Details

Broadband Plate Beamsplitters are typically used at a 45 ° tilt, with one side coated with a spectral film and the other side coated with an anti reflective film. They can separate incident light into two parts: reflected light and transmitted light.
The front surface of the spectrophotometer is coated with a spectral film, and the back surface is usually coated with an anti reflective film to reduce the interference effects between light beams and ghost images. Spectral flat sheets are lightweight, reasonably priced, and relatively easy to produce. A beam splitter is an optical component that can split a radiation beam into several parts. According to different wavelengths and polarization directions, light can be split according to different light intensity ratios, and applied in optoelectronic sensing devices such as optical instruments, biochemical and medical instruments.
The optical probe intelligence can provide K9 broadband spectroscopic flat, elliptical broadband spectroscopic flat, aluminized lattice spectroscopic flat, and ultraviolet fused silica aluminized lattice spectroscopic flat. We not only provide a large number of standard spectrometers in stock, but also customize spectrometers according to your needs.
Note: This series is only applicable to non polarized light splitting. When splitting light beams with certain polarization states (partially polarized light, linearly polarized light, circularly polarized light, elliptically polarized light), please use a polarizing prism for intensity splitting.
