Description
Overview
GAOTek optical variable attenuator machines can conveniently and rapidly complete the continuous variable attenuation of 0 dB to 30 dB or 0 dB to 60dB of optical signal, with high attenuation accuracy of 0.1 dB, providing the light attenuation function of five commonly used wavelengths, backlight adjustment function, accurate attenuation accuracy, and user self-calibration function.
