This TC Series C-Mount 0.138x Bi-Telecentric Lens from Opto Engineering is designed for use with matrix detectors from 1/3" up to 2/3", and can function as a key component in any measurement system powered by machine vision. This lens can take advantage of high-resolution detectors such as 5MP - 2/3", acquiring images with high fidelity and precision.
Opto Engineering's bi-telecentric design allows these optics to achieve pure telecentricity; no magnification change occurs when moving away or towards the subject, making this lens ideal for measurement applications of mechanical parts ranging from extruded aluminum profiles to tiny clock gears.
