- W is the blank dimension in mm parallell with the grating grooves
- H is the blank dimension in mm perpendicular to the grating grooves
Standard values:
- Groove densities: Spectrogon manufactures 600 grooves/mm to 3600 grooves/mm on a regular basis. For lower or higher groove densities please contact our sales team.
- Wavelength range from UV to approximately 2000 nm
- Standard sizes: 25 x 25 x 6 mm, 30 x 30 x 6 mm, 50 x 50 x 6 mm, , 50 x 50 x 10 mm, 58 x 58 x 10 mm, 64 x 64 x 10 mm, 90 x 90 x 16 mm, 110 x 110 x 16 mm, 100 x 140 x 20 mm, 120 x 140 x 20 mm
