Collimating Lens
Lamps
Sunday-optics
Enclosure material: Aluminum or Copper Optical element: Aspheric lenses, two-element lenses, three-element lenses (glass), single rubber rings, and two-piece rubber rings Dimensions: M6X0.5、M7X0.5、M9X0.5、M8X0.5、M12.7X0.5
A collimating lens converts light from each point in an aperture column into a parallel, collimated beam. Lens selection depends on aberration requirements. Simple plano-convex or biconvex lenses with larger relative apertures suit low demands; achromats with smaller relative apertures suit higher demands. Collimators are a key Sunday product, available as standard or custom designs. Sandi Optoelectronics offers single aspheres, doublets and triplets.
