Sill Optics has developed a 2.0x telecentric lens for 20MP sensors with sensor diagonal 21.4mm (1.25”) and pixel size up to 2.74µm, and free working distance 68.1mm. The 2.0x C-mount lens starts a series of standard products with the further factors 1.5x, 2.5x and 3.0x. Intermediate increments in 0.1 steps can also be realized as inquiry lenses. In addition, Sill Optics offers a version with an integrated liquid lens from Optotune, which enables a working distance change of 6mm within a few milliseconds. Via the focus adjustment, a Z-axis measurement is thus also possible.
