Product Description
We manufacture kinds optical spherical lens professionally. Plano-Convex Lens is widely use in optical display systems, projection optics systems, imagining optical systems, and laser measurement systems. It is best use where conjugate point-- object distance, S or image distance S' is more than five times of the other. This lens is almost the most super form for both collimating a point source and focusing collimated light;
Plano-Concave 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;
Double-Convex Lens, also named Bi-Convex Lens, is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. It is used in beam expanders, . Projection optics systems, optical viewers etc;
We supply optical spherical lenses, include plano-convex spherical lens, plano-concave spherical lens, bi-convex spherical lens, bi-concave spherical lens, meniscus spherical lens, special spherical lens etc.
