Precision Machine Vision 16mm Fixed Focal Lens 12MP C-Mount for PCB Inspection

The C1628-12M is a 16mm 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 PCB inspection, the C-mount interface drops straight onto GigE, USB3 and Camera Link cameras without adapters.

• PCB Inspection and automated optical inspection on high speed production lines
• Machine vision gauging, positioning and robot guidance systems
• Packaging, labelling and barcode verification equipment
• Electronics, semiconductor and PCB assembly quality control
• Food, pharmaceutical and agricultural optical sorting machines
• Document scanning and industrial measurement instruments

• 12MP resolving power keeps fine features crisp across the whole 2/3" field
• Low TV distortion of -0.02% 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 34.5mm metal barrel fits tight multi-camera stations

A: 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.

A: Yes. The 16mm focal length and low distortion of -0.02% at 0.5m make this lens a strong match for printed circuit board (PCB) solder joint and pad inspection, and the C-mount thread fits the majority of industrial cameras.

A: The metal barrel, locked manual controls and -20C to 70C operating range are specified for continuous duty. Each C1628-12M is burned in and its focus verified before packing.

A: 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.

A: 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 C1628-12M 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 16mm 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.
