optical holographic blazed gratings

China star optics can provide customers with a variety of replicated grating products such as Plane Ruled diffraction grating, transmission gratings and holographic grating to meet different needs.Plane Ruled Reflective Gratings are available with blaze wavelengths 500 nm or 1000 nm and optimized for use at 350-800 nm or 700-1600 nm respectively. These Plane Ruled Reflective Gratings are characterized by a superior efficiency at their design wavelength compared with holographic grating.  Plane ruled Reflective Diffraction Gratings are an excellent choice for spectroscopy setups using silicon detectors or fiber-optic telecommunication applications for which higher reflectivity in NIR/IR spectral regions is required.  Custom sizes of holographic concave grating and holographic blazed grating are available on request. Mark diffraction grating for orientation and optical direction. Note: The surface of the plane ruled grating and holographic grating are ve…
