UV/Vis/NIR Microspectrophotometer

The MSV-300 series is a microspectroscopy system providing transmittance/reflectance measurements of microscopic sample sites for a wide range of wavelengths from ultraviolet to near infrared. Conventional measurements require samples with dimensions comparable to a mm sized optical beam. The MSV-300 series can measure color, film thickness, and other spectral properties of a microscopic area for either large or small samples. The optional automated X-Y-Z stage provides multi-point measurements and surface analysis mapping capabilities.

System Features

  • Wide spectral measurement range
    Continuous measurements between 250 and 2,000 nm (MSV-370) using a spectrometer with a wide band, Cassegrain objective.

  • Simple operation
    The integrated CCD camera allows verification of the analysis site and sample position while defining the sample aperture on the software system.

  • Double-beam system
    Superior measurement stability using a double-beam spectrophotometer.

  • Automated X-Y-Z stage
    With the optional automated stage, discrete measurement areas can be selected using the mouse while simultaneously viewing the sample area on the CCD monitor.
