Product Overview
The PMS-LTC1-85 from POMEAS is a standard telecentric lens for high-precision dimensional measurement and visual inspection. With a TV distortion of only 0.002% and a resolution of 8.39 μm, it keeps magnification constant across the field of view, so dimensions can be measured directly on the image. C-Mount mount, sensors up to 2/3".
Key Features
- Telecentric design with 0.002% TV distortion for metrology-grade image geometry.
- 8.39 μm object-side resolution for fine-detail inspection.
- Depth of field that absorbs part-height variation on the line.
- Standard C-Mount mount, integrates with common industrial cameras.
- Supported sensors: 2/3". Customization available on request.

Selection Guide
To choose the right model, first compare the smallest feature to inspect with the lens resolution and the camera pixel size; then confirm the working distance available in the machine and the maximum supported sensor size. POMEAS can customize working distance, mount and magnification for your application.
Frequently Asked Questions
What is a telecentric lens and why use one?
A telecentric lens keeps magnification constant even when the working distance changes, so dimensions measured on the image do not shift with part position. It is the foundation of accurate optical metrology.
Which sensors does this model support?
This model supports sensors up to 2/3". Verify the mount and sensor size of your camera before final selection.
How much distortion does it introduce?
The TV distortion of this model is 0.002%, keeping image geometry stable from center to edge — a key requirement when dimensions are calculated directly from image coordinates.
Can the working distance or mount be customized?
Yes. POMEAS offers customization of working distance, mount and magnification; send your part and camera specifications so the technical team can confirm the solution.
