Wg1031 Handheld Single-Mode Optical Attenuator

summary
WG1031 handheld optical attenuator based on MEMS VOA device, with built-in precision digital control and output optical power monitoring
Control circuit. The attenuation can be adjusted in increments of 0.1dB, and the output optical power value can be displayed in real-time on the LCD screen. six
A commonly used working wavelength that has been rigorously calibrated to meet different measurement requirements. This instrument has a USB communication interface,
All testing processes can be controlled by external programs to facilitate the construction of automated measurement and control systems
characteristic
Built in output optical power monitoring.
The light decay reaction is rapid and the output is stable.
