Under Development Abakus Radiation-Tolerant Zoom

Abakus is developing a compact, radiation-tolerant zoom lens for 1/3” format cameras. It has been designed to withstand radiation levels of more than 106 Gray (108 Rad). Physically the system is mechanically rugged and can be expected to have a long life under normal operations.

The zoom range of 6 mm to 905 mm together with a close focus of only 1000 mm gives the wide field of view and the high magnification options needed by the industry. The image at wide angle has an impressive diagonal of 60°. Whereas for examining fine detail, such as a barcode, the smallest object to fill the field of view at close focus, is only 46 mm wide by 34 mm high.

Using Abakus specially-designed, radiation- tolerant, zoom and fixed-focal-length lenses, radioactive environments can be viewed efficiently, accurately and safely.
