- Unique optical system. HEINE ideally optimizes the Gullstrand principle (separation of illumination and observation rays). Corneal and iris reflections are eliminated. A wide view of the retina is obtained even with miotic pupils.
- XHL Xenon halogen technology. High light intensity.
- Deep-set viewing window. Reduces interference from lateral light.
- Hermetically sealed construction. Minimal maintenance.
- Optical components mounted on a metal support frame. Long service life and consistent optical precision.
- Ergonomic. The instrument easily adapts to orbital contact.
- Soft orbital support. Protects the examiner’s glasses and stabilizes the instrument.
- 7 apertures with a green filter (red-absorbing) that can be inserted into the light beam (see drawing). Suitable for dilated and miotic pupils. Includes a slit aperture, fixation star, cobalt blue filter and green filter for greater contrast. Also features a “microspot” for the macula.
- Correction range: Perfect focusing even in cases of significant refractive errors.

74 individual corrective lenses:
+ in single values: from + 1 to + 38
- in single values: from - 1 to - 36
