Details

Elliptical plate beamsplitters can be conveniently and accurately installed in various circular tubes, saving space and generating circular light spots.
Spectral flat plates are usually used at a 45 ° tilt, with one side coated with a spectral film and the other side coated with an anti reflective film. It 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. 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.
Guangtan Intelligent provides various types of elliptical spectrometers with pre coated spectral films and rear surface coated with VIS, NIR, SWIR anti reflective films.
Precautions for use:Please wear finger cots when using, and do not touch the surface of the spectrophotometer directly with your fingers to avoid residual fingerprints affecting the light transmission effect of the spectrophotometer.
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.
