Frequently Asked Questions
Holographic gratings are a type of diffraction grating that is created by exposing a polished negative to the interference of two laser beams, forming fringes and creating a sinusoidal pattern on the exposure medium.
Holographic gratings are less likely to produce a blaze and have a lower efficiency compared to ruled gratings. However, when the scribed width to wavelength ratio is close to 1, the efficiency of holographic gratings is virtually the same as that of scribed gratings.
Holographic gratings are commonly used in spectrometers, spectrophotometers, and monochromators.
The aluminized holographic gratings have great reflectivity in the ultraviolet, visible, and infrared spectral ranges.
Customers can select holographic gratings based on their size, groove spacing, and blaze wavelength requirements.
