Aspheric Lenses (High Precision CNC Machined)

We produce aspheric lenses from standard optical glasses up to 400 mm in size and welcome custom lens requests.

If you need help selecting or designing the lens for your application, our optical designer team will gladly help you.

Please consult the corresponding PDF and Optics Studio (Zemax) files available under the LENS TABLE tab for more information on our catalog lenses.
