ZnS & Ge Infrared Windows Specialties
Kenley, UK — Working with IR-transmitting materials including Zinc Sulphide and Germanium, Optical Surfaces is well known as a specialist developer of durable, high precision windows for protecting sensitive optics and sensors in aerial surveillance and reconnaissance applications.
Benefiting from a stable manufacturing environment and leveraging proprietary production techniques, Optical Surfaces Ltd. has become a leading supplier of large, high precision windows for a range of demanding applications.
Another Optical Surfaces speciality is the production of high quality, flexible windows (debris shields) that are commonly used in ultra-high power laser research establishments to protect critical optical components from ablated materials while maintaining optical performance in the beam line.
Manufacturing debris shields combines the dual demands of producing a precision wavefront (typically ?/5 to ?/10) on a flexible window with a high diameter to thickness ratio (e.g. 372 mm diameter and 10 mm thickness).
Working with a range of glasses, including BK-7 and fused silica, which offer good homogeneity and transmission from the UV to the Near-IR, Optical Surfaces Ltd. has also earned a reputation as a leading supplier of large, high precision laser windows.
The company’s skilled craftsmen are able to routinely produce high-power laser windows up to 600 mm in diameter with typical wavefront error of lambda/10 and surface finish of 40/20 to 10/5.
To optimise the performance of high-power lasers, Optical Surfaces Ltd is able to supply the latest dielectric coatings on windows to provide minimum pulse distortion, maximum usable bandwidth and durability.
Optical Surfaces Ltd has been producing optical components, mounted optical components and systems for more than 50 years and is now accepted as one of the world’s leading manufacturers of high-precision optics and optical systems. 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.
