 Transmission Gratings

Transmission Gratings are designed to disperse incident light at specific angles. Angular dispersion is a function of angle of incidence and groove spacing. Dispersion increases as angle of incidence increases or as groove spacing decreases. Coarse groove spacing maintains high efficiency while fine groove spacing reduces transmission at long wavelengths resulting in low efficiency.

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 including 100L/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 producted a new.

Note:

The sizes listed in this table are the maximum ruled areas. All gratings can be replicated to a smaller size and directly ordered. If you need a grating area more than ruled areas in the table or other specification, you must contact us in advance.
