Description
Features
- Fixed 90° beam deviation, no image flipping & mirror reversal, outputs upright normal image
- Ultra-precise 90° roof angle; tolerance＜4 arcsec to avoid double ghost images
- Total internal reflection, high reflectivity, low stray light & clear imaging
- Compact integrated structure, shorter optical path than Porro prism systems
- Made of BK7 optical glass/fused silica, with high-transmittance AR multi-coating
- Low wavefront distortion, stable angle accuracy, long service life
