  • Porro Prism
    Brand:
    Product Code:
    Model:
    Brief:
    It is a type of reflection prism which can be used to alter the orientation of an image
  • Sapphire Domes
    Brand:
    Product Code:
    Model:
    Brief:
    Optical domes are hemispheric windows which provide a protective boundary while allowing a clear field of view between two environments.
  • Rectangle Step Window
    Brand:
    Product Code:
    Model:
    Brief:
    Sapphire material has high hardness (Moths 9), high melting point (2050℃) and good thermal stability, with wear resistance, corrosion resistance characteristics. And in the infrared spectrum, it has a high transmission rate, can be used in the wavelength range of 200 nm - 450 nm.
  • Wedge Window
    Brand:
    Product Code:
    Model:
    Brief:
    Wedge windows are often used to deflect the incident beam to the direction at a certain deflection angle. When used in pairs, the outgoing beam can be positioned in any direction within a pyramid with the incident beam as the axis through the relative rotation of the two optical wedges.
  • Fused Silica Step Window
    Brand:
    Product Code:
    Model:
    Brief:
    The material of fused quartz has high temperature resistance, small coefficient of thermal expansion, good chemical stability and good performance in ultraviolet and infrared band. According to its optical properties, it can be divided into three categories.
  • CaF2 Window
    Brand:
    Product Code:
    Model:
    Brief:
    Calcium fluoride window/CaF2 window material has a light transmission range of ultraviolet light 0.13 ~ far infrared 10μm (there are five levels: IR infrared, VIS visible, UV ultraviolet, VUV vacuum ultraviolet, excimer level).
