MPROBE 40 :SMALL SPOT THIN FILMS THICKNESS MEASUREMENT 

 

MPROBE 40 Thin film measurement system MSP

MProbe 40  measures   thickness and refractive index of thin films in  small spots and with one mouse click. It is used for thousands of applications worldwide and a complete line of standard models is available support them. The thicknesses from 1nm to 2mm, including multilayer filmstacks, can be measured quickly and reliably.  Different MProbe 40 models are distringuished primarily by  wavelength ranges and resolutions of spectrometers, which in  turn determined the thickness range that can be measured.

Small spot thickness measurements are used in several types of applications:

  • on cylindrical or curved surfaces –  syringes, stents, pins, wires, etc. A small spot creates a flat field to achieve accurate measurement even on a highly curved surface
  • non-uniform, rough coatings or light scattering material like high haze or nanoparticles infused films. Small spot localize the measurement and minimize the effects of light scattering and non-uniformity    
  • patterned wafers,  MEMS and other application requiring high lateral resolution / measurement in small areas.

Long working distance objectives (95 mm parfocal length) are used for comfortable and reliable measurement. Large selection of Visible, NIR and UVVisNIR achromatic objectives is available, depending on application requirements.
