Double-sided telecentric lens for 4/3" sensors

28 Feb 2012

Sill Optics present a new double-sided telecentric lens with a magnification of 0.77x for 4/3" sensors.

The new lens with the part number SILL TZM 3208/0,77 complements the existing series of Sill lenses for 4/3" sensors, and is ideally suited for operation in combination with large-sensor cameras. The SILL TZM 3208/0,77 has a C-mount thread which can be modified for cameras with M42 when complying with a flange focal length of less than 17.52mm. The lens therefore is the ideal match for use in combination with the Teledyne DALSA Falcon2 or Vieworks VC- 4MC-M/C-180EO-C cameras.

The newly designed lens offers a distortion of less than 0.05% and a working distance of 119.6mm. The SILL?TZM?3208/0,77 features a fixed iris, and its high resolution can resolve pixel sizes down to 3.45µm. So the new double- sided telecentric lens SILL TZM 3208/0,77 is predestined for measurement tasks with high resolutions and for operation on large-sensor cameras.

Sill Optics also complemented further lens series. The telecentric Compact Series lens SILL TZM 2599/0,4 gained a new model with an effective length of only 148.5mm and a magnification of 0.392x. Just like the other correctals of this series it offers a very short working distance of only 92mm, however it is suitable for 1" chips with a minimum pixel size of 4.6µm.

Sill Optics present yet another Correctal Series T85 telecentric lens – the SILL TZM 6041/0,1. It provides a clear aperture of 86mm and an effective length of 275.5mm. The new lens with a magnification of 0.195x and a working distance of 180mm fits perfectly into the series. It is designed specifically for 2/3" chips with a maximum pixel size of 3.45µm. Both telecentric lenses offer a C-mount thread, a variable iris and are also available with integrated coaxial light input.
