Mid-IR External Integrating Sphere

Mid-IR External Integrating Sphere

An integrating sphere is very often an accessory of choice when studying reflectance properties of solids, analyzing light scattering of highly absorbing samples and collecting spectra difficult to obtain with standard sampling techniques. The External Integrating Sphere Accessory, which utilizes the external beam of the spectrometer, is ideal for large samples due to the additional sampling space realized by positioning sample underneath the sphere for precise reflectivity measurements. 

  • Accommodates large-sized sample
  • 4 inch sphere – gold-coated, Lambertian scatterer for high performance measurements
  • 8 degree hemispherical diffuse reflectance measurement with specular exclusion port
  • Utilizes external spectrometer beam to allow for the analysis of oversized samples positioned under the sphere
