DTCM125 Telecentric Machine Vision Lenses

COOLENS DTCM430H Bi-Telecentric Lenses for 4/3" Sensors

The COOLENS DTCM430H series consists of 20 bi-telecentric machine vision lenses for industrial cameras with sensors up to 4/3" and a maximum sensor diagonal of 23.6 mm. These lenses are designed for precise dimensional measurements and industrial inspection applications requiring constant magnification, low optical distortion and accurate edge detection.

The bi-telecentric optical design reduces perspective errors caused by small changes in object distance. Optical distortion is specified below 0.1%, while telecentricity is below 0.1°. This makes the lenses suitable for diameter and width measurements, contour inspection and accurate component positioning.

 

Field of view, magnification and working distance

The DTCM430H series offers object-side FOV diagonals from 26 to 300 mm, with optical magnifications ranging from 0.908x to 0.079x. Nominal working distances range from 73 to 465 mm. The large sensor coverage makes these lenses suitable for industrial cameras requiring a larger imaging area or high resolution.

 

Camera mount and mechanical installation

According to the catalogue, DTCM430H lenses are available with M42/M58 camera mounts. The correct mount must be verified for the selected configuration. Lens weight varies significantly, from approximately 0.8 to 47 kg. Larger models require rigid, independent mechanical support to prevent deflection and vibration.
