Spectrum Logic launches 2824HS: A super-fast detector for NDT and X-ray Microscopy

Spectrum Logic, an innovator in X-ray imaging solutions, today launched the latest product from its range of large area flat panel detectors. 2824HS, a super-fast X-ray detector with imaging area of 280 x 240 mm2, supporting 90 fps for an active image size of 2802 x 2400 pixels. Even higher frame rates are possible in region of interest (ROI) mode. Targeting advanced industrial CT and X-ray microscopy applications, the 2824HS is a CMOS (complementary metal oxide semiconductor) based X-ray flat panel detector (FPD) that provides high resolution images and covers a wide energy range.

The combination of the pixel pitch of 100 µm, 90 fps readout provides super-fast imaging required by demanding applications such as pre-clinical CT, X-ray diffraction and X-ray microscopy. The detector the largest member of our 100 µm HS family. The 2824HS detector has been designed and developed particularly for high speed, high energy X-ray applications with lead shielding to protect electronics and CMOS sensor from radiation damage and hence offering longer lifetime in the field.

The 2824HS is comprised of an array of four wafer-scale CMOS sensors precisely stitched together with a maximum gap of 100 um between the centre of neighbouring active pixels (one row or column). With a choice of high resolution CsI, high efficiency CsI or Gadox scintillator, the 2824HS is an ideal candidate for dynamic imaging with superior image quality over a large range of scientific and industrial applications. Having a saturation dose of 4 µGy and MTF of 10% @ 5 lp/mm with high resolution CsI scintillator, it is an ideal choice for low dose per frame and high frame rate imaging applications, including real time NDT inspection.

The 2824HS is offered with a choice of three interfaces including Camera Link, USB 3.1 and 10 Gigabit Ethernet. The USB is a simple plug-and-play interface which can be used with our Graphical User Interface (GUI) Software to get up and running in minutes without requiring a frame grabber. Our in-house software development supports offers a Windows-based software development kit (SDK) for easy and smooth integration to into the customer’s software. The SDK offers image capture and corrections.

Ed Bullard, Chairman of Spectrum Logic commented that, “the 2824HS is one of the fastest wafer-scale CMOS flat panel X-ray detectors in the world. Given its large field of view and highly sensitive active pixel sensor, it is a great fit for applications like X-ray Microscopy where high geometric magnifications are combined with low dose. Our vision at Spectrum Logic is to utilize our world leading CMOS sensor technology to develop high end, high quality X-ray detectors for professional applications in NDT and scientific X-ray imaging”.

Spectrum Logic launches 2824HR CMOS flat panel Detector

Spectrum Logic, an innovator in X-ray imaging solutions, today launched the 2824HR CMOS X-ray detector for advanced industrial and scientific X-ray imaging applications. The 2824HR is a CMOS (complementary metal oxide semiconductor) technology-based X-ray flat panel detector (FPD) that provides high resolution images and covers a wide energy range. It has an active area of 28 cm X 24 cm.

With pixel pitch of 50µm, 26M pixels offer ultra-high-resolution images in applications such as pre-clinical radiography, pathology, X-ray diffraction and industrial CT. The detector belongs to our 50um HR family which offers 1412HR, 1206HR and 0606HR solutions. The 2824HR detector has been designed and developed particularly for high energy X-ray applications with lead shielding to protect electronics and CMOS sensor from radiation damage and hence offering longer lifetime in the field.

The 2824HR is an array of 4 CMOS sensors precisely stitched together with maximum 100um gap between active pixels.  A fibre optic plate is bonded on top of the sensors to protect the image sensors from X-ray radiation enhancing image quality and product lifetime. With a choice of high resolution CsI or Gadox scintillator, the 2824HR is an ideal candidate for static and dynamic imaging with superior image quality over a large range of scientific and industrial applications.

“We are very proud to expand our product range to high-resolution industrial applications with the new 2824HR. It is a milestone for high resolution x-ray imaging in industrial and scientific markets including synchrotron applications. Our 50µm HR family is already offering the fastest flat panel detectors with this resolution. The 2824HR enables our users to capture high resolution images with the greatest accuracy and speed. Our customised GigE interface offers up to 10Gbps to support 5608 x 4802 pixels and dynamic imaging for large parts inspections.” says Asmar Khan, Product and Business Development Manager at Spectrum Logic.

2824HR a wafer-scale CMOS image sensor with low noise active pixel sensor technology (APS) and state-of-the-art column parallel 14-bit ADCs. The sensor offers two gain modes to support different applications.

The 2824HR is offered with a choice of three interfaces including Camera Link, USB 3.1 and 10 Gigabit Ethernet. Our in-house software development team offers a Windows-based software development kit (SDK) for easy and smooth integration to into the customer’s software. The SDK offers image capture and corrections.

The 2824HR offers 2 types of active cooling. Active air-cooling system is available immediately and water cooling will be available in Q2 2021.

Spectrum Logic wins grant to develop a novel Western Blot Covid19 anti body test

Spectrum Logic wins grant to develop a novel Western Blot Covid19 antibody test

London – 9th June 2020 – Spectrum Logic today announced that it has been awarded an Innovate UK grant to develop a novel Western Blot scanner to be used in the first instance for Covid19 antibody testing. The project is entitled ‘Low Cost, High Throughput Western Blot Antibody Detection Device for Those Already Infected with COVID-19’.

There is an unmet need for COVID-19 antibody testing for those already infected with SARS-CoV-2. This can be accomplished using serological Western Blot assays in a lab setting by detecting the presence of antibodies to SARS-CoV-2 proteins in blood samples. The antibodies bind to antigen proteins and are visualized using chemiluminescence. This test can show whether your adaptive immune system has fought-off SARS-CoV-2 months or possibly years earlier. It is thought likely, but has yet to be confirmed, that the presence of antibodies will confer immunity on some or all people. Western Blot assays have been used for many years to test for Hepatitis B and other viral diseases. Unlike home test kits, they offer excellent sensitivity and specificity approaching 100%. High specificity is especially important for SARS-CoV-2 antibody testing because of the low prevalence of antibodies in the population. The test will permit multiplexing with multiple samples run in parallel.

Western Blot as a method offers superior accuracy when compared to lateral flow serology and possibly also enzyme-linked immunosorbent assay (ELISA).

“The Spectrum Logic Western Blot scanner will help scientists understand the pandemic by giving researchers a more accurate measure of how many people have had the COVID-19 virus and the nature of the immune response generated. On a personal level, many people wish to know whether they have already suffered from COVID-19 and possess protective IgG antibodies.  With the help of Innovate UK grant funding Spectrum Logic will help to deliver these answers,” commented Ed Bullard, CEO of Spectrum Logic

Existing Western Blot instruments can be expensive and have poor sensitivity, because they use either scanning line sensors or lens-coupled CCDs. Spectrum Logic’s instrument will enable accurate laboratory antibody testing to be ramped up inexpensively. The project funded by the Innovate UK grant will use unique, large-area CMOS image sensors coupled to fiber optic faceplates for 1:1 imaging without a lens or scanning. This allows the Spectrum Logic Western Blot scanner to capture much more of the light emitted during the assay, making it more optically sensitive. Spectrum Logic will develop a new light-tight and waterproof bench-top instrument.

Spectrum Logic Western Blot scanner will be the first product of its type using 1:1 imaging with a large-area image sensor. It will be applicable to other Western Blot applications including COVID-19 antigen testing, life science research, veterinary medicine and food safety.
