RSA-FO-150 Fiber Optic Single Beam Reflectance Spectroscopy Accessory

The compact RSA-FO-150 is an easy to use reflectance spectroscopy accessory designed for use with a multitude of commercially available fiber based spectrometers. When coupled to a light source and spectrometer, this sphere measures hemispherical reflectance for both specular and diffuse samples. 

Key Features:

• Spectralon® Interior; Premier Diffuse
  Reflectance Material
• 8°/H Single Beam Measurement Geometry
• Compatible with Standard Spectrometers
• Rugged Portable Design

The integrating sphere has two SMA 905 fiber ports. The light input port is located on the top of the sphere. It is positioned at 8° from normal for direct illumination of the sample. The second fiber port is located 90° from the sample port. It is positioned to collect the integrated radiance from the sphere wall using a fiber optic spectrometer. The specular subtraction port is standard with the RSA-FO-150. This port is closed for 8°/Hemispherical reflectance measurements or with the simple turn of a thumb screw the port reveals a light-trap for specular excluded measurements. The sample port is near knife edged to permit collection of wide angle scatter.
