VFT Fiber Vacuum Pressure Feedthroughs

Product information "VFT Fiber Vacuum Pressure Feedthroughs"

Single Channel; Fiber Type Step Index Multi Mode; Core Size 200 to 600 µm; Flange Options Bolt, Conflat & ISO Klein Flange; Connector Type SMA905

Fiberguide’s VFT series of fiber vacuum pressure feedthroughs is designed to allow optical fibers to penetrate a pressure vessel without compromising the integrity of the vacuum. The VFT series can be configured as stand-alone feedthroughs or integrated into cable assemblies as needed.

The VFT series of vacuum feedthroughs are ideal for laser power delivery or optical sensing applications that must be conducted in a pressure or vacuum chamber.

Optional specifications for the VFT series of vacuum feedthroughs are pigtail or bundle configurations, alternate connectors or fiber types as well as variants for high or low temperature.

WaveShaper® 1000A Programmable Optical Filters
1468.0-1640.0 nm; Filter Bandwidth 0.01-9 THz; Connector Type FC/UPC, FC/APC; Wave Manager S/W for external PC With a highly advanced high-resolution, solid-state Liquid Crystal on Silicon (LCoS) optical engine, II-VI Incorporated’s WaveShaper® 1000A series of programmable optical filters provides a range of programmable optical filtering and switching options for optical R&D and production test applications. WaveShaper® 1000A systems allow extremely fine control of filter characteristics, including center wavelength, bandwidth, shape, dispersion and attenuation, and support arbitrary user-generated channel and filter shapes. Various models are available which cover the entire range from the S- to the extended L-band. The bandwidth can be set from 10 GHz up to more than 5 THz with 1 GHz increments for the standard C- or L-band version of the 1000A. The X version – which covers C+L band – and the S-band and the extended L-band versions support filter bandwidths from 20 GHz to about 9 THz. The required filter shape (both amplitude and phase) can be generated by the user and then loaded into the WaveManager software, which translates the user specification into the required optical shape. Band-stop and optical comb filters are also supported as is optical power control over a range of more than 35 dB for all filter types. All these filters are equipped with standard single mode (SM) fibers. In addition, a family of WaveShaper® 1000A programmable single polarization filters is available on request – this series comes with polarization maintaining (PM) fibers. Please contact AMS Technologies for more details.
