Tander-Link is a U.S.-based supplier of custom and wholesale optical materials, supporting industrial, scientific, and advanced sensing applications.

We work closely with a network of vetted manufacturing partners to deliver precision optical components built to specification. Our role is to simplify the process for clients who need reliable execution, clear communication, and repeatable quality — without unnecessary complexity.

Most of our clients engage us as a long-term supplier, returning for reorders and new programs where consistency and follow-through matter.
