Solid State Division (Opto-semiconductor Segment)The Solid State Division develops and manufactures opto-semiconductors for demanding applications in medical imaging, high-energy physics, and scientic measurement. Products from this division include silicon photodiodes, photo IC components, position sensitive detectors, infrared detectors, image sensors for low-light-level imaging and X-ray imaging, mini-spectrometers, and light emitting devices. In scal year 2018, sales of these products accounted for 46.1% of net sales.Sales of opto-semiconductorsIn opto-semiconductor devices, sales of image sensors for semiconductor fabrication and inspection equipment in the industrial eld maintained a strong performance. In addition, sales of Photo ICs, photodiodes and LED in the FA (Factory Automation) sector for applications such as controls for industrial-use robots and other equipment increased, as well as higher sales of silicon photodiodes for baggage inspections. Opto-semiconductor devices also performed well in the medical eld, and as a result, net sales of opto-semiconductors increased.In total, net sales for the Opto-semiconductor business were JPY 66,569 million, up by 9.9% from the previous year.Systems Division (Imaging and Measurement Instruments Segment)The Systems Division develops and manufactures a wide variety of cameras for scientic and industrial applications, as well as specialized instruments for use in elds such as pharmaceutical development, semiconductor manufacturing, X-ray nondestructive inspection, spectrophotometry, and optical communications. In scal year 2018, sales of these products accounted for 11.9% of net sales. Sales of image processing and measurement systemsIn image processing and measurement systems, sales of digital slide scanners for remote pathologic diagnosis systems and other pathologic applications grew primarily in Europe thanks to the release of new products. In addition, sales of failure analysis systems for semiconductor devices recovered in the second half and increased. However, sales of X-ray line sensor cameras contracted under the impact of inventory adjustment by customers. As a result, net sales of image processing and measurement systems decreased.As a result, net sales for the Imaging and Measurement Instruments business were JPY 17,145 million, down by 0.4% from the previous year.Silicon photodiode module coupled with scintillator used for baggage inspectionSemiconductor failure analysis system “iPHEMOS-DD”7Annual Report 2018
