FEATURES

  • 8 or 30 Incidence Angle Sphere Geometry
  • Design Specifications Meet:

- ISO 5740 Extension
- ASTM E1477 Specifications
- ASTM E429 Specifications
- CIE 15.2 Specifications

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 Measurements

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.

Transmittance Measurements

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.

SYSTEM OPTIONS
VRMS-12XXL VISIBLE REFLECTANCE MEASUREMENT SYSTEM

for the measurement of luminous reflectance and transmittance

VRMS-1208L

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.

VRMS-1230L

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.

VRMS-12XXS VISIBLE REFLECTANCE MEASUREMENT SYSTEM
for the measurement of luminous reflectance and transmittance, chromaticity and spectral analysis

VRMS-1208S1

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.

VRMS-1230S1

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.

System Software

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.
