| Substrate Material | BK7 Quartz Glass |
| Type | Flat-Flat |
| Size Error | ±0.25mm |
| Clear Aperture | ≥90% |
| Surface Quality of the Polished Surface | scr/dig: 40/20 |
| Surface Quality of the Grinding Surface Ra | 2.5 |
| Surface Accuracy，λ@633nm | 1/2 |
| Coating | Protect the Gold Film |
| Thickness of the Gold Coating Layer | ~400nm |
Technical Parameters
The typical reflectivity curve is shown as follows. The data only presents the reflectivity performance below 1000um. In actual operation, the wavelength can be higher.
