290 mm × 332 mm × 700 mm (312 mm × 305 mm × 700 mm in some sources).

Net Weight: 11.4 kg (without power supply, headrest, or optional accessories).

Applications:

Ideal for general ophthalmologists and optometrists for examining anterior and posterior segments.

Suitable for contact lens fitting, tonometry (glaucoma diagnosis), and detailed visualization of cornea, iris, lens, and retina.

Supports high-quality imaging for documentation and analysis, particularly with the Fundus Module 300.

Notes:

The BM 900 is renowned for its optical excellence, bright illumination, and durability, with over 100,000 units used globally by eye care professionals.LED illumination eliminates the need for frequent bulb replacements, unlike older tungsten models, reducing maintenance costs.The slit lamp is designed for clinical settings and is not portable.
