Radiation resistant lens
Resolve Optics, a supplier ofradiotherapy equipment, has developed a 24mm diameter fixed focus non-browning lens to a market leader in radiotherapy equipment. The company sought a high resolution lens able to withstand and focus the high levels of radiation produced by its synchrotron device onto tumours.
Using cerium-doped glasses, Resolve Optics produced a compact f/2.8 lens able to withstand long-term exposure to radiation up to a dose of 100 million radians without discolouration. This new lens is enabling customers to improve the precision radiotherapy treatment of tumours that its equipment provides.
