The novel design of the Model 290 provides a 6x zoom movement in a very compact form. This enables the lens to image objects from 800mm to infinity without using add-on adapters. When focused at infinity the lens achieves high image resolution on axis at full aperture throughout the zoom range without refocusing. The Model 290 provides high image resolution and minimum geometric distortion from 400 – 750nm.
All optical elements within Resolve Optics radiation resistant (non-browning) lens designs are made using cerium oxide doped glass or synthetic silica enabling them to withstand radiation doses of up to 100,000,000 rads and temperatures up to 55°C without discoloration or degradation of performance. All Resolve Optics radiation resistant lenses provide high image resolution and minimum geometric distortion from 400 to 750nm.
