The company can also replicate low CTE materials for off-axis-parabolic, ellipsoidal and freeform mirrors for space borne telescopes and space optical interconnect systems. Thorlabs is a manufacturer of scientific instruments, including a range of optical mirrors for use in telescopes. The company offers various coatings, sizes, and shapes of mirrors, including dielectric, aluminium, and gold coated. It also offers lenses made from various materials such as glass, sapphire, and silicon; as well as lenses with different shapes and sizes.
SPECTRUM SCIENTIFIC FEATURED PRODUCT
Optical replication allows the creation of high-specification mirrors and gratings for space and astronomy applications. SSI has supplied a number of ultra-low stray light gratings for
a number of high-profile projects, including the Orbiting Carbon Observatory (OCO) and Ozone Mapping Profiler Suite (OMPS), where we achieved an absolute diffraction efficiency of 74% at 250nm – which is within a few percent of the theoretical maximum – and exceptional stray light performance with energy levels reducing to less than 1x10E-6 1x10E-8
a few nanometres away from the first order and below between orders. SSI has also manufactured fast-focusing concave mirrors for
NASA’s Jet Propulsion Laboratory, which required high-performance UV mirrors on aluminium substrates. For this application the company achieved a surface figure of less than λ/80 RMS at 632.8nm and surface roughness on the order of 7Å. The final overcoat was aluminium with reflectivity at 200nm exceeding 90%.
