- Unique optical system. HEINE ideally optimizes the Gullstrand principle (separation of illumination and observation beams). Reflections of the cornea and iris are eliminated. Even with pupils in miosis, there is a wide view of the retina.
- Xenon XHL halogen technology. High light intensity.
- Observation window applied in depth. Reduces side light interference.
- Hermetically sealed structure. Minimal maintenance.
- Optical parts mounted on a metal supporting structure. Long service life and consistent optical accuracy.
-Ergonomic. The instrument easily adapts to orbital contact.
- Soft orbital support. Protects the examiner's glasses, stabilizes the instrument.
- 7 diaphragms with green filter (red absorbent) that can be inserted into the light beam (see drawing). Suitable for dilated and miosis pupils. Include slit diaphragm, fixation star, cobalt blue filter and green filter for greater contrast. It also has a "microspot" for the macula.
- Correction range: Perfect focus even in the case of strong refractive errors.
