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 2015, sales of these products accounted for 43.0% of the company’s total revenue.Sales of opto-semiconductorsIn opto-semiconductors, sales in the medical eld of our core silicon photodiodes rose signicantly, largely for medical devices in North America, thanks to these products’ suitability for customers’ needs, while sales of our at panel sensors also remained steady centered on dental applications. In addition, sales of Photo ICs, which are used for optical communication networks in automobiles, also increased in Europe, resulting in the expansion of sales of opto-semiconductors.As a result, net sales in the Opto-semiconductor business came to JPY 51,944 million, up by 5.7% 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 2015, sales of these products accounted for 13.4% of the company’s total revenue. Sales of image processing and measurement systemsIn image processing and measurement systems, failure analysis systems for semiconductor devices have earned a solid reputation for high-denition and high sensitivity in a wide range of elds, which drove a broad advance in sales in Japan as well as overseas. Sales of digital cameras, which enjoy a reputation for excellent performance that meets customers’ needs, increased as well, particularly for the eld of life sciences and biotechnology. In addition, sales of X-ray line sensor cameras, primarily for food inspection applications, also expanded. Reecting these dynamics, sales of the image processing and measurement systems increased.As a result, net sales for the Imaging and Measurement Instruments business were JPY 16,201 million, up by 15.5% from the previous year.Photo ICs for in-vehicle data networksSemiconductor failure analysis system7Annual Report 2015
