Transmission Grating
Product description
Transmission grating
Transmission Grating
- Both high dispersion and high diffraction efficiency.
- Diffraction efficiency full spectrum low polarization dependence
- Excellent environmental stability, tolerance to 500 °C working environment.
- Compared with volume holographic phase grating, the angular tolerance is larger.
- Low stray light and low wavefront error
- No organic materials, high laser damage threshold.
