Product Description
Low Distortion High Resolution Endoscope Lens 4K Medical Imaging Optics
This low distortion high resolution endoscope lens is optimized for 4K medical imaging platforms that expose every optical flaw in the relay train. The rod lens design is MTF-optimized to hold contrast above 0.5 at 80 line pairs per millimeter, while barrel distortion is held under one percent across the field. For surgeons reading fine tissue structures on 4K monitors, the difference between a conventional endoscope lens and this high resolution version is immediately visible in edge sharpness and color fidelity.
The optical system combines low dispersion glass elements with precision ground rod sections to suppress chromatic aberration and field curvature. Each low distortion endoscope lens is aligned and tested on an interferometer, and a modulation transfer function report is included with production batches for medical device qualification. The design supports sensor formats from 1/3 inch to 1/1.8 inch, and the optical team can adapt the rod length and back focal length to match your camera module. For OEM programs targeting laparoscopic, arthroscopic, or ENT endoscope platforms, this 4K medical imaging lens provides the resolution headroom that next generation systems demand.

Product Q&A
Why is low distortion important in a 4K endoscope lens?
At 4K resolution, geometric distortion that was acceptable in HD systems becomes obvious and can mislead surgeons about the size and position of tissue. Holding barrel distortion under one percent keeps straight instrument edges straight on screen, which improves orientation and measurement confidence during procedures.
What MTF values can you guarantee?
Our production specification guarantees MTF above 0.5 at 80 line pairs per millimeter on axis, and above 0.3 at the field edge for the standard configuration. Custom designs can be optimized for different sensor pixel pitches and working distances, and we provide measured MTF data rather than calculated values only.
Can this lens be adapted to our existing camera module?
Yes. The optical design is modular: we adjust the rod length, back focal length, and clear aperture to match your sensor format and housing. Send us the camera module specification and mechanical envelope, and we will propose an adapted low distortion endoscope lens design with performance predictions.
What testing data is provided with production batches?
Each batch ships with an MTF measurement report, distortion measurement data, surface quality inspection records, and dimensional certificates. This documentation package is designed to support your medical device technical file and incoming inspection process.
