Laser Line Non-Polarizing Plate Beamsplitters
Laser Line Non-Polarizing Plate Beamsplitters
Newport's laser-line non-polarizing beamsplitters are insensitive to the polarization of the incoming beam. Polarization components are matched to within 5%.
- Virtually zero absorption for true 50/50 beamsplitters
- Designed for 45° angle of incidence with random polarization
- AR coated back surface eliminates ghosting
- Slight wedge to eliminate internal fringes
- Convenient mounting in standard optical mirror mounts See All Features

Features
Laser Line Beamsplitter Construction
Our laser line non-polarizing beamsplitters exhibit exceptional performance in higher power applications, where cemented cube beamsplitters fail. Manufactured from high precision N-BK7 material to minimize wavefront distortion, this optic has a slight wedge to help eliminate back reflections to the laser. The front surface is coated with a multilayer all dielectric non-polarizing beamsplitter coating optimized for a specific laser line. The back surface is coated with a multilayer dielectric antireflection coating to minimize surface reflection losses and eliminate ghost images.
Better than Broadband Dielectric Beamsplitters
Unlike broadband dielectric beamsplitters, which are extremely polarization sensitive, Newport's laser-line non-polarizing beamsplitters are insensitive to the polarization of an incoming beam. The polarization components are matched to within 5%. Near zero absorption from these dielectric beamsplitters results in a true 50/50 split and high damage threshold, regardless of the incoming polarization.
N-BK7 Substrates
N-BK7 is an excellent lens material for most visible and near infrared laser line applications. It is the most common borosilicate crown optical glass, and it provides great performance at a good value. Its high homogeneity, low bubble and inclusion content, and straightforward manufacturability make it a good choice for transmissive optics.
