MSE PRO™ BK7 Broadband Non-Polarizing Cube Beamsplitters
MSE supplies offers BK7 Broadband Non-Polarizing Cube Beamsplitters. The mixed layer of the broadband non-polarizing prism has a certain absorption of light energy, but it is not sensitive on the polarization state. The same spectral characteristic can be maintained at wide wavelengths, and is suitable for tunable lasers. Mixed splitter film pair is insensitive about the change of incidence angle. Considering the metal properties in the hybrid coating, it is recommended to use it at in the laser environment not very powerful.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
