Lenses for Front End Imaging and Spacers

There are times where beams are simply too large to profile with conventional methods of directing the beam, or a sample of the beam, into an imager for analysis. In this case, an imaging lens can be fixed to the front end of the imager and focused down to a plane where the beam is being projected.

    When direct imaging in front of the camera, like imaging an image projected onto a defusing surface, like a ground glass plate, it is necessary to reduce the image so that it completely fits onto the CCD chip surface. The 25mm and 50mm CCTV lenses image an object from a given plane in front of the lens onto the CCD while reducing the size.
