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.
Applications
• CW and pulsed laser (>10ps) precision emission flux/power control
• Tunable lasers / optical convertors/ incoherent emission sources spectrum flatting
• Dynamical band-passing of super continuum
• PLE spectroscopy
• Photo-ESR spectroscopy
• PV devises inspection and testing, PV materials investigation
• Laser media and non-linear optical materials testing
• Photo-DLTS
• Material processing
