  • Resolve Supplies Lenses for NASA Testing

Jun 2014
CHESHAM, England, June 27, 2014 — Resolve Optics has supplied non-browning zoom lenses to NASA for the study of future low-maintenance space-based optics.

Space presents a challenging environment where camera lens servicing or replacement is highly undesirable, the company said. The company’s radiation-tolerant lenses are made from cerium oxide-doped glass and synthetic silica, allowing them to withstand radiation doses of up to 100 million rads and temperatures up to 55 °C without discoloration or degradation of performance.

The non-browning lenses provide high image resolution and minimum geometric distortion from 400 to 750 nm.

The lenses will be used at the Satellite Servicing Capabilities Office at NASA’s Goddard Space Flight Center in Greenbelt, Md. The center investigates human and robotic satellite servicing, and develops technologies for orbital spacecraft inspection, repair, refueling, component replacement and assembly.

GLOSSARY
camera
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
degradation
The gradual decrease over time in output signal with constant input light level.
