Sill Optics tunable telecentric lenses

Telecentric lenses with a tunable working distance

Thanks to a cooperation between Sill and Optotune, you can dynamically adjust the working distance of telecentric lenses at a rate of up to 40 times per second.

The working distance on the configurations is linearly proportional to the dioptic power. Due to the influence of the focal length, the magnification is not constant. However, with some calibration adjustments, this small difference can be corrected for consistent accuracy (by adjusting it for the linear behaviour). Due to the telecentricity condition, the aperture of the system can be projected to infinity on the telecentric side.

In an optic side telecetric lens the tunable lens needs to be mounted behind the aperture of the lens (in front of the camera sensor) - please note that this configuration does not allow for the possibility of a bi-telecentric solution.
