BIOLIT 2
Femtosecond Fiber Laser for Biophotonics
The Biolit 2 is a compact, air-cooled femtosecond laser designed for multiphoton microscopy, biophotonics and other non-linear optics applications. The industrial-grade device is exceptionally robust, maintenance-free and affordable. A combination of ultra short (typ 55 fs) and clean pulses with integrated dispersion compensation, excellent beam quality and optimized repetition rate enables unparalleled quality multiphoton imaging while preserving the object.
