The K1628-25M is a 16mm C-mount camera lens built for semiconductor and electronics metrology, where a straight image matters more than a wide one. With 25MP of resolving power across a 1.1-inch sensor and TV distortion of only -0.09% at 0.4m, the lens keeps grid structures, bond pads and fine tracks in their true positions, so inspection algorithms spend less time on geometric correction and more time on defect classification.
The 16mm focal length gives a 47.82 x 35.94 degree field on a 1.1-inch sensor, a working balance that fills a wafer field of view at a comfortable standoff. A F2.8 to F16 manual iris and a 0.15m to infinity focus ring are both lockable, and the anodised aluminium barrel carries an M40.5 P=0.5mm filter thread. Each 25MP camera lens is assembled in our own workshop and released with an MTF trace and distortion record, so a wafer surface inspection cell can be qualified from documented data rather than from a lucky sample.

A: Wafer inspection compares measured geometry against a known pattern. At -0.09% TV distortion the 16mm 25MP camera lens introduces only a fraction of a pixel of positional error across the field at 0.4m, so critical dimension and overlay checks stay inside tolerance.
A: Focus travel runs from 0.15m to infinity. Most wafer and PCB stations sit between 0.2m and 0.6m, where distortion is specified and the iris can be stopped down for depth of field.
A: Yes. The 25MP machine vision lens covers 1.1-inch, 1-inch, 1/1.2-inch, 2/3-inch and smaller formats. Field of view scales with sensor size, and the lens remains diffraction limited at F8 on smaller formats.
A: Coating adhesion and transmission are checked per batch on a spectrophotometer, and each 25MP C-mount lens is inspected under oblique light for sleeks, digs and coating voids before packing.
A: We provide MTF, distortion and visual inspection records with every shipment, plus first article inspection reports and PPAP style documentation on request for OEM and fab supplier qualification.
Our optics workshop produces fixed focal machine vision lens families for semiconductor, electronics and metrology customers in Europe, North America and Asia. Grinding, coating and assembly stay in house, and every 25MP camera lens leaves with measurable data attached. Tell us your sensor, field of view and defect size target, and our application engineers will confirm the K1628-25M or propose the closest focal length in the 25MP series. Volume pricing, private labelling and custom filter threads are available.
