Sill Optics T

Telecentric lenses with a long working distance 

This telecentric lens series is specially designed for applications where a long working distance is required. The standard thread supplied is C-mount, but the lenses can be customised for other lens mounts.

The whole series has a clear aperture of 15 mm to 103 mm and a magnification range from 0.083x up to 4.0x. Some models are also available with coaxial illumination.  

Reasons to choose the T-Series

It's available with longer working distances

The Sill T-Series has been designed for applications where a working distance of up to 400 mm is required. This opens up the possibilities to work on high accuracy measurement applications that are slightly further away from the camera.

Some models are available with coaxial illumination 

Coaxial illumination provides homogeneous illumination across the object and having it integrated into the lens means the design is much more compact. By default, a polarised beam splitter is installed. Depending on the surface properties an un-polarised beam splitter may yield better results for extremely shiny surfaces.
