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.
