Basic Info

Model No.:  VYO-0025

Product Description

Model NO.: VYO-0025 Type: Concave Lens Shape: Single-lens Lenses Color: Clear Customized: Customized Dia. 188.20mm: 7.41 Transport Package: as Requested Origin: China Usage: Optical Transmittance: >95% Material: Optical Glass Certification: RoHS, SGS, ISO9001 Coating: Customized Trademark: VY or OEM Specification: RoHS, SGS HS Code: 9001909090 Plano-Concave Spherical Lens has a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses.This lens is widely use in optical display systems, projection optics systems, imaging and laser measureemnt systerms;
