Wall Mounted Format
The instrument is described as mounted on the wall, keeping it within reach of the examination chair while leaving the working surface below entirely clear.
Five Illumination Forms
Large spot, small spot, slit, net and red free are all listed, described by the manufacturer as meeting various observation requirements without additional accessories.
Slit Beam
A narrow band of light is included among the forms. The way a slit deforms as it crosses the retinal surface assists in judging elevation and contour.
Net Graticule
The net introduces a grid into the observed field, which helps the examiner estimate the position and relative size of a feature rather than describing it loosely.
Red Free Setting
Removing red from the beam darkens the vessels against the retina behind them, giving a clearer view of vascular detail and the nerve fibre layer.
Compensation Across 24 Steps
Dioptre compensation spans minus 35D to plus 20D in 24 steps in total, reaching high myopia at one end and hypermetropic eyes at the other.
Halogen Illumination
The source is a halogen bulb rated at 3.5V and 2.8W, related by the manufacturer to a high colour temperature, good colour rendering, an even light spot and a sharp image.
Soft Start and Automatic Turn Off
Soft starting and an automatic turn off function are described as extending the service life of the bulb, with soft rubber around the eyeholes protecting and steadying the instrument.
