BiTelecentric lenses represent the core business for Opto Engineering®.  These products benefit from two decades of progressive Research & Development, resulting in a wide range of lenses for a diverse and ever-growing number of applications.
TC Series lenses are “Bi-Telecentric”, meaning that the light rays are parallel on both the camera side as well as the object side. This important feature renders BiTelecentric lenses ideal for applications such as measurement and gaging, as the parallel rays on the object side ensure uniform spatial accuracy across the field of view, and the parallel rays on the camera side ensure uniform image intensity.
To select a telecentric lens, it’s best to know the optical format, or more accurately, the photoactive area, of the image sensor in your camera.
The OptoEngineering TC Series lenses are grouped by the Image Circle (Photoactive Area Diagonal of area-scan sensor, or PhotoActive Length of Line Scan Sensor) in the TABS below.

TC12K Series BiTelecentric Lenses
Supports Large-Format Area and 12K and 16K Line Scan Cameras
62.4 mm Image Circle
TC12K series telecentric lenses are designed to fit high resolution line detector cameras, as well as large-format area-scan cameras. An image circle diameter larger than 62 mm combined with very high resolution makes the TC12K series ideal for 12k and 16k Line-Scan cameras. Flat panel display, solar cell and electronic board inspection are among the most common applications of these optics in the electronics industry; at the same time the optical specifications make them perfectly suitable to accurately measure large mechanical parts. In addition to the standard M72x0.75 mount, TC12K lenses can be equipped with other camera mounts at no additional cost ensuring wide compatibility with most common line scan cameras. |

TC4K Series Flat BiTelecentric LensesÂ
for Up to 2/3″ Cameras
Up to 11.0 mm Image Circle
TC4K Series lenses are ideal for measurement applications using line scan cameras with a detector size up to 28.7 mm (example: 4096 pixels with pixel size 7 μm).ÂDimensional constraints are often a major issue when designing image scanning systems where the sample or the camera itself must be moved: TC4K series is the Opto Engineering® solution for applications and machines with tight dimensional constrains. Compatible LTCL4K illuminators with matching flat design and dedicated accessories allow for optical combinations that fit most geometrical measurement configurations.ÂTC4K series feature a standard F or M42 mount to fit common line scan camera interfaces. Additional mounts are available upon request. Moreover, the lens-camera interface provides both fine detector phase adjustment and a precise focusing mechanism. Detector phase adjustment allows to precisely position the linear FOV at 90° from the object movement direction. |
