BETA 200 S LED Ophthalmoscope head 2.5 V without handle

The dustproof design protects the precision optics and enables maintenance-free use. The BETA 200S LED ophthalmoscope is the only one with an aluminium support element. The optical components are integrated flush into a cast aluminium frame, which prevents decentration and makes the instrument resistant to shocks.
- The BETA 200S LED ophthalmoscope has a Rekoss disc with 28 individual lenses, which prevents higher refraction deviations, 74 one-dioptre steps on the non-continuous lens wheel prevent extreme dioptre jumps
- any dioptre value from -36 to +38 dpt can be set in 74 one-dioptre steps
- LED in HQ: the LED illumination is precisely matched to the optical system and provides very bright and uniform illumination in combination - for reliable diagnosis
- LED with practically unlimited service life, no need to change the bulb
- Aspherical Optical System (AOS): eliminates light reflections, optimises the usable illumination on the back of the eye and thus ensures a uniquely large, bright and high-contrast retinal image
- patented and unique infinitely variable dimming between 3 - 100 % with practical one-finger operation
- no stray light thanks to the recessed, multi-coated viewing window - for reliable diagnosis
- Can be used for both dilated and non-dilated pupils
- the ergonomic shape adapts comfortably to the orbit and shields the surrounding light
- for all BETA handles 2.5 V with automatic lock
- 7 luminous field diaphragms with separately switchable interference red-free filter
- Apertures: Slit, fixation star with polar coordinates, blue filter, large circle, medium circle, semicircle, MicroSpot
