Concave Diffraction Grating
Gratings
A concave grating for spectroscopy and spectral imaging, quoted from groove density, blaze wavelength, efficiency and substrate.
Typical values
| Parameter | Reference |
|---|---|
| Reference groove density | 300–1200 g/mm examples |
| Reference blaze wavelength | 250–1000 nm examples |
| Reference dimensions | 25–50 mm examples |
| Reference substrate | Fused silica |
| Reference coating | Al or Au |
| Efficiency target | By design review |
This is a drawing-led item. The reference values below help frame the discussion; the pattern, groove or spectral data on your drawing controls the quotation.
Concave gratings combine dispersion and focusing, which makes the radius, groove density and blaze wavelength part of the optical design. Provide the wavelength range, resolution target, entrance slit and detector geometry so the grating can be reviewed with the system.
