Product Description
C-Mount 12mm Fixed Focal Machine Vision Lens 12MP Manual Iris for Barcode Reading
12mm 12MP Fixed Focal Machine Vision Lens
The C1228-12M is a 12mm fixed focal machine vision lens engineered around a 12MP sensor platform for industrial imaging. Built for the 2/3" format, this machine vision lens pairs a F2.8 to F16 manual iris with a 0.1m to Infinity manual focus range, so integrators can lock exposure and depth of field directly on the line. The all-glass optical path is assembled and tested in our own clean workshop, and every unit ships with a serialised test record. For buyers who need repeatable barcode reading, the C-mount interface drops straight onto GigE, USB3 and Camera Link cameras without adapters.

Why Integrators Choose This Machine Vision Lens
- 12MP resolving power keeps fine features crisp across the whole 2/3" field
- Low TV distortion of -0.05% at 0.5m supports accurate measurement without software warping
- Manual iris and focus with locking screws hold settings through vibration
- Wide -20C to 70C operating window suits factory floors and non-climate-controlled cells
- Lead-free soldering and RoHS compliant glass and coatings support green procurement
- Compact 29 x 33.5mm metal barrel fits tight multi-camera stations
Product Questions and Answers
What does the 12MP rating mean for my inspection accuracy?
The optical design resolves 12 megapixels across the 2/3" image circle, so a single frame captures enough detail for defect detection and gauging without stacking multiple exposures.
Can this machine vision lens be used for Barcode Reading?
Yes. The 12mm focal length and low distortion of -0.05% at 0.5m make this lens a strong match for barcode and datamatrix reading on high speed packaging lines, and the C-mount thread fits the majority of industrial cameras.
Is the lens suitable for a 24/7 production environment?
The metal barrel, locked manual controls and -20C to 70C operating range are specified for continuous duty. Each C1228-12M is burned in and its focus verified before packing.
How is quality controlled before shipment?
Every lens passes a modulation transfer function (MTF) bench test, a distortion check, a coating inspection and a final visual audit. A batch test report is available on request so you can document supplier quality for your own audits.
Which cameras and accessories are compatible?
Any C-mount camera with a 2/3" or smaller sensor works directly. The M25.5 P=0.5mm filter thread accepts standard filters, and we can supply extension rings, adapters and custom mounts for OEM projects.
Behind every C1228-12M is a machine vision optics team that has supplied fixed focal machine vision lens ranges to system integrators, camera makers and OEM equipment builders across Europe, North America and Asia. We manufacture in-house, keep tolerances under statistical control and provide traceable test data, so engineers get the same optical performance from the first sample to the ten-thousandth unit. Tell us your sensor, working distance and field of view, and our application engineers will confirm the 12mm machine vision lens is the right fit or recommend the closest alternative from the 12MP series. Volume pricing, private labelling and custom coatings are available for qualified programmes.
