HEINE BETA 200S LED Ophthalmic Diagnostic Set: BETA 200S LED Ophthalmoscope, BETA 200 Streak Retinoscope, BETA4 NT Rechargeable Handle, NT4 Table Charger, Hard Case. MFID: C-262.24.420

• Reliable Diagnosis: Clear, bright and non-reflective image due to AOS (Aspherical Optical System). ♦ Lens | Diopter: 28 lens | 74 single-diopter steps (-36 D to +38 D). ♦ Apertures: 7 luminous field apertures with separate red-free filter: cobalt blue filter, fixation star with polar coordinates, large spot, small spot, pinhole, slit, hemispot. ♦ No light reflections, since the illumination beam and the observation path are separate. ♦ The instrument head fits precisely to the eye socket, blocking out ambient light. ♦ Can be used for both dilated and non-dilated or particularly small pupils due to the pinhole aperture.
• Optimum Illumination: Patented and exclusive continuous dimmability between 3 and 100%. ♦ No stray light thanks to the recessed, multi-coated viewing window. ♦ Helpful when examining cloudy lenses, as LEDHQ provides particularly bright illumination.
• Exceptional Durability: Maintenance-free use due to dustproof design. ♦ Impact-resistant due to a cast aluminum frame that the optical components are embedded in. ♦ No need to ever exchange the LED thanks to LEDHQ.
• Easy to Use: Instrument can be operated with one hand. ♦ Flexibility during the examination due to the ergonomic design.

• Reliable Diagnosis: Reliable measurement of the eye's refraction ♦ Precise adjustment of the parallel beam path due to ParaStop ♦ Very bright and clearly visible fundus reflex due to a very bright, precise streak with a line width of typically 1.1 mm (ISO 12865 standard < 1.5 mm) and a line length of 35 mm ♦ Particularly bright and even light due to LEDHQ ♦ Patented and exclusive continuous dimmability between 3 and 100% ♦ Polarization filter eliminates stray light and internal reflections ♦ Minimized light leaks due to good eye socket coverage
• Enhanced Durability: Exceptional durability due to metal controls ♦ Maintenance-free and dustproof ♦ LEDHQ with virtually unlimited working life
• intuitive Operability: Practical one-finger operation ♦ Convenient thumb operation with a single control for vergence and line rotation
