Home > Engineering > Plane Spectrophotometric Measuring Equipment  Using an image spectroscope, the plane spectrophotometric measuring equipment captures spectral images by moving printed matter or a sample that has been placed on a table. It then calculates color based on the captured spectral data for display on a CRT monitor either as an RGB color image or as a spectrum of a selected area within the image. Features - Capable of measuring the plane spectrum of an A4-sized object within 70 seconds. - Features a wide range of processing capabilities. Application Fields - Printing relations    Color tone inspection and color separation for printed matter - Research fields    Spectroscopic analysis of plane samples    Near-infrared analysis (PSA-1000) Specifications Model PSA-700 PSA-1000 Wavelength 400-700 nm 400-1000 nm Spectrum Linear spectrum using an ImSpector image spectroscope Processing Spectrum-RGB conversion system (overall screen) Computation of XYZ, RGB, L*a*b*, lab, and CMYK (cyan, magenta, yellow, and black) point values Display of various items such as color difference relative to the specified reference point, color difference area, and specific wavelength image Dimensions Main body: 500 mm (W) x 800 mm (D) x 1072 mm (H) Adjustable table size: 350 mm (W) x 350 mm (D) Sample size: A4 Measuring time Scanning (measuring) time: 0.2 sec./line 70 seconds for A4 size (320 lines), scanning at 1-mm pitches Resolution CCD camera: 480 x 640 pixels Positional resolution, width direction: 0.6 mm/pixel Positional resolution, moving direction: A width of half maximum of 2.5 mm/pitch Geometric wavelength resolution: Wavelength range/number of pixels 300/640≒0.5 nm 600/840≒1.0 nm For color calculation, 5-nm pitches for each reference table Objects Plane samples such as printed matter, coated items, and resin (A special request must be submitted to the manufacturer if the height of the sample is to exceed 20 mm.)
