Detector Filed of View - To Limit Background and/or Improve Signal to Noise

The field of view (FOV) for standard detectors is usually determined by the package aperture. Unless very cold background temperatures are involved, restricting detector FOV will not substantially improve detectivity. However, should the need arise, custom apertures can be installed either inside or outside the detector packages. Please contact our application engineers for specific FOV information.
