61-6914-21 Biconcave Lens (Synthetic Fused Silica) φ50mm Focal Length -79.5mm SLSQ-50B-80N

Features

  • By making both sides concave, this lens can efficiently refract light in a small space and spread light widely.
  • This function can be used to increase the area of illumination.
  • A lens made of synthetic quartz that can be used with ultraviolet light below 350 nm.
  • It can be selected according to your specifications from the wide variety of subdivided by outer diameter size and focal length.
  • * The concave lens cannot collect light or tie a real image by itself.
  • * Use in combination with convex lenses.
  • * Spherical biconcave lenses have chromatic aberration, and the focal length depends on the wavelength.
  • * When a high-energy pulsed laser is used, the condensing point is connected to the optical path by the reflected light of the concave surface, and a spark may be generated.
  • * When using with a pulsed laser, use a flat concave lens.
