The
VRMS-1200 Visible Reflectance Measurement Systems are designed
for the measurement of normal/diffuse reflectance of a variety
of materials, from front surface optics to architectural materials
to computer screens. Four system options are available, each
designed in accordance with ISO, ASTM and CIE standards for
the measurement of luminous reflectance/transmittance and
chromaticity.
The systems feature 12 inch diameter
integrating spheres designed for the measurement of reflectance
and transmittance. The integrating sphere of the VRMS-1208
series is equipped with an external sample mount designed
to allow for 8°/diffuse reflectance measurements. The integrating
sphere of the VRMS-1230 series is equipped with an external
sample mount designed to allow for 30°/diffuse reflectance
measurements. A KI-125 Koehler Illuminator provides a collimated
light source to illuminate the sample.
Reflectance
samples are placed in the external sample mount of the integrating
sphere. An optional variable angle center mount sample holder
accommodates solid samples up to 1 inch in diameter. By
rotating the optional center mount about its axis, the sample
can be illuminated at the desired incident angle. The energy
reflected from the sample is fully integrated before reaching
a baffled detector assembly. The reflectance is weighted
and integrated by the CIE Standard Photometric Observer
Function.
Samples
may also be placed in the transmission sample holder of
the integrating sphere. The energy transmitted through the
sample is fully integrated before reaching the baffled detector
assembly. The transmittance of the sample is weighted and
integrated by the CIE Standard Photometric Observer Function.
for the measurement of luminous reflectance
and transmittance
The
VRMS-1208L Visible Reflectance Measurement System is designed
in accordance with ISO 5740 Extension, ASTM E429 and ASTM
E1477 specifications and features a PSD-030 Photopic Sphere
Detector Assembly and an SC-5500 Integrating Sphere System
Control for luminous reflectance and transmittance measurements
of materials. The system's integrating sphere is equipped
with an external sample mount designed to allow for 8°/diffuse
reflectance measurements. A Koehler Illuminator provides
a collimated light source to illuminate the sample.
The
VRMS-1230L Visible Reflectance Measurement System is designed
in accordance with ISO-5740, ASTM E429 and ASTM E1477 specifications
and features a PSD-030 Photopic Sphere Detector Assembly
and an SC-5500 Integrating Sphere System Control for luminous
reflectance and transmittance measurements of materials.
The system's integrating sphere is equipped with an external
sample mount designed to allow for 30°/diffuse reflectance
measurements. A Koehler Illuminator provides a collimated
light source to illuminate the sample.
for the measurement of luminous reflectance
and transmittance, chromaticity and spectral analysis
The
VRMS-1208S Visible Reflectance Measurement System features
a DAS-1100 Diode Array Spectrometer for highly accurate
analysis of spectral reflectance, luminous reflectance,
chromaticity and other color properties. The spectrometer
Offers a measurement range covering the visible region of
the spectrum from 390 nm to 760 nm. A Koehler Illuminator
equipped with a 125 W halogen lamp provides a collimated
light source to illuminate the sample. All reflective viewing
optics relay the sample's reflectance spectrum into the
diode array spectrometer. Windows-based software is provided
with the VRMS1208S Visible Reflectance Measurement System.
The
VRMS-1230S Visible Reflectance Measurement System features
the DAS-1100 Diode Array Spectrometer for highly accurate
analysis of spectral reflectance, luminous reflectance,
chromaticity and other color properties. The spectrometer
offers a measurement range covering the visible region of
the spectrum from 390 nm to 760 nm. The system's integrating
sphere is equipped with an external sample mount designed
to allow for 30°/diffuse reflectance measurements. Windows-based
software is provided with the VRMS-1230S Visible Reflectance
Measurement System.
The
VRMS-12XXS Systems are also available with the DAS-2100
Diode Array Spectrometer. The DAS-2100 offers an extended
measurement range covering the spectral region from 350
nm to 1050 nm.
The
Windows-based software supplied with the VRMS-12XXS Visible
Reflectance Measurement Systems consists of a single screen
which reports the spectral transmittance or reflectance
of the sample. Spectral data may be applied to computer-stored
data for several different illuminants to yield important
color properties of the sample. The spectral data may be
exported for use in a spreadsheet or it may be printed for
review and archiving.
Software
is available for the VRMS-12XXL Visible Reflectance Measurement
Systems to control the SC-5500 Integrating Sphere System
Control, turn the power supply on and off and monitor the
transmittance and reflectance of the source. Contact the
Technical Sales Department for further details about application
software.
