Product Overview

The PMS-LTCM0088-120 from POMEAS is a telecentric lens for high-precision dimensional measurement and visual inspection. With object telecentricity better than 0.04° and a depth of field of 16–45 mm, it keeps magnification constant across the field of view, so dimensions can be measured directly on the image without perspective error. C-Mount mount, sensors up to 2/3".

PMS-LTCM0088-120 0.088X High-Resolution Telecentric Lens, 120mm WD

PMS-LTCM0088-120 0.088X High-Resolution Telecentric Lens, 120mm WD - Specifications

Typical Applications

Dimensional measurement of machined and molded parts, electronics and connector inspection, glass and sheet-edge inspection, in-line quality control wherever telecentric geometry and stable magnification are required.

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 when should I use one?

A telecentric lens keeps magnification constant over its depth of field, so the part size does not change with position or height. Use it whenever dimensions are measured directly from the image: connector pins, machined features, stamped parts and glass edges.

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 -0.022%, 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.
