OPCO precision Filters are designed and manufactured to add value in the end use application.

Skilled opticians operating in a modern manufacturing facility produce custom Filters in prototype to production quantities.  Utilizing a vertically integrated approach to the manufacturing process, CNC fabrication, high performance coating, and precise metrology and testing assure repeatable accuracy, cost-effective Filters, and on-time delivery.

Typical Produced Include:

• Round Filters
• Square Filters
• Custom Shaped Filters
• Coated Filters
• ND (Neutral Density) Filters
  

Materials Used

• Per Customer Specification

To reduce lead times we maintain an inventory

of the most popular raw materials used.
