Fast fixed focal length lenses provide high resolution imaging.
TECHSPEC fast fixed focal length lenses offer object-space resolution better than two line-pairs per millimeter and are available in popular focal lengths such as 8.5 and 12 mm. The lenses are suited for high-speed, high-resolution imaging, making them suitable for online inspection applications. The lenses support sensors as large as 2/3" and provide an angular field of view greater than 40[degrees]. The minimum working distance is 200 mm, which corresponds to a field 240 mm wide for the 8.5-mm focal length lens (#58-000) and 155 mm for the 12-mm focal length lens (#58-001). The short focal lengths of these macro lenses allow them to work in low-lighting applications. Edmund Optics www.edmundoptics.com, 800-363-1992
