Optical Surfaces Ltd, through its local distributor Jeewoo Photonics Ltd, has been selected to supply a mounted 600 millimetre (mm) diameter off-axis parabolic mirror to the Samsung Thales R&D Centre in Gyeonggi-do, South Korea. The high-precision (surface-accuracy lambda [λ] /20) off-axis parabolic mirror will be used by Samsung’s optical system design team as a universal collimator system for the testing of large visible and infrared (IR) optics being developed for use in the next generation of Optical Surfaces’ thermal-imaging and electro-optical systems.
Samsung Thales is a high-tech optical company in Korea with more than 30 years of experience. The company has a product portfolio that ranges from small optical systems to large-aperture cameras, such as thermal-imaging cameras, airborne cameras for surveillance and reconnaissance and large-aperture satellite cameras. Samsung Thales has a facility to assemble and align large-aperture optical systems and collaborates with professional subcontractors manufacturing large-aperture mirrors and reference-flat mirrors from 500mm to 2 metres (m) in diameter.
Optical Surfaces’ International Organisation for Standardisation (ISO) 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated from solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions, testing, particularly with long path lengths, becomes quantifiable and reliable, according to the company.
