Semi reflective and semi transparent spectrophotometer

Optical splitter, also known as optical beam splitter, can split light beams according to different wavelengths and intensity ratios.
This effect is achieved through different optical designs, such as a semi transparent and semi reflective splitter, where half of the light can be reflected and the other half can be transmitted. The splitter only splits the light from an energy perspective and optimizes the splitting ratio according to different wavelength ranges. For example, 50% reflection: 50% energy splitting, 30% reflection: 70% energy splitting.
Common spectral ratios: 10T: 90R, 20T: 80R, 30T: 70R, 40T: 60R, 50T: 50R, etc
A beam splitter is a type of optical glass substrate with a semi reflective semi transparent film coated on its surface and an anti reflective film coated on the other side, which can split a beam of light into two beams.
A beam splitter reflects a portion of the incident light energy, absorbs a relatively small portion, and transmits the remaining energy. Made by vacuum evaporation, the light passing through the filter can change the transmittance ratio, for example, it can penetrate half and reflect half, with low absorption characteristics.
