Edmund Optics SilverTL™ telecentric lenses are high resolution lenses designed for industrial applications where precise measurement is essential. These C-mount telecentric lenses are widely used in production lines for inspection, measurement, gauging and image stitching tasks. SilverTL™ telecentric lenses are available in magnifications from 0.16X to 4X, resolutions up to 7.5 megapixels, and with inline illumination options. They are compatible with 1/2", 2/3", or 1/1.8" lens format sizes, and 2.8 µm pixel size sensors.
These telecentric lenses with inline illumination option are equipped with a front filter thread for accessories such as filters, polarizers, or ring lights to provide a wide range of lighting options. The inline illumination port can be rotated or repositioned for optimal illumination.
SilverTL™ telecentric lenses are built with Edmund Optics TECHSPEC® components for exceptional image quality and measurement accuracy. They are designed for industrial environments to withstand vibration. The locking set screw keeps the adjustable iris in place.

**During production Edmund Optics adds shims to the telecentric lenses in the c-mount to maximize performance. This can shift the working distance from nominal by as much as 3mm in either direction (though usually much much less).
