Gratings for near IR (700 to 1100 nm)
Best-in-class high efficiency transmission gratings for pulse compression, high power beam combining, remote sensing and spectroscopy applications.
The gratings are fabricated using DUV Projection Photolithography and Reactive Ion Etch in hard dielectrics and high purity Fused Silica substrates.
We also offer custom transmission gratings fabricated to your specifications, including custom wavelength range, line count, size and performance levels.
