The grating curves show typical relative efficiency for the various blaze wavelengths for selected gratings and should be used as a comparison guide only.

Note:

Use 68 x 84mm Grating
When operating at high wavelengths (high grating angles). the 68 x 84 mm grating preserves the light collecting power (aperture Ratio)

Central Wavelength to High
Refers to the mechanical rotation capability (not the operating or optimum range) of a grating drive. Lower the central wavelength or select a grating that allows operation over your required wavelength region.

CCD Resolution (FWHM)
Refers to the resolution available with the selected detector or image intensifier. Calculated as a typical FWHM = 2.5 pixels used as reference, actual values may vary.

Spectral Coverage:
approximate, use for reference purpose only.
