Hermetically seal any electrical conductor or optical fiber in a KF, NW, or QF-type flange. A KF (Klein Flange) flange is a type of flange that is used to create a vacuum-tight seal between two surfaces. Thorlabs manufactures Ultra-High-Vacuum Compatible Fiber Feedthroughs for both CF Ø2. 75" (DN40) and KF40 flanged systems. These feedthroughs allow for optical coupling into ultra-high-vacuum (UHV) systems using SMA905-terminated fiber patch cables and mating sleeves. Each fiber feedthrough. LBTEK fiber optic flanges currently include two types: SM1 and SM05, which can convert FC/PC, FC/APC, and SMA connectors to standard SM series threads. These flanges can be used for coupling single-mode and multimode fiber couplers with other free-space mechanical components, or combined with lens. JCOPTIX provides fiber optic flanges in four series: threaded (optical wall), SM05 threaded, SM1 threaded and C-Mount threaded. It can achieve the conversion between FC/PC, FC/APC, SMA fiber optic connectors and standard SM series threaded connectors or C-Mount threaded, as well as the conversion. Optical fibre connection - fast and easy + Simple, quick and cost-effective solution – no core drilling required: a simple 10 mm diameter hole is sufficient! + Universally applicable: masonry with area sealing or wall made of waterproof concrete + 10 cm surrounding, oil and bitumen-resistant foil. Hermetically seal any electrical conductor or optical fiber in a KF, NW, or QF-type flange.
