OFR D/8°
Reflectance Measuring Head

Product Information

Applications
The OFR D/8° measuring head is designed for non-contact reflection measurement ofglossy and scattering samples. The OFR D/8° is part of the accessory program of thediode array systems MCS 500 and CORONA and is optimized for use with these systems.
It can be used to measure with specular included or excluded.

Function
The sample is diffusely illuminated through an Ulbricht integrating sphere. The sphere
either contains a halogen lamp or is illuminated by an external xenon flash lampconnected by a fiber. The light reflected by the inside wall of the sphere can betransmitted to a reference spectrometer through an optical fiber.
The light to be measured is imaged to an optical fiber connector. It is sent to the sample
spectrometer through an optical fiber. The Ulbricht integrating sphere is protectedagainst contamination by a BK7 glass plate.

OFR 90Reflectance Measuring HeadProduct Information

Applications
The OFR 90 Measuring Head was specially designed for non-contact reflection measurements of clear and scattering samples (e.g. window glass).
It is suitable for color measurements and for NIR reflection measurements as well.

Function
The sample (2) is diffusely illuminated through an Ulbricht integrating sphere (4). For this,the light of either a halogen or xenon lamp is transmitted to the OFR 90 Color Measuring
Head through a fiber bundle (1). Optionally, a halogen lamp can be used in place of thefiber bundle (1) to directly illuminate the sphere and thus increase the light intensity.
The light reflected by the inside wall of the sphere is guided to the reference
spectrometer through another fiber (5). The light to be measured is imaged onto opticalfiber (7) by a 2:1 imaging optics (6). This fiber is connected to the sample spectrometer.
The optical fibers used are quartz fiber bundles.
The Ulbricht integrating sphere is protected against contamination by a BK7 glass disk(3).
