WELL2789
: Perkin Elmer Lambda-900 950 w/ PELA-1029 Absolute Specular Reflectance Accessory |
|
|
This is an upgraded PE Lambda-900 UV-VIS-NIR
Spectrophotometer that has equipped with a PELA-1029
Absolute Specular Reflectance Accessory(‘V-W’ optical
geometry). This accessory is the primary instrument used
in the characterization of the reflectance properties of
optical materials worldwide. The ‘VW Geometry’
introduces two reflections at the sample. This is
advantageous for samples with high reflectivity since the
signal change to be measured is twice as large. However,
the need for two reflections makes this unsuitable for
small samples, especially at higher angles of incidence.
It is also unsuitable for samples of low reflectance.
Features/Principle:
• Wavelength Range: 175~3300 nm (200~2500 nm if using a
collection sphere)
• Minimum Sample Size: Fixed angle VW – 20 mm x 20 mm
This used/upgraded Lambda-900/950 comes with a CORE-2
PC, Windows-7(8) O/S, the latest version UV Winlab
Software. 90 Days warranty. More details available upon
request.
