  • MWIR Lens Assembly

KEENE, N.H., April 11, 2008 -- A 50-mm midwave infrared (MWIR) large-format lens assembly from StingRay Optics has an optional microscanning and step-stare sensor capability for enhanced imaging requirements and can be used as either a stand-alone solution for large-format detectors or in conjunction with the enhanced-resolution features.

The MWIR large-format lens assembly offers diffraction-limited performance over the entire field of view (FOV), enabling the microscan image enhancement feature to achieve the highest potential clarity, the company said. The microscan and step-stare subassemblies can be added as an upgrade to the base 50-mm lens.

The micro-scanning system for which the lens was originally developed is being used to determine the inherent benefits of image dithering and processing, with an emphasis on decreasing ground sampling distances, StingRay said, and it step-and-staring FOV feature is intended to explore both optical and mechanical methods to rapidly survey and stitch the field of view to produce a system with a substantially larger field of regard.
