Fixed Focal Lens – CCL12512MPR

CCL12512MPR 1/2.5″ 12mm 5-Megapixel M12 fixed focal lens with F1.8 aperture and 35° FOV for compact monitoring and embedded vision systems.

12mm 5MP M12 Fixed Focal Lens

This 12mm 5MP M12 lens is a compact fixed focal lens designed for imaging systems that require a narrower field of view and higher optical detail than standard wide-angle camera lenses. With a 12mm focal length, F1.8 aperture, 35° diagonal FOV on a 1/2.5″ sensor, and M12X0.5 mount, it provides a practical optical solution for targeted monitoring, embedded imaging, and compact vision systems.

M12 Fixed Focal Lens Applications & Compatible Devices

Targeted Monitoring and Observation

This 12 mm M12 lens features a narrower FOV than short‑focal alternatives. With a 35° diagonal FOV for 1/2.5″ sensors, it delivers detail‑focused targeted observation. Suitable for entrance, equipment and indoor security monitoring. Compatible with 1/2.5″, 1/2.7″ CMOS modules, compact IP and embedded vision systems.

For applications involving different sensor sizes, the Sensor Guide can help determine the appropriate lens and sensor combination.

Compact High-Resolution Imaging

With 5MP resolution and a 12mm focal length, this M12 fixed focal lens is suitable for compact imaging equipment where a higher-resolution sensor needs a more focused field of view. The fixed optical configuration simplifies lens selection for camera designs with a predetermined working distance and viewing area.

The 25.5mm T.T.L. and 8.3mm B.F.L. also make the lens suitable for compact optical assemblies where mechanical integration and available optical space need to be considered during camera development.

For projects requiring a customized optical configuration, TOWIN provides a range of M12 Lenses for different sensor formats, focal lengths, and imaging requirements.

Embedded Vision and Specialized Camera Systems

The F1.8 aperture and 5MP resolution make this lens a practical option for embedded camera systems requiring detailed imaging within a controlled field of view. Its manual focus and fixed iris configuration are suitable for camera designs where the optical setup can be adjusted during installation and then maintained at a fixed operating position.

Potential compatible equipment includes embedded vision modules, compact industrial cameras, smart monitoring terminals, inspection cameras, IoT imaging devices, and specialized camera modules.

Before selecting the final focal length, engineers can use the FOV Calculator to estimate the required field of view based on sensor dimensions, working distance, and target coverage. Additional optical considerations can be reviewed through the Lens Selection Guide.

Frequently Asked Questions

Q: What type of lens is the 12mm 5MP M12 lens?
A: It is a 12mm fixed focal M12 lens designed for compact imaging systems requiring a relatively narrow field of view and 5MP image resolution.

Q: What is the field of view of this 12mm M12 lens?
A: On a 1/2.5″ sensor, the lens provides 35° diagonal, 27° horizontal, and 20° vertical FOV. On a 1/2.7″ sensor, the specified FOV is 32° diagonal, 28° horizontal, and 16° vertical.
