Schneider Optics’ C-mount 2/3 in. (11-m image circle) lenses are designed for aerospace and military imaging. The compact precision primes are optically corrected and broadband-coated for the visible and near-infrared spectral range of 400 to 1000 nm on megapixel cameras. Engineered to image properly across the entire specified range, they offer consistent operation without focus shifts. Providing high vibration stability, they feature a robust yet lightweight mechanical design. A lockable-focus and iris-setting mechanism guarantees long-term stability, even in rigorous production environments. The lens family includes the following focal lengths: 4.8, 6, 8, 12, 17, 23, 35 and 70 mm. Most have front threads to accept a screw-on filter, except for the 4.8- and 6-mm lenses, which have a filter adapter.
