The M8513 from Computar is a 2/3-inch design, manual iris C-Mount 8.5mm focal point with an opening scope of 1.3-16C. Utilized on a 2/3-inch camera, it gives a wide point even perspective on 57.4 degrees.

Monofocal focal points are a prudent decision giving fixed central lengths from very wide edge to fax contingent upon the camera group and expected application. All are C-Mount, included all glass optics, accompany locking setscrews and a solid metal barrel and mount.
