ISDI is an innovator in the field of high performance X-ray detectors and CMOS image sensors. Through its subsidiary Spectrum Logic, ISDI offers CMOS X-ray detectors for medical, industrial and scientific applications. ISDI also designs and manufactures CMOS image sensors and other ASICs for the detection of X-rays, visible light, electrons and protons. We offer a range of high performance image sensors as well as custom design services to meet customer’s specific requirements.
ISDI offers a range of real-time wafer-scale CMOS image sensors and sensor arrays with 50 µm, 75 µm, 100 µm and 150 µm pixel pitch. These are designed with a range of sensitivities and options which meet the demands of a wide range of X-ray imaging applications. Sensor sizes range from 6 x 6 cm to 31 x 31 cm. A range of line-scan sensors arrays are also available in 15 cm x 0.7 cm and 23 cm x 0.7 cm formats for dental extraoral and industrial applications.
Spectrum Logic is part of the ISDI group and is a manufacturer and designer of X-ray detectors and other imaging products using wafer scale CMOS image sensors. Spectrum Logic develop custom and standard X-ray detectors using wafer scale CMOS image sensors (from 50 μm to 150 μm pixel pitch). The detectors are used in scientific, medical, veterinary, security and NDT industrial applications.
Spectrum Logic provide fibre optic plate attachment to arrays of wafer-scale image sensors up to 31 × 31 cm. Full compliance and environmental qualification is offered as part of product development.
Designers of imaging systems often have very specific requirements – for example, a specific size, pixel spacing, sensitivity or frame rate – which cannot be provided by the limited selection of CMOS image sensors on the market.
To fill this gap, ISDI provides a complete service for the design and production of custom image sensors. We specialise in small to medium size volumes, where the mainstream semiconductor sensor vendors cannot offer an economically viable solution.
The IS1510 CMOS image sensor has been used to design the Spectrum Logic CL1510 1:1 Western Blot Imager - a novel scanner for faster, more accurate results.
Western blotting (also known as immunoblotting) is an established biochemical procedure that identifies particular proteins in complex samples and has applications from straight-forward research to the analysis and diagnosis of infectious diseases. Western blotting can be utilised to decide molecular weight, amount and post-translational adjustments of proteins and can subsequently be an effective device to screen changes in proteins, including expression and modifications.
Raman spectroscopy, which is now a vital tool in life sciences and materials analysis, it was an insight by a scientist who spent his entire professional life in his home country India. Chandrasekhara Venkata Raman had been investigating how light interacts with materials at the molecular level and hypothesised that light could be scattered by materials in such a way that the properties of the light are changed.
