Singlet Lenses These lenses are polished to tight tolerances using master test plates to ensure minimum wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects. We have set up a special product line to produce small quantities of custom design optical components. Plano-Convex Lens is best used where one conjugate point (object distance, S or image distance S') is more than five times the other. This lens shape is near best-form for either focusing collimated light or for collimating a point source. 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. 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. Bi-Concave Negative Lens is like the Plano-Concave lens in that it is used to produce divergent light. The Bi-Concave is best used when the beam is converging.
