Optical Surfaces Ltd. is a leading producer of high precision mirrors and windows for Schlieren imaging applications in the Aerospace industry. Supersonic wind tunnels are commonly used by engineers to test and improve the aerodynamic performance of aircraft designs and engine components. During a test, the aircraft model is placed in the test sec Read More

Resolve Optics has written a white paper which discusses the key considerations when selecting a lens to get optimum performance from your camera or sensor. The ability of a lens to resolve detail is not only determined by its quality but also is ultimately limited by diffraction. It is commonly thought that the resolution of a lens should match o Read More

Resolve Optics is a leading supplier of application optimized relay lenses that improve the efficiency of image intensifiers. An image intensifier is a device for increasing the intensity of available light in an optical system to allow use under low-light conditions, to facilitate visual imaging of low-light processes, to convert non-visible to Read More

Using proprietary production techniques, and benefiting from an ultra-stable production facility, Optical Surfaces Ltd has established itself as a leading supplier of fast focusing on-axis parabolic mirrors for high power laser experiments. Inherently on-axis parabolic mirrors allow a higher f-number (<0.7) to be achieved than off-axis designs the Read More

Specialised Imaging reports how US researchers** used its Kirana ultra-high speed video camera to investigate the effects of liquid and solid impacts on hypersonic aerospace bodies. When an object moves through the atmosphere at hypervelocity, it can get damaged by dust particles or water droplets suspended in that atmosphere. Simply firing dust Read More

SI Sensors – a pioneering developer of advanced imaging technologies, is proud to announce a groundbreaking development in the field of high-speed imaging: the integration of Charge-Coupled Device (CCD) technology within Complementary Metal-Oxide-Semiconductor (CMOS) image sensors. This innovative approach, known as CCD-in-CMOS, significantly e Read More

Spectrograph optics for astronomical telescopes Optical Surfaces Ltd is a leading producer of ultra-high precision optical components and systems for telescope spectrographs. The main function of a telescope spectrograph is to separate light into its component colours (or wavelengths) to reveal information about the chemical content, temperature Read More

The SI-VT2 Velocity Trap from Specialised Imaging is a precision instrument that enables ultra-high-speed cameras studying ballistic events to automatically adjust image triggering in real time. If the velocity of a projectile in a ballistic impact experiment varies - then the time it hits the target will change. The velocity trap enables ultra-h Read More

Resolve Optics has delivered the first batch of a new version of its popular Model 357 non browning 10x zoom lens to a leading manufacturer of radiation resistant instruments. Optimised for a ¼-inch format camera sensor – the new lens can withstand exposure to radiation to over a million Gy, enabling operation in nuclear plant hot zones to ensure Read More

Optical Surfaces Ltd. has received a follow-on order from the Scottish Centre for the Application of Plasma-based Accelerators (SCAPA) at the University of Strathclyde (UK), for two ultra-high performance off-axis parabolic mirrors. These new mirrors will be deployed in a state-of-the-art laser-driven proton and ion beam accelerator on campus. The Read More

Drawing upon a team of specialists with a broad range of experience in image sensor design and a growing intellectual property (IP) portfolio – SI Sensors provides a cost-effective full service for design, development, and manufacture of custom CMOS sensors. Some new product developments may employ a standard commercial off-the-shelf (COTS) sensor Read More
