Description:
Beam splitter is widely used in the image science, laser measurement industry etc. It is an optical device that splits a beam of light in two. In its most common form-cube, CPG provides full solution of your needs, based on our precision quality control of the prisms and professional experiences in use of glue or optical contact methords. We helped our valued customers to overcome the market more than before.
With different materials and different coatings, CPG optics can provide a range of products, such as PBS, WBS, NWBS, NPBS, LWPBS, SWPBS etc. CPG optics provides the services: design new, optimize or NRE exiting products etc.
Still, we can use only one piece of coating windows to control the light. Usually we use an alluminium layer with the thickness of the aluminium coating such that part, typically half, of light incident at a 45 degree angle is transmitted, and the remainder reflected. Beyond a metallic coating, we also apply a dielectric optical coating, in this way, we can help our customers to set up their laser systems etc. We also provide pellicle mirror for our photography customers.
Other Dimensions of Non-Polarizing Beamsplitters that CPG Handles:
CPG optics also provides different sizes of the beam splitter, we can handle 0.2mm to 200mm.
Materials we already use: optical glass, birefringent materials, and even some plastics.
