Visionstar SLT

Two Magnifications

Both 2.5x and 3.0x are available. The choice sets not only how large the view appears but also how much of the field remains visible at any given distance, so the two choices have to be made together.

Four Working Distances

Each magnification is listed at 340mm, 420mm, 460mm and 500mm, so the pair can be matched to how the wearer actually sits relative to the patient.

Field of View at 2.5x

The field runs 60mm at 340mm, 70mm at 420mm, 80mm at 460mm and 95mm at 500mm, widening steadily as working distance increases.

Field of View at 3.0x

The field runs 40mm at 340mm, 46mm at 420mm, 50mm at 460mm and 54mm at 500mm, narrower throughout than the lower magnification at the same distances.

Custom Fit and Working Distance

The manufacturer describes both custom fit and custom working distance, so the pair is built around the individual wearer rather than chosen from fixed sizes.

Multi Coated Anti Reflective Lenses

All lenses are described as multi coated and anti reflective, which reduces stray reflection across the optical surfaces the light has to pass through.

Infinity Corrected Optics

The coatings are described as combining with an infinity corrected optical system, alongside precision optics and high resolution.

Lightweight Construction

Weight is listed as little as 2 oz, around 57g, including the frame, which is what makes wearing them across a full clinical list realistic instead of merely possible for short periods.

Restorative and Fine Dental Work

Margins, preparation edges and fissure detail are the work that magnification most obviously improves, because the structures being judged sit at the limit of what the unaided eye resolves. At 2.5x with a 500mm working distance the field is 95mm, wide enough to keep the quadrant in view, while 3.0x concentrates on a smaller area. Which suits a given practitioner depends on their technique and how they prefer to work.

Surgical and Ophthalmic Procedures

Any procedure where the operative field is measured in millimetres benefits from magnification worn rather than positioned, since the view follows the head automatically. The infinity corrected optical system and multi coated lenses are what keep the image usable at these powers. A narrower field at 3.0x is the trade for the additional detail, which is why the working distance chosen matters as much as the power.

Working Posture Over a Long Day

Working distance determines how far a clinician sits from the patient, and therefore how far they lean. A pair built to a custom working distance lets the wearer stay upright and still see clearly, where an unaided view would pull them forward. Over the years of a career, the cumulative effect on the neck and back is the reason many clinicians adopt loupes at all.

Use Alongside Illumination

Magnification narrows the field and increases the light needed within it, so loupes and a worn light are commonly used together, mounted on the same frame. Whether a particular light and mounting arrangement suits these loupes is a practical question worth settling in advance with Medigear.uk rather than after the pair has been built.

Built to the Wearer

Custom fit and custom working distance mean the pair is made for one clinician rather than adjusted toward them. Loupes bought off a shelf are a compromise on interpupillary distance, declination angle and working distance at once, and a compromise on any of those shows up as fatigue rather than as blurred vision. Something built to the individual is worn all day; something approximate ends up in a drawer.

A Specification You Can Choose From

Eight combinations are listed across two magnifications and four working distances, with the field of view stated for every one. That lets a practitioner reason about the trade directly, since a 40mm field at 3.0x and 340mm is a very different working experience from 95mm at 2.5x and 500mm. Published figures for each combination make the choice an informed one rather than a matter of trying and hoping.

Light Enough to Forget

At around 57g including the frame, the load on the nose and ears stays small. Weight is the single factor that decides whether magnification is worn continuously or only for the difficult part of a procedure, and intermittent use gives away most of the benefit. Multi coated anti reflective lenses within an infinity corrected system then keep the view comfortable through extended wear.

The Visionstar SLT loupes are specified plainly. Two magnifications of 2.5x and 3.0x are offered across working distances of 340mm, 420mm, 460mm and 500mm, with field of view stated for every combination, running from 40mm at 3.0x and 340mm up to 95mm at 2.5x and 500mm. All lenses are multi coated and anti reflective within an infinity corrected optical system, and weight is listed as little as 2 oz, around 57g, including the frame, with custom fit and custom working distance described by the manufacturer.

This page states what the technical data states. Frame styles and colours, prescription integration, the fitting and measurement process, cases and accessories, configuration and condition do not appear on the material held, and nothing here should be read as a claim about testing or regulatory approval. Medigear.uk will confirm each of those points, along with what is included when a pair is supplied.

If your clinicians are considering magnification, or replacing a pair that never quite suited them, and you want the specification checked against how they actually work, speak to Medigear.uk. As a verified medical equipment supplier working across medical, dental, rehabilitation and aquatic therapy settings, the team will confirm what these loupes offer and how the fitting is arranged.
