Coaxial Standard Telecentric Lens, 16.78μm

Product Overview

The PMS-LTC15-230C from POMEAS is a standard telecentric lens with built-in coaxial illumination path for high-precision dimensional measurement and visual inspection. With a TV distortion of only 0.02% and a resolution of 16.78 μm, it keeps magnification constant across the field of view, so dimensions can be measured directly on the image. The built-in beamsplitter works with a coaxial light to evenly illuminate reflective surfaces. C-Mount mount, sensors up to 1/1.8".

Key Features

• Telecentric design with 0.02% TV distortion for metrology-grade image geometry.
• 16.78 μm object-side resolution for fine-detail inspection.
• Built-in coaxial beamsplitter path; pair with a coaxial light for reflective surfaces.
• Depth of field that absorbs part-height variation on the line.
• Standard C-Mount mount, integrates with common industrial cameras.
• Supported sensors: 1/1.8". Customization available on request.

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 coaxial telecentric lens and why use one?

It combines a telecentric lens with a built-in beamsplitter: magnification stays constant while a coaxial light illuminates reflective surfaces along the optical axis, so dimensions do not shift with part position and glossy surfaces image evenly.

Which sensors does this model support?

This model supports sensors up to 1/1.8". 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 0.02%, 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.
