Third Generation Sensors | Optical Dewar Link for Focal Plane Detectors
Infrared focal plane detector Dewar components integrate optical elements. Optical Dewar packaging: Built-in optical components (filters, field lenses, aperture stops, cold shields, etc.) are included. 1. Optical lenses replace planar optical windows (simplifying system design, applicable to focal planes). 2. Cold shield integrated optical lenses (spatial non-uniformity correction?). 3. Variable cold aperture (dual F-numbers F/3, … Read more
