Resolve Optics, a leading OEM designer and supplier specializing in high-performance optical systems for satellite data relay, has addressed the critical requirements for optical lenses used in space operations. Mark Pontin, Managing Director of Resolve Optics, highlighted the growing demand for advanced satellite data relay systems driven by the increasing international need for data and telecommunications.
Pontin emphasized the significant role of radiation tolerance in space-based optics. He explained that satellite data relay systems operating in Earth orbit encounter varying levels of radiation, which directly impacts the optical components. To combat this, Resolve Optics utilizes specialized radiation-tolerant designs incorporating cerium oxide doped glass or synthetic silica. This approach allows their lenses to withstand substantial radiation doses, up to 100,000,000 rads, and temperatures reaching 55°C without performance degradation or discoloration, maintaining high image resolution and minimal geometric distortion across the 400 to 750 nm spectrum.
Addressing a frequent inquiry about the necessity of radiation-tolerant lenses for space applications, Resolve Optics clarified that cosmic radiation poses a considerable challenge to standard optical glass. Exposure to radiation can cause conventional glass to discolor, leading to a significant reduction in light transmission and impaired lens performance. While standard glass might suffice for short missions, longer space endeavors necessitate the use of specialized, radiation-tolerant glass like cerium doped glass to ensure continued optical performance.
Beyond radiation resistance, optics intended for satellite data relay systems must also endure the harsh space environment. These systems are constructed from materials selected to prevent outgassing in the vacuum of space. Furthermore, any significant airspaces within the optical system are vented to prevent pressure build-up and distortion of the optical elements.
With nearly three decades of experience, Resolve Optics has established itself as a reputable specialist in designing and manufacturing high-performance precision lenses and optical products for smaller production runs, consistently meeting stringent quality standards, timelines, and budget targets. Their expertise in providing radiation-resistant optical systems for spaceborne projects is widely recognized within the industry.
