Customized Injection Angle 45 Degree Dichroic Mirror Dichroic Lens for Enzyme-Labeled Instruments and Fluorescence Microscopes

Dichroic mirrors/Lenses can separate light beams according to wavelength. The two sides are respectively coated with a filter film and an anti-reflection film, the dichroic mirror exhibits high transparency or high reflection for different wavelength beams, so it is often used to split/combine beams of different wavelengths, or filter out a certain wavelength band. 

According to the different effects on the band, dichroic mirrors can be divided into three types: short-wave pass, long-wave pass and multi-band. 

1. Shortwave pass is highly transparent to light below the cut-off wavelength, and light above the cut-off wavelength is highly reflective; 

2. Long wave pass is highly transparent to light higher than the initial wavelength, and highly reflective to light lower than the initial wavelength; 

3. The multi-band dichroic mirror has three or more transmission or reflection bands, the band between the cut-off wavelength and the starting wavelength is high in transparency, and the other bands are high in reflection.
