PLS
100, Portable Laser Scatterometer
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.
