Optical filters and filter holders
FC-fiber adapters
Jacks for easy alignment
The model 1280 filter holder allows you to mount 1-diameter filters using either an included Delrin® ring or a setscrew (depending upon filter thickness). Since they screw directly onto the photodetector housing, no unwanted light can reach the photodetector itself. This accessory is especially useful when using narrowband filters with our femtowatt photoreceivers.
The model 1281 FC-fiber adapter conveniently attaches optical fibers with FC connectors to our photodetectors so you can use the same photodetector for both free-space and fiber experiments.
