New Near-Infrared Achromatic Lens for 8K Line Scan Cameras S5LPJ4465
Continuing advances in camera technology also require modern lens designs. Various camera manufacturers have introduced new line-scan cameras sensitive to four color channels. Conventional camera sensors detect only visible light, whereas these new cameras include a near-infrared color channel in addition to red, blue, and green. Conventional near-centric and telecentric lenses often cannot compensate for axial chromatic shift, leaving at least one channel at a spectral edge blurred, particularly the blue and near-infrared channels. The RGB-NIR lens S5LPJ4465 has a focal length of 65 mm and is optimized for 8k resolution, with a pixel size of 5um and a line length of 40 mm. It provides four-color-channel (RGB-NIR) imaging with high-precision achromatization, eliminating axial chromatic shift, and is particularly suitable for Teledyne Dalsa line-scan cameras. RGB-NIR lenses with focal lengths of 28mm and 40mm are also available.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
