Product view
Built for demanding clinical work.
The BL-99C is our most versatile digital slit lamp. It is designed for eye care professionals who expect an exacting level of optical performance, precise control, and dependable operation from the instrument they use every day. A wide range of optional accessories allows it to support many diagnostic applications while maintaining comfort, versatility, and precision.
Optical excellence
The Galilean microscope provides five magnification steps—6×, 10×, 16×, 25×, and 40×. High light transmission and carefully resolved optics produce a bright, detailed view throughout the magnification range, supporting routine examinations as well as closer evaluation of fine structures.

LED illumination
Every current BOLAN slit lamp uses advanced LED illumination to produce a bright, sharp, and homogeneous slit beam. The long-life LED eliminates routine bulb changes.
A tilting frame supports reliable posterior segment viewing, while the defocusing function expands the available options for indirect illumination. Controls are positioned where they fall naturally to hand, making adjustments smooth, precise, and effortless throughout the examination.

Light filters
The BL-99C includes yellow barrier, cobalt blue, neutral density, and red-free filters.
- Yellow barrier
- The yellow barrier filter improves contrast during fluorescein viewing, helping reveal corneal and tear-film detail.
- Cobalt blue
- Cobalt blue illumination supports the evaluation of epithelial defects, abrasions, corneal ulcers, herpetic lesions, and contact lens fit.
- Red-free
- The red-free filter improves visibility of the retinal nerve fiber layer, making wedge defects easier to identify. It also helps distinguish pigmented lesions from vascular structures and hemorrhages.
Each filter can be engaged or removed quickly using the control lever.
Precision mechanics, effortless control, and enduring performance
The BL-99C is engineered for exceptionally smooth, precise movement, allowing the clinician to position the instrument accurately with minimal effort. Its balanced mechanical design helps reduce wrist and finger strain, even during extended clinical use.
High-grade materials and careful construction keep every movement stable, controlled, and responsive. This supports efficient operation and greater user comfort in demanding clinical environments.
Built to exacting standards, the BL-99C is intended as a long-term investment in quality—designed to maintain its performance and integrity through decades of daily practice.

Integrated digital imaging
The integrated 8-megapixel imaging system captures 3840 × 2160 JPEG photographs and 1920 × 1080 MP4 video at 60 frames per second. It brings high-resolution still photography and Full HD clinical video into the same examination platform.
