Beam sampling grating (Beam sample grating) by extracting energy (0.2%), little laser measurement of laser power and energy. The device in the melting quartz substrate surface making the varied-line-spacing grating, both sampling and is focused on the function, with light energy loss is small, the characteristics of high laser damage threshold is currently one of the best way of high energy laser energy measurement.
Sampling grating is continuous variable spacing grating, grating linear density per mm from hundreds to thousands of lines. The required specifications can be customized according to user needs.
Product specifications:
The optical diameter 10 mm - 500 mm. Such as 430 mmx430mm, 360 mmX370mm, 430 mmX340mm, 200 mmX200mm, etc.
Sampling rate is 0.2%, 0.3%, 0.5%
