Optical Fiber Attenuators
Collimator Variable Optical Attenuator
Description
The collimator variable optical attenuator is an useful attenuation tool, which the attenuation value can be adjustable by mechanical adjustment. It employs the principle of light shading between the two collimators to control the attenuation value. It features wide attenuation range, high precision, low insertion loss and compact size.
Applications
● Optic-fiber Communication Systems
● Optic Passive components test
● Optics Lab Use
