Probe Holder


  • An essential tool for angled reflectance measurements
  • Seventeen angles available: 20 to 90 degrees (5 degrees steps)
  • Allows diffuse and specular reflectance measurements
  • Measurements can be performed using one or two probes
  • Get the best accuracy and flexibility with the new slide system

Meet the multiangle probe holder

The multiangle probe holder is a robust tool made from black anodized aluminum for conducting angled reflectance measurements with our standard reflection probes with 6.35 diameter tips.

With a wide range of angles from 10 to 90 degrees (with 5 degree step), reflectance measurements can be easily made using one (a probe that irradiates and collects light using the same tip) or two probes (one probe is used for irradiation and the other is used for collection).

What makes it different?

The multi-angle probe holder includes a number of important features that improve significantly the quality of your reflectance measurements.

All angles in this tool have a position fixer to ensure that the probe tip, which also includes an adjustable backstop, is always inserted in the same position and distance from the sample, when you change between angles. The stand of the multi-angle probe holder includes the new slide system.

New Slide System for Reflectance


The slide system is a remarkable tool designed to provide a fast and simple way of changing between different samples without the need to touch or move the probe holder (this system is important to ensure a fixed distance between reflectance measurements). 

To increase the flexibility of the slide system, Sarspec has developed a wide range of slides supports that can also be used in connection with the slide system of our integration sphere and multi-angle probe holder.

The slide supports available can be used for powders, fabrics, films, and solutions. Sarspec has also slide supports with built-in references (for diffuse and specular measurements) and for standard microscope slides (25 mm x 75 mm).
