Optical Beamsplitters
1. Overview
Beamsplitter is also a kind of filter,it is used to split or combine laser beam. However Polarization BeamSplitters are used to split or combine two perpendicular polarization laser beam. The performance of beam splitter depends on the coating specifications. For the coating curves of each types of beamsplitters, please refer to Coating section for more information. To select a suitable beamsplitter, you need to consider the type, coating, transmission range and damage threshold.
2.Types
Alpha Optics is offering the following types of beamsplitters:
Plate Beamsplitters
Cube Beamsplitters
Panta Beamsplitters Cubes
3.Application
Laser Systems
Flrorescence Application
Imaging System
Life Science etc.
