High Power; Insertion Loss <0.5 dB; Power Handling ≤50 W; Shutter Response Speed <5 ms; Shutter Electrical Interface 5 V TTL In response to increasing demand for high power handling fiber optic components, OZ Optics has developed the HPCR / AA-250 / SH-200 series of fiber optic shutters and connectors that incorporate smart sensors for safety interlocks. These shutter systems can be incorporated in high power handling components, including freespace-to-fiber and fiber-to-fiber coupling situations. For extreme power handing capabilities, the shutters can also incorporate additional beam dumps and/or heat sinks to safely absorb the blocked laser power. The key components that allow realization of smart shutters and safety interlocks are a series of proximity sensors and temperature sensors installed at suitable locations in the body of fiber optic assemblies. These provide the necessary electrical signals to alert the end user to take appropriate action. Key Features: Multiple Watt CW Power Handling Shutter Speeds of <5 ms Controlled via 5 V TTL Signal Available with Temperature and Connector Proximity Sensors for Safety Interlocks Compatible with SMA 905 and FC Connectors Available in Laser-to-fiber and Fiber-to-fiber Versions Fiber Connectors and Receptacles with Safety Sensor/interlocks Available Applications: All Situations Involving Laser Beams, Including High Power Laser Beams Coupled into SM or MM Fibers; Laser Facilities Requiring Compliance to Laser Safety Standards; High Power Industrial and Medical Laser Applications - Laser Marking, Cutting, Welding, Laser Scalpel, Eye Surgery, Tattoo Removal; High Power Laser Physics; High Power Spectroscopy; OEM Laser Systems

Focal Length 0.91-5.95 mm; Numerical Aperture 0.56-0.86; Design Wavelength 4-9,5 µm; Outer Lens Diameter 3.000-8.000 mm; Working Distance 0.66-5.00 mm GH Optics’ series of infrared lenses are aspheric optics, precision molded in IR glass, designed for use in the short-wave, mid-wave, and long-wave infrared (SWIR, MWIR, LWIR) bands. Typical applications are collimating or focusing (laser) beams, but also coupling quantum cascade lasers (QCL). With their large numerical apertures, these precision molded infrared aspheric lenses provide optimum collection of light for infrared lasers (short wave (SWIR), mid wave (MWIR) and long wave (LWIR) types), as well as quantum cascade lasers (QCL). Two types of chalcogenide glass are available: GH6, made from As40Se60 material, is most popular and widely used. This material is comparable to infrared glass of other leading brands in the market, features high transmission, is Ge free and RoHS compliant and can be molded, grinded and polished. GH2, made from Ge28Sb12Se60 material, is especially suitable for collimating lenses, gas testing and coupling of quantum cascade lasers (QCL). This material also is comparable to infrared glass of other leading brands in the market, featuring high transmission and RoHS compliance. Lenses made from this material can be molded, grinded and polished and are suitable for high-temperature applications.
