Over 100 Additional Gratings are Available on Request

** Standard grating size is 68x68mm. 68x84mm gratings available as an option.

Note: preserve the light collecting power (aperture ratio) when operating at high wavelengths (high grating angles).  68x84mm gratings benefit operation above 1.2 µm with a 1200g/mm grating.

For non listed gratings see http://www.newport.com/store/genproduct.aspx?lone=Diffraction-Gratings&id=5248&lang=1033
