BK7A Broadband Plate Beamsplitters
BK7A Broadband Plate Beamsplitters
Product name : BK7A Broadband Plate Beamsplitters
Description :
● Spectrally flat performance over a broad wavelength range
● Equal (50 : 50) split ratio T and R
These dielectric coated plate beamsplitters are intended for use with broadband or multi-spectral sources. They have a flat performance with a controlled equal split ratio. The s and p components are separated by up to 30% and in combination they provide an average transmittance and reflectance close to 50%. Absorption and reflection losses are minimal.
