• Windows protect costly lenses from many damage. (e.g. dust, damege from spattering)
  • These apllication are moniter to into the vaccum furnace, heating furnace etc.
  • Usually, We have windows stock. Please inquiry about details.

  • The spherical lenses are used for the Camera, lasers, and various measuring machine.
  • The spherical lenses are low coat lenses compared to aspherical lenses.
  • Optical materials have characteristic data with each other. So optical materials and curvature are decided from using wavelength, and average laser power, etc.
  • We can supply convex lenses, concave lenses, biconvex lenses, biconcave lenses, and meniscus lens etc.
