    MicroPhotoMeter

    Overview Knowledge Standards Terms
    A microspectrophotometer combines a microscope and a spectrophotometer to measure the optical properties of tiny areas. It is used to analyze surface color, reflectivity, and transmittance of materials, as well as to detect coating uniformity, color differences, and component distribution in industries such as coatings, plastics, and printing.
    Selection
    When selecting a micro-photometer, consider the measurement area size to match the microscope magnification, confirm that the spectral range covers the detection requirements, evaluate the sample stage's load capacity and positioning accuracy, check whether the software analysis functions support industry-standard indicators, and verify the ease of instrument calibration and maintenance.
