Transmission gratings can be used in teaching spectrometer or as beam splitters. We can replicate transmission gratings from almost any of our plane reflection gratings. The groove densities of transmission gratings including100l/mm,200l/mm,300l/mm,500l/mm and 1000l/mm are often used.
If the transmission gratings are used in precision measure instruments as beam splitters, we need redesign and produce a new.
