We can provide rectangular transmission grating based on quartz material, and we can customize the grating according to the number of cycles required by customers.
Rectangular grating can realize beam splitting. The splitting grating we provide can achieve one-two and one-three.
The theoretical efficiency of one-and-two grating can reach 81%. And the angle between the two separated light beams can be adjusted. The theoretical efficiency of one-minute three-grating can reach 87%. And the energy between the separated beams can be defined, and the angle can be adjusted.
Measured characteristics and actual processing effect of one-split-two beam splitter (the incident light power is 9W, the positive and negative first-order power is 3.43 W and 3.48 W respectively without coating, and the non-uniformity between light spots is less than 1%. The diffraction efficiency is 77%, which is close to the theoretical limit of 80%. If the coating should be able to reach the theoretical limit)
