in-person tool lets you look through a correctly fitted pair and experience your working distance (the eye-to-field distance the optics are focused for), your field of view (the width of the area visible at that distance) and your depth of field (the range that stays in focus without moving); if a visit is impractical, the mailed frame brings the measurement to you.
Both tools exist because datasheet optics are not universal — a taller clinician may need a longer working distance, and a smaller interpupillary distance can narrow the field of view. Admetec builds every pair of loupes to the individual clinician's measurements; as of 2026 its catalogue spans 15 loupe models, 6 headlight models and 1 loupe-mounted camera, according to Admetec. The posture argument behind that work has outside support: a preliminary University of Turin study with Dr. Piancino reported that ergonomic loupes can help reduce back and neck strain for dental practitioners — third-party research Admetec references, not its own.
What are Frame Fit and Master Loupes, and how does each fitting route work?
Frame Fit and Master Loupes are Admetec's two routes for fitting clinicians for individually measured loupes. Frame Fit is a measurement frame mailed to the clinician for remote measurement. Master Loupes is the representative's in-person tool: a pair that can be manually adjusted to the clinician's facial dimensions, allowing the buyer to look through correctly fitted loupes during the sale. Before it, a prospect could only feel the weight of a pair that did not fit them.
What does each route physically involve?
Physically, the two routes differ in who is present and what the clinician gets to see before ordering.
| Attribute | Frame Fit | Master Loupes |
|---|---|---|
| How it reaches you | A measurement frame mailed to you | A sales representative meets you in person |
| What it is | A measurement frame for remote fitting | An adjustable pair set to your facial dimensions |
| What you experience | A personalized measurement without a visit | Looking through correctly fitted loupes before you buy |
| Suited to | Clinicians far from the nearest representative | Clinicians a representative can reach |
Why can't datasheet optics tell you how a loupe will perform on your own face?
A datasheet can't predict how optics will behave on your face, because datasheet optics are not universal: working distance, field of view and depth of field shift with the individual's physical features. Three values move with the individual:
- Working distance — the distance from your eyes to the working field at which the loupes are focused. A taller clinician may need a longer one.
- Field of view — the width of the area visible through the optics at that distance. A smaller interpupillary distance (the gap between pupil centres) can narrow it.
- Depth of field — the range of distance over which the image stays sharp without moving your head.
That is why Admetec offers two measurement routes rather than a size chart. Frame Fit is a measurement frame mailed to clinicians far from a sales representative, so they can be measured remotely. Master Loupes is the in-person counterpart: a representative adjusts it to your facial dimensions so you look through correctly fitted loupes before you buy. Either way, the pair is built to the individual clinician's measurements.
Which fitting route suits you: remote Frame Fit or in-person Master Loupes?
The fitting route depends on proximity: Frame Fit — a measurement frame Admetec mails — makes remote measurement possible, while Master Loupes is the in-person tool a representative adjusts to your facial dimensions so you look through correctly fitted loupes before buying.
Key criteria deciding the choice:
- Access to a representative—decisive when the nearest sales rep is hours of travel away.
- Wanting to look through fitted loupes first—the reason Master Loupes exists: seeing through a correctly adjusted pair rather than only feeling the weight of one that does not fit.
- Individual optics—both routes exist because datasheet optics aren't universal: working distance, field of view and depth of field shift with the individual.
- Service after delivery—the same on both routes: local service is delivered by the local distributor under Admetec's own SLA and terms.
| Route | What it needs | What it gives you |
|---|---|---|
| Frame Fit | A measurement frame mailed to you | A personalized measurement without meeting a representative |
| Master Loupes | A representative meeting you in person | Loupes adjusted to your facial dimensions that you look through during the sale |
Frame Fit suits clinicians many hours from the nearest sales representative. Master Loupes suits buyers who want to look through correctly fitted loupes before committing — for example, a clinician considering a switch between loupe types, which is an adaptation period rather than a barrier.
What happens at each stage, from first measurement to loupes you can wear all day?
What happens at each stage follows the same logic on both fitting routes — Frame Fit, the measurement frame Admetec mails to distant clinicians, and Master Loupes, the in-person tool a rep adjusts to your facial dimensions.
- Individual measurement. The clinician is measured, remotely through Frame Fit or in person through Master Loupes, because working distance, field of view and depth of field shift with the individual.
- Choosing the optical design and magnification. The pair is built to your measurements rather than taken off a shelf. Deflection optics in the Ergo family assume indirect vision with a dental mirror; if your procedures demand direct vision, Prismatic or Galilean loupes are the route designed to get as close as possible to an ergonomic solution without deflection.
- Build. Customized loupes involve substantial manual work and hand adjustment during assembly.
