C-Mount Wide Angle Lens Applications

Core Application Scenes

This 5mm 850nm C-Mount lens is designed for imaging systems that need to combine a broad field of view with wavelength-specific near-infrared imaging. Its 95° diagonal FOV allows a single camera to observe a relatively large area, while the integrated 850nm band-pass filter helps restrict incoming optical energy to the specified near-infrared wavelength region.

In machine vision and industrial inspection, the lens can be used where 850nm illumination is intentionally introduced to enhance the contrast of selected materials, surfaces, markings, or objects. The short 5mm focal length is particularly useful when the camera needs to cover a large inspection zone from a relatively compact installation position.

The 0.1m minimum object distance provides additional flexibility for close-range imaging. This can be useful for compact inspection equipment, embedded vision modules, and systems where the camera must be positioned close to the monitored area while maintaining broad scene coverage.

The 850nm band-pass filter also makes the lens suitable for specialized NIR imaging setups in which ambient visible light needs to be reduced and a controlled 850nm illumination source is used. The actual optical response of the complete camera system will depend on the image sensor, illumination source, filter characteristics, and exposure settings.

For systems where the required field of view needs to be evaluated according to sensor size and working distance, the FOV Calculator can help estimate the expected image coverage.

Frequently Asked Questions

Q: What sensor size is this 5mm C-Mount lens designed for?
A: The lens is specified for a 2/3″ image format and provides the stated 95°/82°/67° FOV configuration for this sensor size.

Q: What is the field of view of this wide angle lens?
A: The lens provides a 95° diagonal, 82° horizontal, and 67° vertical FOV, making it suitable for broad-area imaging.

Q: What is the purpose of the 850nm band-pass filter?
A: The integrated 850nm band-pass filter is designed to transmit a selected near-infrared wavelength region around 850nm while reducing unwanted wavelengths. It is useful in imaging systems using controlled 850nm illumination.

Q: Is this lens an IR corrected lens?
A: Not based on the supplied specifications. The lens carries an 850 nm band‑pass filter, yet this feature alone does not make the optical system IR‑corrected. Confirm IR correction separately whenever your application demands it.

Q: Is the 5mm focal length fixed?
A: Specifications state 5 mm focal length for this wide‑angle lens. Classified as fixed‑focal lens; verify manufacturer mechanical specs to check for manual zoom capability.

Q: Is this lens suitable for close-range imaging?
A: Yes. Its 0.1m M.O.D. allows close-range imaging and can be useful for compact machine vision and inspection installations.

Q: What resolution does this C-Mount lens support?
A: The specified resolution is 5MP, making it suitable for a range of industrial and machine vision cameras requiring detailed image capture.

Q: Can this lens be used with 850nm LED illumination?
A: Yes. The integrated 850nm band-pass filter makes it particularly suitable for systems designed around 850nm illumination, provided that the camera sensor has adequate sensitivity at the selected wavelength.
