Optical Surfaces manufactured the off-axis parabolic mirror with surface accuracy of better than lambda/15 P-V, surface quality of 20/10 scratch/dig and surface slope error of lambda/10/cm P-V. This, together with an ultra-smooth coated reference flat (315 mm diameter), have been produced from Zerodur™ as the main reflective and reference components, for a large flight test alignment collimator under construction in SIMERA Technology Group’s optical clean room. This will be the largest and most capable privately-owned facility for testing of airborne and spaceborne optics in South Africa.
The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in 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. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
