standard Probe Holder

  • An important tool for reflectance measurements;
  • Built for diffuse and specular measurements;
  • Three angles available: 30, 45, and 90 degrees;
  • Improve the precision and flexibility with the new slide system;

The standard probe holder is a robust and simple to use mechanical tool made with black anodized aluminum for securing the probe tip with a fixed distance when measuring the reflectance spectra and color of flat and slightly curved surfaces. With Sarspec’s standard probe holder, users can set the 6.35 mm diameter probe tip at 30 or 45 degrees for diffuse reflectance and 90 degrees (normal to the sample surface) for specular reflectance measurements. Plastic screws (and the key to tighten them) are included in each angle to secure the probe tip and ensure a fixed distance between the probe tip and sample surface. The precision of the standard probe holder can be significantly improved by combining it with Sarspec’s new slide system.

Enhance the precision of your Standard Probe Holder with the

Slide System

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 during reflectance measurements). To increase the flexibility of the slide system, Sarspec has developed a wide range of slide supports that can also be used in connection with the slide system of our Integrating Sphere and Multi-Angle Probe Holder.

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