About Us
ProTrusTech (PTT) is a recognized leader in Raman spectroscopy based in Taiwan, providing state-of-the-art Raman systems to extensive range of applications. The Raman technology allows fast and non-destructive chemical analysis of solids, powders, liquids and thin film, and has recently become widely used in various research and applied fields. Our mission is to enable our customers to carry out their work in a better and smarter way.

We are an engineering and scientific technology ream that has been drawing on experiences with our customers from academic institutes to industrials labs. In 2008, we established ProTrusTech to continue and improve our achievements, providing Raman systems with microscopy, SERS, TERS, photoreflectance, photoluminescence and electroluminescence.

ProTrusTech substantially believes that success comes from both customer satisfaction and our innovation. Building on our expertise in customization and patented technology, we developed a range of high-quality and reliable products: MRI, MRID, GMD and RAMaker.

RAMaker Spectrometer
All PTT Raman Series can provide auto-switch wavelength of laser.                          
RAMaker provides the function of both Raman and PL with selected
sources 266, 325,355, 442, 458, 473, 488, 532, 633, 785, and 830nm.
LED sources can be applied for only PL measurement. It also provides 
upgrading packages, including InGaAs detector for NIR Raman (1064nm)
& PL, Photocounting PMT for lifetime measurement, fluorescent Image
and combined AFM or NSOM for TERS.
  RAMaker Chamber can adjust three different wavelength laser and
can also be applied way to add more laser source, The laser energy
produced by the software or ND filer. The optical design is suitable
for UV ~ Vis or Vis ~ NIR or UV ~ NIR compliance with various fields
using .RAMaker Chamber included AF Quick, built-in Goggle optic,
Scan / View bar and comply with safety regulations class 1.

RAMaker Chamber also made M475582 patent modulation Raman
design, it input third way source via coaxial into RAMaker Chamber.
Included at least ten different wavelengths of LED light sources for
measuring fluorescent samples, plus source for doing upconversion
and two photon fluorescence. With M475582 patent design, at the
time the signals is measured will not be distorted mapping.
  All lasers go through Auto-Free switched design without wavelength
calibration. The laser energy controlled by the software or N.D. filer
which has six holds wheel can easy reduce laser energy to avoid sample
burning or quenched.

RAMaker included 9M pixels image CCD monitoring and 3W LED white
light will provide a high density visible image and auto scale calculated
with auto exposure to capture real time image.
      
The Raman shift of RAMaker start 90cm-1 (532nm) depends on excitation
laser source and it is powerful tool for researching inorganic materials.
You can also order Anti-Stokes Raman in advise. And Si standard measured
by 10 times should be 520±0.7 cm-1. Intensity of Si wafer is higher than 6,000
counts per second based on 532nm laser excitation.

RAMSpec Software
RAMSpec Software function includes timely display of scanning spectra, automatic
calculation of A/B ratio, intensity distribution, and Raman shift distribution. Mapping
function includes Raman signal 2D and 3D displays. RAMSpec Software also
provided optional functions included  quantity and user database search.   Optional Dynamic analysis and trend measurement function, providing 2D / 3D display
, can be for A / B ratio, peak wavelength, absorption, penetration and user-defined
parameters, the peak position, width and half-wave surface integral real-time display.
Time resolution spectral and colorimetric analysis. With elements of the search function,
you can analyze atom and ion type.
