VBS-22 Evanescence-Based Variable Split Ratio Fiber Splitter/Coupler

Peak Wavelength Response 2.2, 2.5 µm; Active Area 0.25-10 mm²; Time Constant <100->300 µs; Resistance 0.2-10 MΩ; Typ. Bias Voltage 10-500 VDC New England Photoconductor’s range of lead sulfide (PbS) plate cells series for room temperature applications is available as “open” A, B, and C detectors, as well as hermetically sealed (AM, BM, CM). These detectors in TO-3, TO-5, TO-8, and TO-46 packages feature standard size active areas ranging from 0.25 mm² to 10 mm² – special sizes are available upon request. C Series components can be gridded for low resistance. The PbS room temperature detectors can be supplied with or without leads.   Code Number Active Area Typ.

Gas Leak Rate <1 x 10-8 scc/s; Fiber Type SM, MM, PM, High-Power Fibers; Cladding Diameter 125 to 1000 µm; Sealant Teflon, Viton; Operating Temperature -180 to +230 °C OZ Optics’ VAC series of fiber optic vacuum pressure feedthroughs provide a simple way to use optical fibers with vacuum and pressure chambers. They are available in two versions - a penetrating feedthrough fiber version and a receptacle style version. Penetrating versions have the fibers directly installed. One or four fiber versions are available. The fibers are installed in the OZ Optics factory. The fibers pass through a soft sealant material which is compressed by the compressive endcap and internal squeezer of the feedthrough. This conforms the sealant material surrounding the fiber, sealing the hole. A variety of sealant materials can be used. Viton is recommended for most applications up to +230 °C, and Teflon for cryogenic applications. A 1/4” NPT thread vacuum feedthrough is our standard. 1/8” NPT thread is also available for single channel assemblies with no connectors. In penetrating versions, the fiber can be protected in 900 µm loose tubing or a 3 mm OD stainless steel cable. The receptacle style version contains a short fiber stub, which is sealed using a vacuum rated glue. An O-ring is used between the chamber wall and the flange to seal the system. Adapters for various standard connectors are available. Key Features: Vacuum or Pressure Seal; Fiber in Penetrating Style Can Be Protected in Loose Tubing or Stainless Steel Cable Rugged Design Compact Low Transmission Loss (Excluding Connector Losses) Easy Installation Wide Range of Connector Types Single Fiber and Four Fiber Penetrating Versions Available Receptacle or Penetrating Type Available Operating Temperature Receptacle Type: -35 to +90 °C Operating Temperature Penetrating Type: -20 to 230 °C (Viton), -180 to +230 °C (Teflon) Applications: Laser Power Delivery or Optical Sensing in a Pressure or Vacuum Chamber
