The ARCspectro VIS-NIR DR combines two spectrometers: a
standard multichannel grating spectrometer that covers the visible
spectral range (360nm-950nm) and the Arcoptix NIR scanning
Fourier-transform spectrometer with an extended range InGaAs detector
which is sensitive in the NIR range from 900 to 2500 nm. Both
connected to a 5 cm integrating sphere. The sample is
illuminated with perfectly diffuse light thanks to the integrating
sphere including a high power
The ARCspectro VIS-NIR DR allows you to measure the
reflectivity of materials and paints over the complete solar spectral
range - from 360 to 2500nm. This is important for the painting, building
or solar energy industries, because it provides crucial information
about the solar energy absorbed and transformed into heat by those
materials or paints.
Those charateristics make it an ideal tool for measuring the Total Solar Reflectance (TSR) according
to the ASTM ® norms G173 and E903. The software included with the
VIS-NIR DR automatically calculates the TSR value. The ArcSpectro
VIS-NIR DR complete measurement system is proposed for only 24'900 EUR.
This offers an interesting alternative to other
commercially available spectrophotometers which may be
more versatile but are also slower, more complex, and much more costly.
