Electronic Variable Fiber Optic Attenuator - EVOA800F
Electronic Variable Fiber Optic Attenuator
Product Specifications
The Electronic Variable Optical Attenuator with Power Lock, FC/PC, 780 to 980 nm by Thorlabs operates in the spectral range of 780 to 980 nm. With a maximum input power of 200 mW and attenuation capability ranging from 1.5 dB to over 25 dB, it features calibration set points at 785 nm and 852 nm, as well as a user-defined option. Ideal for precision light control in optical systems, it ensures high return loss (≥40 dB) for reduced signal back reflection.
