The SWIR hyperspectral lenses have an improved design and a lower F/#, to produce superior images in dark settings. The new sturdy design of the lenses provides remarkable performance, better transmission, and image quality from the visible spectrum to the SWIR region. The OptiStar lenses operate in the wavelength range of 500 – 1700 nm with a transmission of 90% +/- 5% across the range. Both the OptiStar and standard SWIR lenses come with auto iris or manual functions.
Navitar’s VP of Product Development, Craig Fitzgerald stated that the lenses were designed as per the requirements of customers. He added that the OptiStar lenses were developed by collaboration between the manufacturers of SWIR and Navitar cameras. The partnership allowed Navitar to manufacture a multifaceted lens series that can be integrated with various cameras, Fitzgerald said.
