Holographic gratings from Gratingworks have a groove density from 40 to 6000lines/mm and cover a wavelength range from 0.1umto10um.Their fringe profiles of gratings can be sinusoidal, deformed sinusoidal, or triangular. Their diffraction efficiency is from 30% to 85% at their optimized wavelength. If only TM polarization is desired, the diffraction efficiency can reach 95%.
Customers can select either original holographic gratings or their epoxy replicas. Original gratings have attractive properties for many applications, such as lower stray light, environmental insensitivity, and a short production cycle. However, if stray light and temperature sensitivity are not issues in your applications, you might consider the replica. It has less variation in diffraction efficiency.
