Close inspection. Zero distortion. For high-speed inspections
These lenses are specifically designed to work naturally as macros, as opposed to infinite conjugate lenses with added spacers: a common alternative but unable to deliver the same optical performances.

MC4K lenses feature a fixed aperture, selected to ensure optimal field depth, image resolution and brightness for each magnification range, while meeting the typical needs of machine vision applications. The absence of an iris adjustment mechanism leads to a simpler and streamlined build, providing extra durability and precision.

Machine integration is made easy due to the precise focusing mechanism and the possibility to choose from an F or M42x1 mount (-N). Additionally, the series features a front M30.5x0.5 thread for easy insertion of an optional filter as well as easy phase adjustment.


Superior optical performance
Dimensional constraints are often a major issue when designing image scanning systems where the sample or the camera itself must be moved, and the TC4K series is the solution for applications and machines with tight dimensional constrains.

Fitting 4k linescan detectors up to 28.7 mm such as 4096 px with pixel size 7 µm, the TC4K lenses are available for 60, 90, 120, 180 mm fields of view and are suitable for F or M42x1 camera mount.

TC4K series feature standard F or M42 mount to fit common linescan camera interfaces with additional mounts available upon request.

The lens-camera interface provides both fine detector phase adjustment and a precise focusing mechanism. Detector phase adjustment allows to position, precisely, the linear FOV at 90° from the object movement direction.

Key advantages

Macro design
Achieve unmatched resolution in critical applications: these objectives consistently deliver superior image quality than standard fixed focal length lenses used with extension tubes
Specially-designed illumination
Machine vision systems that utilise telecentric lens require a lighting method that complements these precision optics. LTCL4K telecentric illuminators provide the high optical throughput needed for high-speed linescan measurement applications. More...
Exceptional low distortion
Perform measurement tasks with a high degree of accuracy and reliability.
Compact design
“Flat” shape for easy integration
Optimized aperture
For each magnification, the f/# is optimized to ensure the best field depth and image resolution
Dedicated CMMR4K mirrors
90° deflection of the light path for usage in tight spaces and easy integration
Easy front filter insertion
Thanks to the front M30.5x0.5 thread
Easy rotational phase and focus adjustment
Robust and precise tuning of FOV phase angle and best focus position


LTCL4K telecentric illuminators are specifically designed to be paired with TC4K telecentric lenses, in order to provide the high optical throughput needed for high-speed linescan measurement applications.

State-of-the-art LED driving electronics provide exceptional illumination stability, precise light intensity tuning and easy replacement of the LED source.

The unique “slim” form factor allows these units to be used in constrained spaces. CMMR deflecting mirror accessories can be integrated to assemble different illumination geometries quickly, and are compatible with most types of inspection configurations.
