Lens Modification Quote Request Form – Step 1 of 2

Please complete the form below to request a quotation for a customized lens. First, type the stock number of the off-the-shelf lens that is the closest match to your requested item so that it may be used as a reference lens. Next, select the required anti-reflection or reflection coating. After, fill in the finished part diameter and check the box if edge blackening is needed to decrease stray light. Lastly, please provide the requested quantity, information about the application, and any additional requests or notes.

Is the total transmission in your application not enough? Try an anti-reflection coating on your optics. See what EO has to offer.

Spherical optics, aspheric lenses, prisms, imaging lenses, imaging and laser optics assemblies, and mechanics are just a few of our expertise.

EO offers metallic coatings with high reflectance values for wavelengths ranging from 250nm to beyond 10μm. Find out which coating will be best in your optical system.
