Resolve Optics contracted to design and supply broadband lens for Lunar Rover microscope – SatNews

Broad band lens for lunar rover microscope

To achieve this demanding specification, in the harsh lunar landscape, the lens had to be heavily color corrected to the point that the design is nearly diffraction limited.

Resolve Optics received an order from a leading aerospace company to design and supply an optimized broadband lens for a multispectral microscope required for a lunar exploration mission.

Equipped with a magnetometer and microscopic camera, the solar-powered rover will leave the Lunar Vertex lander to explore up to 1.2 miles (2 kilometers) through Reiner Gamma, traversing light and dark soils and sampling magnetic properties of one of nature’s most distinctive characteristics. The rover is about 35 centimeters tall. The cylinder on top is the magnetometer mast built by APL.

Scheduled for delivery and launch in 2024 – a new solar-powered land rover – “Lunar Vertex” will explore the Reiner Gamma Vortex, one of the most distinctive natural features and so-called “magnetic anomalies” on the Moon. The mission will conduct follow-up surveys from both the lander and the rover which will explore just over a mile (up to 2 kilometers) of the 43-mile (70 kilometer) wide surface feature. The Lunar Vertex payload includes an ion-electron plasma spectrometer and cameras that will remain on the lander, magnetometers on the lander and rover, and a multispectral microscope on the rover.

Lens developed for the Lunar Vertex multispectral microscope

Mark Pontin, Managing Director of Resolve Optics commented, “We are delighted to have been selected as the supplier partner for this prestigious project. The Lunar Vertex rover’s multispectral microscope will use an array of light-emitting diodes (LEDs) to provide broadband (365 – 1000 nm) illumination of sections of the moon’s surface. The objective required for the microscope has been designed to provide the best possible transmission over this wide spectral bandwidth and maintain the best possible focus throughout. To achieve this demanding specification, in the harsh lunar landscape, the lens had to be heavily color corrected to the point that the design is nearly diffraction limited. The optical performance of this specialized microscope objective is further enhanced by custom-designed MLAR coatings on the glass elements.

“To add to the complexity of the design, the lens also needed to be athermalized to ensure its performance is maintained over the wide temperature range the microscope will encounter on the lunar surface. All components of our new lens for the Lunar Vertex Multispectral Microscope are manufactured from materials approved by international space agencies enabling Resolve Optics to provide Canadensys with a space-ready product.
