Use this Photonix PX-E102 Meter ST Adapter Cap with Techlite Series Power Meters. Attach an industry-standard fiber connector to a standard 7/8"-28 optical input port. Constructed of machined aluminum alloy, this anodized adapter offers long life and excellent dimensional stability. Cap features one-piece or top-insert construction, preventing top impacts from driving connector adapter into detector head's delicate and expensive crystal. The caps' weighted and balanced split knurl design allows easy spinning with the flick of a finger.
Crush-resistant adapter has an open-bore design, and no surface comes in contact with the fiber or ferrule endface. This virtually guarantees that the quality of the optical surface will not be degraded when connected to the meter. Two-year warranty.
