概述
- Full dielectric membrane layer
- High damage threshold
- Optical component material: K9, UV fused silica
- Size: Ø12.7mm, Ø25.4mm, Ø50.8mm
- Band range: 355nm, 515-532nm, 532nm, 633nm, 780-795nm, 1053-1070nm
- The spectral ratio is 50:50 when the angle of incidence (AOI) is 45°
Dimension-Labs' Non-Polarizing Beamsplitter Plates are available in three different substrate sizes: Ø12.7mm, Ø25.4mm, and Ø50.8mm, and can provide a 50:50 spectroscopic ratio over the bands 355nm, 515-532nm, 532nm, 633nm, 780-795nm, and 1053-1070nm. The coating on the beamsplitter mirror is optimized for a 45° angle of incidence (AOI) and has long-term stability.
To reduce unwanted interference effects (such as ghosting) caused by the interaction of reflected light on the front and back surfaces of the optical components, the back surface of all beamsplitters is coated with a reflection enhancement film.
