光栅分辨率/色散计算器，用于确定每台Princeton Instruments相机和光谱仪组合的光栅分辨率。
For Richardson Gratings not listed go to https://www.newport.com/c/diffraction-gratings
Spectral Coverage: approximate, use for reference purpose only.
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)
Center 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.
