- Low Group Velocity Dispersion (GVD)
- 400 nm Stack on Top Maximizes 400 nm Reflectance
- Ø1" Rounds
- Material: N-BK7
Our Ultra-Fast Mirror with low Group Velocity Dispersion (GVD) was designed and manufactured for an OEM customer that required a mirror with high reflectance at 400 nm and 800 nm simultaneously. The mirror was used with a femtosecond pulsed laser in a metrologic device that measures the thickness of an opaque film.
- S-Polarization Reflectivity: >99%
- P-Polarization Reflectivity: >98%
