With recent advances in technology – CMOS sensors are being developed capable of withstanding higher levels of radiation than was previously possible making them a viable option for a much larger range of nuclear application. In order to take advantage of the higher resolution colour images provided by a CMOS sensor, more and more nuclear camera manufactures are looking to use them as an alternative to traditional tubes. As a result – Resolve Optics has noted a growing demand for custom non-browning lenses optimised for the large variety of different formats that CMOS sensors are produced in.
Rob Watkinson, sales manager at Resolve Optics, said: “To fulfil this demand from different manufacturers of radiation tolerant, colour CMOS cameras we developed a 10x non-browning zoom lens design to provide better HD colour images for nuclear applications. To date we have produced versions of this non-browning lens optimized for ¼-inch, 1/3-inch and 2/3-inch CMOS sensor formats”.
He added ”Our HD zoom lens design uses non-browning glasses, specially selected to produce clear sharp images free of the strong yellow tint that has traditionally been a limiting issue when using non browning lenses on colour sensors. The glass used in these lenses can withstand long-term exposure to radiation up to an accumulative dose of one hundred million rad and temperatures up to 85 °C without transmission loss. All Resolve Optics non-browning lenses provide high image resolution and minimum geometric distortion from 400 to 750 nm”.
