TCSE series hi-res telecentric lenses

Opto Engineering is known and respected for high-performance lenses in machine vision, medical, and related fields. The new TCSE series are telecentric lenses designed for large sensor formats (4/3″, APS-C, APS-H). Each provides high resolution with low distortion.

Who needs a telecentric lens?

Before inviting you to some of the TCSE series features, let’s offer readers who aren’t already telecentric-savvy a brief motivation for this category of lens. If you are doing precise gauging applications – measuring via optics and software – your tolerances may require a telecentric lens. A telecentric lens eliminates perspective error. They have very low distortion. And, if paired with collimated light, they enhance edge definition.

TCSE lenses are available for applications using light in either the visible spectrum or near-infrared (NIR) wavelengths. Currently there are 8 members in the TCSE product family.

Image circle diameter

The TCSE Series offers image circle diameter options from 24 – 45mm.


A key parameter in telecentric imaging is the level of magnification available. The 8 members of the TCSE Series offer magnification ranging from 0.36 through 2.75 times the original object size.

Working distance

The working distance (WD), from the front of the lens to the object being imaged, varies by lens model across the TCSE Series. The shortest WD offered is 160mm, spanning distances up to 240mm. These long working distances allow space for lighting and/or robotic arms.

Worth noting

While typically “plug and play” once mounted on your camera, it’s worth noting that the TCSE lenses offer back focal length adjustment, should one choose to fine tune.
