Fixed-focal-length lenses provide high resolution

TECHSPEC lenses offer object-space resolution better than 2 lp/mm and are available in focal lengths such as 8.5 and 12 mm. The high-resolution fixed-focal-length lenses support sensors as large as 2/3 in. and provide an angular field of view greater than 40°. TECHSPEC imaging lenses offer a robust set of mechanics to complement the high-quality optics. Features include a low-profile housing, variable focus and iris adjustments with detents, and a standard C-mount interface for convenient camera coupling.
