Acton’s standard narrowband optical filters are made from the highest-quality optical materials and are used in many research and industrial applications.

Filters are visually and optically inspected before they are shipped, and include individual transmittance curves to show each filter’s performance characteristics. Detailed “rejection” curves can be purchased at the time of manufacture. Other wavelengths and sizes are available, as are image-quality filters..

 Feel free to contact us with details of your custom or OEM filter requirements at info@actonoptics.com.
