Large diameter lens for shielded camera

Camera sensor size is one the most important factors in determining overall camera performance and image quality. A key advantage of 1” sensors is that they are larger than most sensors found in nuclear cameras, which allows them to capture more light and produce higher image quality. The new Model 408-000 demonstrates Resolve Optics proven ability to modify and adapt one of their existing radiation resistant lens designs to meet a customer’s specific requirements.

Mark Pontin, Managing Director of Resolve Optics, commented: “By scaling-up the optical and mechanical design of our popular Model 192 lens we were able to create a 6x Non-Browning Zoom Lens optimally matched to the large 1” image format and providing the range of FOVs required by the customer.  By adapting an existing design – we were able to significantly reduce the overall lead time to supply the first batch of lenses.”

The Model 408-000 non-browning 6x zoom lens offers high performance over an extended 24-144mm focal length range making it perfect for remote monitoring tasks in nuclear reprocessing and power plants. The Model 408-000 speciality glass components can withstand long-term exposure to radiation, up to a dose of 100 million RAD and without loss of transmission and minimal colour change. Operating at f/3.6, the Model 408-000 provides good image resolution and minimum geometric distortion from 400 to 750nm. When focused at infinity, the Model 408-000 will maintain focus throughout the zoom range without the need to refocus.
