Product Description
K2528-25M 25mm 25MP Compact Machine Vision Lens in a 35mm Barrel
The K2528-25M is a 25mm fixed focal machine vision lens that fits 25MP of resolution into a 35mm diameter, 42.8mm long barrel. That footprint matters on robot wrists, delta platforms and dense multi-camera cells, where a wide lens shroud blocks the light path or collides with a gripper. Despite the compact body, the lens covers a 1.1-inch image circle at 25 megapixels, so position and orientation data for robot guidance arrives from one clean frame.
Field of view is 31.68 x 23.45 degrees on a 1.1-inch sensor, a natural match for pick-and-place envelopes at 0.3m to 1m working distance. TV distortion is -0.07% at 0.4m, which keeps the coordinate transform between camera and robot stable across the whole field. The manual iris runs F2.8 to F16 with a locking screw, focus travels 0.15m to infinity, and the M30.5 P=0.5mm thread takes standard filters. Every unit is aligned and MTF tested in house before it ships with its own record.

Typical Applications
- Robot guidance, bin picking and pick-and-place positioning
- Assembly verification on compact cells with limited mounting space
- Vision guided cartesian and SCARA motion systems
- Code reading and part orientation on moving conveyors
- Small part gauging where a 25MP frame covers the full travel
- Multi-camera arrays that require a narrow barrel profile
Why This Compact 25mm 25MP Lens Works on Robot Wrists
- 35mm diameter barrel clears grippers and tool changers on robot wrists and delta platforms
- 25MP resolution across the 1.1-inch circle keeps small features readable at 0.3m to 1m
- -0.07% TV distortion at 0.4m stabilises camera-to-robot coordinate mapping
- Locked manual iris and focus survive repeated acceleration cycles without drift
- Aluminium anodised housing resists coolant mist and workshop contamination
- RoHS compliant materials and documented MTF traces support machine builder audits
Product Questions and Answers
Q: Will a 35mm barrel really fit my robot cell?
A: The K2528-25M measures 35mm in diameter and 42.8mm long, roughly half the volume of a typical 1.1-inch wide-angle lens. That lets the 25MP machine vision lens sit close to a gripper without shadowing the light or hitting the part.
Q: How stable is the camera-to-robot calibration with this lens?
A: With -0.07% TV distortion at 0.4m and locked iris and focus screws, the mapping between pixel coordinates and robot coordinates holds through a shift. Recalibration intervals in most cells stretch from weekly to monthly.
Q: Does 25MP resolution slow down my vision pipeline?
A: Frame rate depends on the camera and interface, not the lens. If throughput is the constraint, the sensor can be windowed or binned and the same 25MP machine vision lens still delivers a clean image on the reduced region.
Q: What lighting and filters work with this lens?
A: The M30.5 P=0.5mm front thread accepts bandpass, polarising and protective filters. For backlit positioning we recommend an F8 setting with a narrow bandpass filter matched to the light source wavelength.
Q: Can you tune the lens for my working distance?
A: Yes. Send your distance, field of view and sensor format and our engineers will confirm the 25mm 25MP machine vision lens or specify a different focal length from the series, with extension rings if needed.
Manufacturing and Customisation
We build fixed focal machine vision lens series for robot integrators, machine builders and camera manufacturers in Europe, North America and Asia, with grinding, coating and assembly kept in house. The K2528-25M was sized after repeated requests from integrators who needed 25MP imaging in a narrow barrel. Share your cell layout and field of view and our application team will confirm the fit, arrange samples and quote volume pricing, private labelling or custom filter threads.
