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

Optical Surfaces Ltd. has pioneered a pitch-polishing technique, that produces consistently low surface microroughness on off-axis parabolic mirrors used as key focusing elements for high power laser experiments. Microroughness is a component of surface texture, it can be determined by looking at deviations from the mean line profile of a mirror s Read More

Manufactured to the highest quality standards from cerium doped glass, Resolve Optics Ltd offer a range of fixed focus radiation resistant lenses that can withstand radiation exposure of up to 100 kGy (100,000,000 rads) and temperatures up to 55°C without discoloration. Offering a focal length of 6mm the Model 214 non browning lens delivers high q Read More

Specialised Imaging has delivered a SIMD32 ultra-high-speed camera to the world leading Plasma Physics research group in the Department of Physics at Imperial College (London)**. The Specialised Imaging SIMD32 is a state-of-the-art double shot multichannel framing camera capable of capturing up to 32 images without creating shading or parallax at Read More

Resolve Optics announce a new 6x Non-Browning Zoom Lens design optimised for a 1-inch sensor format shielded camera. Camera sensor size is one the most important factors in determining overall camera performance and image quality. A key advantage of 1-inch sensors is that they are larger than most sensors found in nuclear cameras, which allows the Read More

Dichroic beamsplitters from Optical Surfaces Ltd are commonly used as light guiding optics in telescope spectrographs and to enable multichannel CCD cameras to simultaneously acquire images in different colours. Beamsplitters operate by dividing an incident beam of light into two parts. One part is transmitted through the beamsplitter, the other Read More

SI Sensors design novel CMOS image sensors for ultra-fast cameras that increase the velocity of the signal electrons allowing them to be swept out of the photodiode and be detected much faster. Developing ultra-high-speed CMOS image sensors is difficult because at very high frame rates, the integration time is extremely short and there is never en Read More
