The AZ Technology PLS 100 Portable Laser Scatterometer represents a substantial innovation in handheld portable instrumentation for determining surface scattering characteristics. The PLS 100 is a reflectometer that uses specular, diffuse, and tetroreflectance (backscatter) measures to determine total integrated scatter and surface is also determined. Any opaque surface finish from specular to Lambertian is measurable.
The measurement wavelength is determined by the choice of laser. Depending on available laser diode wavelengths, measurements from the ultraviolet to the near infrared are possible. The sample is illuminated at 15 degree angle of incidence relative to the sample surface normal. Reference samples used during auto-calibration are supplied with the instrument. The PLS 100 Portable Laser Scatterometer is powered by a camcorder style rechargeable battery pack.
