Online — Optical Surfaces Ltd. has received an order from Surrey Satellite Technology Ltd. (SSTL) for two high precision reference mirrors to accelerate the precise alignment and testing of their Earth Observation Satellite Telescopes.

Based in Guildford, UK, Surrey Satellite Technology Limited (SSTL) manufacture and operate small to medium sized satellites, covering a range of use cases, from telecoms to Earth observation.

Earth observation (EO) satellites are a core product for SSTL and each EO satellite undergo a rigorous process of testing and verification before and after launch.

As SSTL’s business has grown it required additional high precision reference mirrors to enable testing of its telescope optical systems in parallel.

Dr Aris Kouris, Sales Director at Optical Surfaces Ltd said, “We are pleased to have been entrusted once again by SSTL to deliver two demanding mounted reference flat mirrors for the purposes of verifying the wavefront performance of their EO telescopes during their assembly and as an alignment aid”.

Dr Kouris added, “I can definitely say that we are extremely pleased with the outcome and being able to assist SSTL with their challenging alignment and testing requirements”.

Dr Robin Cole, Optical Systems Engineer at SSTL, commented, “There are very few suppliers who can produce such large optics with the specifications we required”.
