If you are looking for plano-convex lenses, bi-convex lenses, or windows, Esco may already offer a catalog optic that meets your needs. By hovering over and/or clicking on the plotted specifications (represented as bullets) in the Catalog Part Graphs, you will reveal details on Esco’s available catalog optics.
For components not listed in the Esco Catalog Part Graphs, the user can submit a custom quotation form and our sales team will address your specific requirements immediately.
Where refractive index is required, common types are accessible using pull down menus. If there is a specific glass type or refractive index needed, you can find it on our master glass reference page.
Calculator Units and Sign Convention
Dimensional units are not needed unless they are required. With the exception of alpha and beta angles, which are in arc minutes, angular units are in degrees. Please note convex and concave sign conventions. The calculation accuracies are better than 16 significant digits, although less are shown in the display windows for screen space purposes.
Esco Equation Calculator
It is possible to enter an equation for an input. Simply start the entry with an equal (=) sign in any field. For those that are familiar with excel, it is much like entering a formula into a spreadsheet.
