  • Fiber Optic Reflectance Sphere for Specular Measurements
  • Cuvette Holder for Use with Liquid or Powder Samples

Spectrometer Accessories are ideal for a variety of spectroscopy applications. The fiber optic reflectance sphere measures hemispherical or diffuse reflectance, or can be used to determine the UV resistance, color, or radiant heat transfer of a sample. The reflectance probe illuminates via six 200μm fibers, and detects via one 200μm fiber.

Note: An additional fiber patch cord is not required. The 10mm cuvette holder enables measurement of transmission, absorption, or fluorescence, and has three SMA905 connections to input and detect light. The cuvette holder requires two fiber patch cords.

The fiber optic reflectance sphere can connect to spectrometers using an SMA Port. Since reflection readings are determined using a comparison method, additional calibration is not required. The fiber optic reflectance sphere includes a specular included/excluded port that can be adjusted using a simple thumbscrew. The sphere is 1.5” in diameter and is incased in an anodized aluminum housing. The light input port is located on the top of the sphere and is positioned 8° from normal for direct illumination of the sample. The second fiber post is located 90° from the 5/16” sample port, and is positioned to capture the integrated radiance from the sphere wall using a CCD based spectrometer. For measurement applications, a white balance reflectance target is recommended. Maximum illumination efficiency is achieved using a 400μm patch cord, and maximum detection efficiency is achieved using a 600μm patch cord.
