Colour temperature: 3,500 K, Colour Rendering Index (CRI) > 97, special index for red colours (R9) > 93 on a maximum scale of 100.
• Special optical interface to precisely integrate the LED illumination with the optical system to ensure bright, homogeneous light during examinations.
• Exclusive continuous brightness control between 100 % and 3 % (patent pending) with one-finger operation.
• No stray light due to the recessed, multi-coated viewing window – eliminates distractions.
• Precise one-hand control of the instrument. Ergonomic design offers flexibility while examining.
• Suitable for large, as well as small or undilated pupils.
• Ergonomic design fits the orbita comfortably, and blocks out ambient light.
• Accommodates higher refractive errors with a  28 single lense Rekoss Disc and features a 74 single step design on a non-continuous wheel avoiding extreme diopter jumps. 

Apertures:

HEINE AOS:

“Aspherical Optical System” (AOS) exclusively from HEINE eliminates corneal and iris reflexes to provide large, crisp and glare-free fundus images:

[ 01 ] Flat, elliptical illumination beam produced by HEINE’s patented Aspherical Optical System.

[ 02 ] Observation path.

[ 03 ] Redirected iris and corneal reflexes.

[ 04 ] The elliptical light beam enters through the lower half of the cornea. The illumination beam has been separated from the observation beam (Gullstrand-Principle). All reflexes are diverted away from the observation beam due to the curvature of the reflective cornea. Due to the flat, compressed form of the light beam, a maximum amount of light enters through the pupil.

[ 05 ] Once past the anterior chamber, the light beam opens up dramatically to illuminate a large area of the retina.
