10MVAA - Motorized Variable Laser Attenuator

Motorized Variable Laser Attenuator
High initial transmission (T0 ≤ 0.85) at the range from UV to MIR"
Free of beam distortion and depolarization
Extremely low output beam deviation
For CW and pulsed (>10ps) lasers
For wide spectral range emission flux variation
High-precision and accuracy control of emission flux/power
Damage threshold >300MW/cm2
Fast response

Motorized Variable Achromatic Attenuator 10MVAA is designed to control emission flux of lasers and incoherent monochromatic sources -both in broadband spectral (200÷2400 nm) and large dynamic range (>60dB) of attenuation. Automatic control together with compact and robust design enables easy implementation of attenuation unit into complex optical and spectroscopic systems.

•    CW and pulsed laser (>10ps) precision emission flux/power control
•    Tunable lasers / optical convertors/ incoherent emission sources spectrum flatting
