Spectral splitter and half mirror
A beam splitter is a special optical processing substrate coated with high-precision optical media to ensure no ghosting, high smoothness, no black spots or stray light in imaging. It is used in optoelectronic sensing devices such as optical instruments, biochemical and medical instruments. A beam splitter is actually a beam splitter with sharp edges. It is coated with a special film on the surface, which allows the incident light to reflect half and transmit half, thus dividing a beam of light into a reflected beam and a transmitted beam, forming two beams. The beam splitter reflects a portion of the incident light energy, absorbs a relatively small portion, and transmits the remaining energy.
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. This effect is achieved through different optical designs, such as semi transparent and semi reflective mirrors, where half of the light can be reflected while the other half passes through the lens. Prisms and other optical structures can also be used here, such as pure reflective splitters that can split incident light in different directions. Because many metallic substances have high reflectivity in the infrared spectrum range, such reflective devices are very suitable for infrared spectroscopy. In addition, with a simple structural design, each individual beam of light can have the same reflection intensity.
Advantages of spectrophotometer:
1、 Accurate light separation ratio with good spectral characteristics within the wavelength range.
2、 Very good uniformity
3、 Metal spectrophotometry has a wide spectral range, is insensitive to angle changes, dielectric thin films have no absorption, and accurate spectral ratios.
4、 Through plasma electroplating and ion sputtering assisted dielectric film, the film layer is dense and dense.
5、 Good temperature and humidity stability.
A beam splitter is an optical component coated with a semi transparent mirror film on its surface, which can split a beam of light into two or more beams. A beam splitter reflects a portion of the incident light energy, absorbs a smaller portion of the light, and transmits the remaining energy. The spectrometer has obvious neutral color characteristics. This spectrometer is made by vacuum evaporation of multi-layer dielectric films. No problem, the metal film will be absorbed. The sum of penetration and reflection ratio is close to 100. Function: Vacuum evaporation. After passing through the filter, the transmittance of light can be changed. For example, it can be semi transparent and semi reflective, with low absorption rate.
