Specifications
| Material | BK7, UV FS |
| Surface quality | 40-20 scratch & dig (MIL-PRF-13830B) |
| Clear aperture | 80% of the face size |
| Flatness | λ / 4 @ 633 nm |

Description
- Two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face
- Reflectance/Transmittance is 50 / 50 % with tolerance of +/-5% at designed wavelengths
All dielectric coatings of fixed ratio laser beamsplitters are optimized to be insensitive to split only s- or only p-polarization or only unpolarized light (R = (RS+RP)/2 and T = (TS+TP)/2) at designed wavelengths.
