Motorised Attenuator, Compact, Spectral range 350-1550nm

Manufacturer's part number :

2-PWRXP

Manufacturer Altechna

Altechna

Description :

Compact version of Altechna’s Motorized Attenuator. This device attenuates free space laser beam (or pulse) continuously without introducing additional energy fluctuations. Contrast better than 3000:1 (Tp:Ts) is achieved since this attenuator is mounted with high contrast polarizer. This very compact version of attenuator can be easily integrated in custom optical systems.
