As the market leader in radiation resistant optical systems - all lenses are manufactured to the highest standards of quality and performance and are designed to withstand a total radiation dose of 100 million radians and temperatures to 55 °C without discoloration.
Suitable for use in nuclear fuel handling operation, reactor active zones and radioactive waste storage plants, the Model 290 motorised non-browning zoom lens is a direct replacement for the Fujinon 12-72 mm (6x) non browning zoom lens, which is no longer manufactured. All functions of the Model 290 are motorised and include slip clutches and electronic noise suppression. Operating at f/1.8 the Model 290 provides high image resolution and minimum geometric distortion from 400-750 nm. This versatile zoom lens can be used with single chip 1/2" and 2/3" CCTV cameras as well as Newvicon and Chalnicon tubes.
The Model 200 is an extremely compact 3x non-browning zoom lens. Operating at f /2.8 the Model 200 provides high image resolution, a close focus of 50 mm and minimum geometric distortion from 400-750 nm. Special cerium doped glass is used in Model 200 zoom lenses to avoid browning or discoloration when exposed to radiation.
The Model 192 is a compact non-browning 6× zoom lens proven in applications requiring radiation resistance including medicine, academia, space exploration and nuclear power generation plants. Operating at f/1.8, the Model 192 provides high image resolution and minimum geometric distortion from 400 to 750 nm, and it can image objects from 800 mm to infinity without the use of add-on adapters. When focused at infinity, the Model 192 achieves high image resolution on-axis at full aperture throughout the zoom range without refocusing (image tracking). The lens is designed for use with CCTV cameras, and with Newvicon and Chalnicon tubes.
The Model 357 is a new generation non-browning 10x zoom lens uniquely able to produce clear, sharp images free of the strong yellow tint that has traditionally been a limiting issue when using radiation resistant lenses on color sensors. Operating at f/3.6, the 2/3-inch format Model 357 provides high image resolution and minimum geometric distortion from 400 to 770 nm, and can image objects from 1.5 m to infinity without using add-on adapters. When focused at infinity, the lens achieves high image resolution at full aperture throughout the zoom range without refocusing.
In keeping with Resolve Optics tradition of designing application optimised lenses the company is also able to provide non-browning zoom or fixed focus lenses to meet your exact specification.
