Direct Ophthalmoscopes
In direct ophthalmoscopy, the fundus is examined with the ophthalmoscope at a short distance. Central parts such as the optic nerve head, the origins of the vessels and the yellow spot (macula lutea) can be observed. This process is more detailed with the higher magnification compared to indirect ophthalmoscopy, but therefore only a small part of the fundus can be observed.
Examinations are particularly well performed with instruments from our BETA 200 series with aspheric optics, preferably with LEDHQ, but also the HEINE K180 or both mini 3000 ophthalmoscopes (with LEDHQ or XHL illumination).

The EZ-OPH-3600 uses a combination of 68 focusing lenses with single-diopter steps (+38D to -38D) to provide the operator with precise resolution and premium quality during examination.
18 Unique Aperture and Filter Combinations
This high-end device also contains an extraordinary 18 unique aperture and filter combinations, for greater versatility. Having a diverse amount of filters provides optimum light levels for entering healthy eyes and those with cataracts. This device has essential diagnostic filters including: Cobalt Blue, Cross-linear Polarizing, and Red-free.
- Micro-Spot Aperture: allows quick entry into small, undilated pupils.
- Small Aperture: provides excellent view of fundus through an undilated pupil
- Large Aperture: standard aperture for a dilated pupil and general examination of the eye.
- Fixation Aperture: has graduated cross-hairs for measuring eccentric fixation or locating lesions.
- Slit: used to determine levels of lesions and tumors
- Red-free Filter: excludes red rays from examination field for easy identification of veins, arteries and nerve fibers.
