An article titled 'Unveiling the Cosmos' has been published by Optical Surfaces, which discusses the latest challenges and trends in modern astronomy and describes how these advances have acted as a significant driver towards the improvement of their optical technologies.

Using new high homogeneity optical materials and improved polishing compounds has enabled Optical Surfaces to make further improvements in their manufacturing of large space optics with very tight manufacturing tolerances. Combining this with the latest coating technologies the company is now able to deliver optical components with improved reflective / anti-reflective performance and enhanced environmental stability, protection and durability.

Benefiting from operating in a production environment, free from vibration and temperature variation, Optical Surfaces claims to be able to regularly produce high precision aspheric optics, ultra-smooth mirrors, high performance prisms, Schmidt camera and Laser launch telescope optics which stretch the limits of conventional optical fabrication techniques.

To certify the surface accuracy and precision of its astronomical optics, Optical Surfaces uses large aperture Zygo GPI, Twyman Green, Scatterplate, Fizeau and Laser Unequal Path (LUPI) interferometers which enables one-to-one testing of even the largest diameter astronomical optics. Topographic and fringe analysis provides precise testing of surface roughness and confirms the wavefront of various surface forms.
