Photonics Dictionary

C-mount lens: A C-mount lens refers to a specific type of lens commonly used in machine vision, surveillance, microscopy, and other imaging applications. The "C-mount" designation refers to the standard interface or mounting system used for attaching the lens to a camera or imaging device. These lenses have a threaded mount with a 1-inch diameter (approximately 25.4 mm) and 32 threads per inch (C-mount thread), allowing for a secure and standardized connection.

Characteristics of C-mount lenses include:

Interchangeability: C-mount lenses are interchangeable, meaning they can be easily removed and replaced with other C-mount lenses without requiring specialized tools or adapters. This interchangeability facilitates flexibility in adjusting the focal length, aperture, or optical characteristics to suit specific imaging requirements.

Compact size: C-mount lenses are generally compact and lightweight, making them suitable for use in space-constrained environments or applications where portability is essential.

Compatibility: C-mount lenses are compatible with a wide range of cameras and imaging devices designed to accommodate C-mount optics. These devices often feature a C-mount lens mount or adapter ring for attaching the lens securely.

Versatility: C-mount lenses are available in various focal lengths, aperture sizes, and optical configurations to meet diverse imaging needs. They can be used for capturing wide-angle or telephoto views, macro photography, microscopy, and other specialized imaging tasks.

Cost-effective: C-mount lenses are generally more affordable compared to lenses with proprietary mounts or larger sensor formats, making them a cost-effective choice for many applications.

Standardization: The C-mount standardization ensures compatibility and interoperability among different C-mount lenses and imaging systems from various manufacturers, simplifying the selection and integration process for users.

C-mount lenses are widely used in industrial machine vision systems, security and surveillance cameras, medical imaging devices, microscopy setups, scientific research, and hobbyist photography. Their versatility, compactness, and standardized mounting make them a popular choice for a wide range of imaging applications.
