The Selector

The Selector is an expandable diffuse reflectance sampling system that can change with your applications

Diffuse reflectance is based upon the collection of radiation that has been diffusely scattered from the sample. The Specac Selector uses anptimized off axis optics configuration which selectively collects the diffusely reflected components, whilst minimizing the specular component.

In addition, an abrasive sampler, 12 mm diameter, can be used with Diabrase pads to allow quick and easy sample preparation of intractable solids. The abrasive pad is simply rubbed against the sample of interest and mounted in the Selector accessory. The Selector™ is mounted on its own baseplate. The off-axis design allows room for the use of specialist alternative configurations. The Environmental Chamber option extends the sampling capabilities of the Selector.

Key Features

  • Diffuse or total reflectance capabilities