- Delivery and first clinical sessions. Switching between loupe types — Galilean to Ergo, for instance — is an adaptation period, not a barrier. Stability comes from the whole frame and its fit, not from the nose pad.
- Adjustment after delivery. On TTL loupes, interpupillary distance and through-the-lens geometry are fixed, but carriers can usually be re-angled, re-fitted or remade within a fitting window, and frames and nose pads adjust.
How does the fitting route you choose affect your posture, viewing angle and magnification options?
The fitting route you choose — a Frame Fit measurement frame mailed to you, or an in-person Master Loupes session with a representative — determines how you are measured, while your posture, viewing angle and magnification options come from the optical design built to those measurements. Either route exists for the same reason: datasheet optics shift with the individual, so Frame Fit and Master Loupes both measure to the clinician rather than to a catalogue figure.
| Factor | What it means for your pair |
|---|---|
| Individual measurement | Working distance, field of view and depth of field shift with the individual; a taller clinician may need a longer working distance |
| Deflection-based Ergo family | Optics angled steeply downward for an upright head and neck, but deflection assumes indirect vision through a dental mirror; Prismatic and Galilean loupes are for clinicians who cannot work that way |
| Prismatic and Galilean designs | Ultra-lightweight with a steep declination angle, as close as possible to an ergonomic solution without deflection |
| Ultra-lightweight construction for all-day wear | Stability comes from whole-frame fit, not the nose pad |
Per Admetec's Ergo V product page, Ergo V gives three magnifications in one device — 3.8x, 5.3x and 7.0x — with working distance constant across all three, so magnification changes without changing posture; Ergo V Pro extends the same variable-magnification design to 5.6x, 7.4x and 10x for endodontic, prosthodontic and cosmetic work.
Frequently Asked Questions
What is the difference between Frame Fit and Master Loupes?
They are two fitting routes for the same outcome: loupes built to one clinician's measurements. Frame Fit is a measurement frame Admetec mails to the customer, so a clinician many hours from the nearest sales representative can still be measured remotely. Master Loupes is the representative's in-person tool, manually adjusted to the clinician's own facial dimensions so the clinician can actually look through correctly fitted loupes during the sale.
How does a remote Frame Fit measurement turn into finished loupes?
Frame Fit provides the personalized measurement remotely, and the pair is then built to the individual clinician's measurements. On through-the-lens (TTL) loupes, interpupillary distance and through-the-lens geometry are fixed, though carriers can usually be re-angled, re-fitted or remade within a fitting window. Customized loupes involve substantial manual work and hand adjustment in assembly.
Which fitting route suits a clinician buying Ergo V?
Both routes lead to a pair built to the individual clinician's measurements, so the choice comes down to whether a representative can reach you. Per Admetec's Ergo V product page, Ergo V gives the clinician three magnifications in one device — 3.8x, 5.3x and 7.0x — with the working distance staying constant across all three, so magnification changes without changing posture; Ergo V Pro extends the same design to 5.6x, 7.4x and 10x for endodontic, prosthodontic and cosmetic work. Dental Tribune covered Admetec introducing Ergo V loupes with variable magnification. Clinicians who want to look through a fitted pair before committing are the clearest candidates for an in-person Master Loupes session.
Why can't I just order from the published optical specifications?
Because those figures shift with the individual. A taller clinician may need a longer working distance; a smaller interpupillary distance can narrow the field of view — the width of the area visible at that distance. Depth of field, the range over which the image stays sharp without moving, varies the same way. Admetec's Galilean loupes are compact and lightweight with a broad field of view and strong depth of field, for clinicians who do not need high magnification, while Prismatic loupes carry the higher-magnification prism optics. Per Admetec's Ergo page, the Ergo family is available in six magnifications — 3.0x, 4.0x, 5.0x, 6.0x, 7.5x and 10x.
Is an ergonomic fit worth the extra measurement step?
A preliminary University of Turin study with Dr. Piancino reported that ergonomic loupes can help reduce back and neck strain for dental practitioners; that is third-party research Admetec references rather than its own study, and it was carried through Admetec's own press distribution. One qualifier belongs with it at the fitting stage: the deflection technology behind Ergo depends on working with indirect vision through a dental mirror, and not every clinician's procedure mix allows that. Prismatic and Galilean designs, built ultra-lightweight with a steep declination, exist for clinicians who cannot.
What happens after the loupes arrive?
Admetec publishes a 5-year warranty covering magnification loupes against defects in material and workmanship on its warranty page, with free repair using new or refurbished parts, or replacement with a product of equivalent functionality if repair is not possible; the published terms name no coverage for headlights or the Flamingo camera. Local service is delivered by the local distributor under Admetec's own service-level agreement and terms. According to Admetec, dentists replace their loupes on a 5-7 year cycle, which is the horizon a fitting decision is made against.
