Product Overview

The PMS-LTC1-65 is a compact standard telecentric lens built for high-precision dimensional inspection of small parts. With a slim Φ16 mm barrel, 10 μm resolution and TV distortion as low as 0.01%, it keeps magnification constant across the field of view, so edge positions and dimensions can be measured directly and reliably from the image. The lens supports sensors up to 1/2” and mounts on standard C-Mount industrial cameras.

PMS-LTC1-65 specifications and FOV table

Typical Applications

The PMS-LTC1-65 is aimed at precision size and position inspection where space is limited but measurement stability matters:

Dimensional inspection of small turned, stamped and molded parts.
Pin-pitch, gap and coplanarity checks on electronic assemblies.
Thread and edge-position verification on automated lines.
Compact multi-camera stations built around 1/2” sensors.

Selection Notes

Choose the PMS-LTC1-65 when your smallest critical feature needs about 10 μm resolution or better and the working station cannot accommodate a larger-barrel telecentric lens. Match the sensor size to the FOV table above (up to 6.4 × 4.8 mm on 1/2”), and verify that the 1.1 mm depth of field covers your part-height tolerance. If you need a larger field of view, consider the LTC2-150 2.0x model or the 55 mm LEH-5528M in the same family.

Frequently Asked Questions

What is the resolution of the PMS-LTC1-65?

The PMS-LTC1-65 delivers a 10 μm object-side resolution, sufficient for detecting fine features such as pin gaps, edge burrs and small dimensional deviations on precision parts.

Which camera sensor sizes does it support?

It supports sensors up to 1/2". The field of view is 3.2 × 2.4 mm on a 1/4" sensor, 4.8 × 3.6 mm on 1/3" and 6.4 × 4.8 mm on 1/2".

How much distortion does it introduce?

TV distortion is only 0.01%, so the image keeps a stable magnification across the field — a key requirement when measurements are calculated directly from image coordinates.

What is the depth of field?

At 1x magnification the depth of field is 1.1 mm, which keeps parts in focus even with small mounting-height variations on the production line.

Which optical parameters define its light collection?

The lens works at F No. 14.29 (aperture) with a numerical aperture of 0.04, matching the compact Φ16 mm barrel design.

Which lens mount does it use?

It uses a standard C-Mount and pairs directly with industrial area-scan cameras.

What working temperature range is supported?

The lens operates from about 10°C up to +50°C, covering typical factory-floor conditions.

Can the lens be customized?

Yes. Customization is supported according to customer requirements — for example adapting mount options or integration dimensions for specific production equipment.
