Determine the displacement of a collimated beam incident on a tilted plane-parallel plate, or window. This displacement is dependent on the angle of incidence, the thickness of the plate, and the refractive index of the plate. This calculator also determines the displacement of the secondary reflection resulting from a small portion of the beam reflecting off the glass-air interface of the plate.The exit beam will be parallel to the input beam and magnification remains constant when imaging through a plane-parallel plate.

Don’t fear! These lenses are coated with Anti-Reflective thin-film coatings using the most advanced technology – Ion Beam Sputtering (IBS). The near bulk density of thin-film AR coating allows lowering the absorption to the minimum and thus reaching very high transmittance values. Feel free to take a look at our lens options of various focal lengths and radiuses of curvature.Disclaimer - where Focal Lengths or ROC's are not specified in the product description, the values are calculated at the design wavelength of the coating. They are for reference only.
