Large-Format MWIR Lens

StingRay Optics, Keene, NH, offers a 50-mm midwave infrared (MWIR) large-format lens assembly with an optional microscanning and step-stare sensor capability. The lens can be a standalone solution for large-format detectors or used in conjunction with enhanced-resolution features. The lens is used with cooled cameras with focal planes up to 28 mm diagonal. The speed of the lens is based on an F/2.3 cold shield arrangement, and the 50-mm focal length is derived from the required 1-meter sampling area at an operating distance of 2.5 km. The lens provides diffraction-limited performance over the entire field of view.

A method of promoting healing of injured or diseased neurons from Ames Research Center involves pharmacological activation of the STAT3 alpha protein. Injured or diseased neurons heal incompletely or not at all because they are susceptible to apoptosis (cell death), or because they fail to engage in axogenesis - that is, they fail to re-extend their axons to their original targets. Natural anti-apoptotic, pro-axogenic mechanisms are stimulated artificially in the new method. Click here for more info.
