HEINE Beta 200 S Ophthalmoscope head without handle

The dustproof design protects the precision optics and enables maintenance-free use. The BETA 200 S ophthalmoscope features an aluminium support element. The optical components are integrated flush into a die-cast aluminium frame, preventing decentration and making the instrument resistant to knocks. The BETA 200 S LED has an LED with a virtually unlimited service life (up to 100,000 hours), no lamp replacement required. - HEINE’s “Aspherical Optical System” (AOS) eliminates light reflections, optimises the usable illumination on the fundus and thus provides a large, bright, high-contrast retinal image. - the standard in LED illumination delivers absolutely homogeneous and bright light with true colour rendition for precise diagnosis. Red is red, blue is blue. Colour temperature 3500 K, colour rendering index (CRI) >97, especially for red tones (R9) >93 with a scale maximum of 100 - the LED illumination is precisely matched to the optical system and, in combination, delivers very bright and even illumination for reliable diagnosis - the BETA 200 S ophthalmoscope has a Rekoss disc with 28 individual lenses that prevents higher refractive deviations; 74 one-dioptre steps on the non-continuous lens wheel avoid extreme dioptre jumps - 7 apertures (blue filter, fixation star with polar coordinates, large circle, medium circle, MicroSpot, slit, semicircle) with separately switchable interference red-free filter - continuous brightness control between 100% and 3% with single-finger operation - no stray light thanks to the recessed, multi-coated viewing window - precise one-handed operation of the instrument: the ergonomic design offers flexibility during examination - suitable for both dilated and non-dilated pupils - the ergonomic shape fits comfortably to the orbit and shields ambient light - full functionality of the BETA 200 S LED is ensured with the current BETA rechargeable handles and the EN 100 wall unit
