Which ENT microscope do I need?

Updated · Labo America product team
THE SHORT ANSWER

Most ENT offices need a microscope for ear examination and cleaning that is quick to position and bright. The Prima Lite ENT does that with a 90 degree straight binocular tube, a 5 step apochromatic changer and a 27 W LED built into the head. Residency and skills labs use the Prima Trainer. For procedures that need more room, the Prima Lite ENT takes f300 and f400 objectives and NuVar variable objectives.

What should I look for in an ENT microscope?

Look at five things: the viewing tube, the objective focal length, the light, how it mounts in your room, and whether you can add a camera or endoscope. The Prima Lite ENT has a 90 degree straight binocular tube, a 5 step apochromatic changer (0.4x to 2.5x), an f250 objective with fine focus, a SuperLux 27 W LED integrated in the housing, and floor, wall and ceiling versions.

Which objective focal length suits ENT work?

Focal length sets how far the microscope sits from the patient. Shorter distances suit ear examination close to the patient. Longer focal lengths leave room for long instruments, which is why 300 mm and 400 mm objectives are common in laryngeal work. The Prima Lite ENT ships with f250 and offers f200, f300 and f400 objectives, plus NuVar 7 (200 to 270 mm working distance) and NuVar 10 (300 to 400 mm focal length) variable objectives.

Why do ENT microscopes use a straight binocular tube?

For ear examination you usually look horizontally across to the patient's ear, and a straight tube puts the eyepieces in line with that view. The Prima Lite ENT uses a 90 degree straight binocular tube with an interpupillary range of 49 to 78 mm.

Can I connect an endoscope to my ENT microscope?

Yes. The Prima Lite ENT offers an endoscope camera adapter that works with the DBS 50:50 beam splitter.

Can I record ENT procedures for patients and teaching?

Yes. A beam splitter sends part of the light to a camera while you keep looking through the eyepieces. The Prima Lite ENT accepts C-mount, DSLR and smartphone adapters and the Atlas+ 4K camera, and a VESA arm can hold a monitor.

What is the difference between an office ENT microscope and an operating room microscope?

An office microscope prioritizes fast positioning, bright light and a small footprint. An operating room microscope adds motorized control so the surgeon can change magnification and focus without taking hands off the instruments. For procedures that need more working distance, the Prima Lite ENT takes f300 and f400 objectives and NuVar variable objectives.

What microscope should an ENT residency or skills lab buy?

Buy optics that match what residents will use in clinic, on a mount that fits the lab bench. The Prima Trainer uses the 5 step apochromatic changer from 0.4x to 2.5x, a 50 W LED rated at 125,000 lux, a 0 to 210 degree tilting head and a table mount with C-clamp. It is also listed for ENT training on our range.

How much does an ENT microscope cost and what warranty comes with it?

Cost depends on the mount, objective, documentation and accessories you choose, so dealers quote the configuration. Build yours in the configurator and request a quote. LABOMED® medical products carry 2 years on parts and labor, 2 years on cameras and 1 year on electrical parts, with lifetime cover available as an optional add-on.
