dichroic mirror

Dichroic Mirrors

Dichroic Mirrors, also known as dichroic mirrors, are commonly used in laser technology.

Product introduction:

  • It refers to separating the light source into a specific spectrum and changing the direction of part of the spectral light path when incident at 45 degrees or at a large angle.
  • It is commonly used in sensors such as enzyme labeling instruments, fluorescence microscope systems, projection light engine systems, laser lights, optical instrument beam splitting, and video glasses. system.
  • It is an optical component that optical designers are passionately pursuing. It can effectively reduce the structure of the device to achieve multi-functional optical paths.

Features:

It is characterized by almost complete transmission of light of certain wavelengths and almost complete reflection of light of other wavelengths. The excimer dichroic mirror has the advantages of high transmittance, accurate wavelength positioning, and low optical energy loss.

Important Parameters

  • Reflectivity: Reflectivity refers to the ability of a lens to reflect light of a specific wavelength. In dichroic mirrors, reflectance is a key parameter that determines how well the lens reflects light at a specific wavelength.
  • Transmittance: Transmittance refers to the ability of a lens to transmit light of a specific wavelength. Similar to reflectivity, transmittance is also an important indicator of dichroic mirror performance.
  • Wavelength range: The wavelength range determines the spectral range in which the dichroic mirror can work. Within this range, the dichroic mirror is able to maintain its specific reflection and transmission characteristics.
  • Angle tolerance: Angle tolerance refers to the tolerance of the dichroic mirror to the angle of incident light. In practical applications, the angle of incident light may vary, so angle tolerance is an important indicator of the performance stability of a dichroic mirror.

Types

  • Dichroic mirrors can be classified based on their reflection and transmission properties. Mainly divided into two types: short wave pass mirror and long wave pass mirror:
  • Short-wavelength mirror: It has a high reflectivity for short-wavelength light and a high transmittance for long-wavelength light.
  • Long-wavelength mirror: It has a high reflectivity for long-wavelength light and a high transmittance for short-wavelength light.
  • In addition, according to different application scenarios, dichroic mirrors can also be divided into medical dichroic mirrors, ultraviolet dichroic mirrors and other types.
