Applications & Markets of the CITRINE lenses

Mounts for the CITRINE lenses

C-Mount

A C-mount is a specific mechanical connection widely used in the industry for cameras and lenses. It is defined by a diameter of 1 inch (25.4 mm) and 32 threads per inch (C-mount thread). This mount allows lenses to be easily and securely attached to cameras and is widely used in machine vision and other applications.

C-mount connectors provide a robust and proven solution for connecting lenses to cameras. The standardization of C-mount also makes it easy to change lenses to meet the changing needs of different applications.
