Fixed Focal Lens – CCL12512MP

CCL12512MP 1/2.5″ 12mm 3-Megapixel M12 fixed focal lens with F1.6 aperture, 34° FOV and manual focus for compact embedded camera systems.

12mm 3MP M12 Fixed Focal Lens

This 12mm M12 fixed focal lens is designed for compact imaging systems using 1/2.5″ sensors, delivering 3MP resolution with a 34° diagonal field of view. Its F1.6 aperture provides efficient light transmission, while the M12 × 0.5 mount and compact optical configuration make it suitable for embedded camera modules and space-constrained vision devices.

With a 0.2m minimum object distance and manual focus adjustment, this lens offers practical flexibility when precise focus positioning is required during camera integration. For more options, explore TOWIN’s M12 Lenses.

Product Core Highlights

• 12mm fixed focal length for stable and consistent imaging
• 3MP resolution designed for 1/2.5″ sensor applications
• F1.6 aperture for efficient light collection in compact camera systems
• 34° diagonal FOV provides controlled scene coverage without an excessively wide perspective
• M12 × 0.5 mount supports compact embedded camera integration
• Manual focus with 0.2m M.O.D. provides installation-level focusing flexibility

Applications & Compatible Devices

The combination of a 12mm focal length, 34° diagonal FOV, F1.6 aperture, and manual focus makes this lens suitable for imaging applications that require controlled field coverage rather than ultra-wide viewing angles. The 0.2m minimum object distance also supports relatively close-range imaging after appropriate mechanical focusing during installation.

Typical applications include:

• Compact surveillance and monitoring camera modules
• Indoor security camera systems requiring a narrower viewing angle
• Embedded vision cameras
• Smart IoT imaging devices
• Access control and monitoring equipment
• Compact inspection and observation systems
• Fixed-position camera modules
• Small-format CMOS camera assemblies

Compatible devices may include 1/2.5″ CMOS camera modules, embedded cameras, compact security cameras, IoT vision devices, and other M12-mount imaging platforms where 3MP resolution and a 12mm focal length meet the system requirements.

When selecting an M12 lens, sensor format, focal length, field of view, working distance, and image resolution should be considered together. TOWIN’s Sensor Guide can help engineers understand sensor compatibility, while the Lens Selection Guide provides additional guidance for matching lenses to imaging requirements.

Why Choose This 12mm M12 Fixed Focal Lens?

This lens is particularly useful when a camera system needs a compact M12 interface with a moderate field of view and relatively large F1.6 aperture. Compared with ultra-wide M12 lenses, the 34° diagonal FOV provides more controlled scene framing, which can be advantageous for fixed-position monitoring and embedded imaging where excessive peripheral coverage is unnecessary.

The manual focus configuration also allows engineers to adjust focus according to the actual installation distance. With a 0.2m M.O.D., the lens can support relatively close imaging scenarios while maintaining a compact M12 form factor.
