Coaxial ophthalmoscope

A coaxial ophthalmoscope is a medical device used to examine the internal structures of the eye, the retina, and the optic nerve. This device has a number of optical and electrical characteristics that make it an indispensable tool in ophthalmological practice.

One of the key features of the coaxial ophthalmoscope is the presence of a red-free filter, which allows you to reduce glare and improve the visibility of the vessels and tissues of the eye. The ophthalmoscope is equipped with different types of apertures for different tasks. A large aperture is used to examine large areas of the retina, a small aperture allows for a detailed examination of small areas, a hemi aperture (semi-circular light beam) improves peripheral vision, and an aperture with a fixation point helps the patient focus his gaze during the examination.

The coaxial ophthalmoscope is powered by two AA batteries, which can be either alkaline or rechargeable. The choice of bulb type depends on the user's needs: a 2.5 V / 0.5 W LED bulb provides bright, energy-efficient lighting, while a 2.5 V / 1.6 W halogen bulb provides a more natural light, which may be useful in certain clinical cases.

The device has an internal power source to protect against voltage drops, which ensures stable operation. The operating mode of the ophthalmoscope is intermittent: it operates for 2 minutes in the "on" mode, after which it switches to the "off" mode for 5 minutes to prevent overheating and extend the service life of the device.

Due to its unique optical and electrical characteristics, the coaxial ophthalmoscope is an important tool for the diagnosis and treatment of eye diseases, providing high accuracy and reliability in the daily work of ophthalmologists.
