dichroic mirrorThe core principle is the interference effect of light and the reflection characteristics of multilayer dielectric films. It is usually composed of multiple layers of thin films, and the thickness and refractive index of each layer of thin film are precisely designed. When light is incident on a dichroic mirror, light of different wavelengths will be separated due to differences in interference conditions:

Specific wavelength reflection: Light of certain wavelengths will be reflected by high reflectivity.

Transmission of other wavelengths: Light of other wavelengths will pass through with high transmittance.

For example, short wave mirrors preferentially reflect ultraviolet light and transmit visible light, while long wave mirrors reflect infrared light and transmit visible light.

　　dichroic mirrorApplication fields:

Laser technology: A dichroic mirror is used in lasers as a reflector or optical isolator to achieve precise control and isolation of the laser, ensuring its stability and directionality.

Optical communication: In optical communication systems, dichroic mirrors can be used for the segmentation and merging of optical signals, improving the performance and stability of communication systems.

Biomedical: A dichroic mirror is used in fluorescence microscopy for light source selection, helping scientists observe the microstructure of cells and tissues.

Spectral analysis: As a spectral element, a dichroic mirror is used in a spectrometer to separate the light source into different spectral components for spectral analysis.

Stage lighting: In the stage lighting system, a dichroic mirror is used to achieve color separation, mixing, and adjustment, enhancing the visual effect of stage lighting.

In the field of photography, dichroic mirrors are used as filters, polarizers, etc. to improve the shooting effect.

In the field of solar energy, dichroic mirrors are used in solar panels to improve photoelectric conversion efficiency.
