 Clients who bought our ASP-MK350:

Our spectrophotometer has a cosine corrector and is calibrated to measure illuminance and spectral response of light sources. It can be used as a quick, handheld device to verify center, dominant, and centroid wavelengths, intensity, and color of LED and other light sources. Compact spectrometer with performance.

 

Additional Features:

  • Color or monochrome available
  • Color Temperature
  • LED light measurement
  • Spectral Response
  • Color coordinates C.I.E.
  • Integrated Diffuser corrector
  • 3.5" touch screen interface
  • Data transfer to SD card in image format  .bmp and .xls
  • Battery autonomy 4-5 hours average
  • CE approved
  • Tested performance by Calibration National Lab
  • Perfect replacement for Minolta CL-500A

 

Applications:

This spectroradiometer is useful for any type of light emission engines in the visible range such as laser, diode laser, LED, OLED,projector light source, tungsten, Halogen, solar studies, photo-stability testing, and photobiology and fluorescence, phosphorescence applications.
