Division of beams of lighting and supervision by means of aspherical optical system cancels a lid reflex. BETA 200 allows you to see a full picture on the lit retina site even through a small pupil. While ordinary ophtalmoscopes allow you to see only part from the lit site.
The BETA - 200 ophtalmoscope - one of the most ergonomic! Well thought over arrangement of disks of diaphragms, them \ "tenacious \ " a nakatka, comfortable illumination of values of a Recoss - disk do the device extremely convenient in work.
Wide functionality is defined by the following characteristics of an oftalmoskopichesky head:
- Quantity of corrective lenses: 27.
- Range of corrective lenses, dptr from: - 37 to + 25.
- Diaphragms for average, normal and expanded pupils, a fixating and measuring grid (a star with polar coordinates), the cobalt blue filter, a crack.
- Survey without lid reflex. The complete overview is guaranteed even at a small pupil.
- The galogenovy bulb gives to HEINE XHL bright, this world.
- The profound, multilayer observation port gives the chance to avoid dispersion of light.
- The dustproof body does not demand service.
- Soft plastic around an observation port protects points of the user.
- The picked - up range of lenses yields good results of inspection even with high disturbances of a refraction.
The ophtalmoscope with unique aspherical optics and total characteristics of BETA 200S, except for an aperture "point" and the following number of dioptric lenses:
+ step to 1 dioptry: 1–10 15 20 40 dioptries
– step to 1 dioptry: 1–10 15 20 25 30
