Absolute Total Reflectance Spectra of Very Small Objects using the ISR-2600Plus Integrating Sphere

Often reflectance spectra of very small samples are required. Typical sphere openings and sampling accessories are designed for samples in the 25mm x 25mm range with maximum thicknesses of 1 cm. Consequently, correct positioning of such samples to acquire accurate spectra can be very challenging.
This application note demonstrates an easy-to-fabricate holder that is suitable for many small samples. In addition, it shows the measurement of absolute total reflectance using this sample holder.
