Preview of the official DFA5005A specification sheet — outer dimensions, flange-back, thread sizes and the complete parameter table.
The drawing below is the mechanical outline and specification table from the DFA5005A datasheet — use it to check the mount, flange distance and lens envelope against your housing before you order. Per-model MTF and distortion data is issued with the full datasheet and can be supplied as a signed test report.
Dimensional drawing and specification table — DFA5005A datasheet. Full-size PDF, 3D model and measured MTF / distortion test reports are available on request.
MTF is measured on an optical transfer function instrument covering 0–500 lp/mm (visible / NIR) and 0–60 lp/mm (LWIR), with on-axis accuracy better than ±2%.
TV distortion −0.3% Distortion is measured to better than 0.25% accuracy, so the figure in the datasheet is usable directly in your measurement model.
Production units can ship with a signed test report from our CMA / CNAS accredited optical testing center — specify the test items when you order.
PCB AOI, SMT placement, connector pins and character / 2D-code verification.
Wafer mark ID, lead-frame alignment and bonding inspection.
Springs, threads, seals and small turned parts at micron-level resolution.
Dimensioning, dynamic code reading and multi-height SKU capture.
A lens rarely fails on its own — it fails because the light, the camera interface or the mechanics were chosen in isolation. Here is what we recommend checking before you order.
Ring light for flat parts, coaxial for reflective surfaces, low-angle bar light for embossed features.
A C camera matched to the 2/3" sensor format.
Bandpass or polarising filter in the front thread to kill ambient light on the line.
C-mount extension tubes if you need a shorter working distance, plus a locking focus ring for vibration-prone stations.
