Fast Fixed Focal Length Lenses Provide High Resolution Imaging

Barrington, NJ — Edmund Optics (EO), a provider of optical components and tools, recently announced the availability of two new fast, fixed focal length lenses. The new TECHSPEC™ lenses offer object-space resolution better than two line-pairs per millimeter and are available in popular focal lengths such as 8.5 and 12mm. These lenses are designed for high-speed, high-resolution imaging, making them ideal for on-line inspection applications.

The high-resolution fixed focal length lenses support sensors as large as 2/3-inch and provide an angular field of view greater than 40º. At the lens' minimum working distance of 200mm, this 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, offering speeds as fast as f-1.3.

As with other TECHSPEC imaging lenses, the high-resolution fixed focal length 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. Focus and iris adjustments can be locked using thumb–screws, or replaced with setscrews to give a more permanent lock. Industry standard filters can be easily attached to these lenses via the M25.5 x 0.5-mm filter thread located on the front of the lens.
