Ensemble averaging, enterpolation, data set and constants arithmetic (between spectra, between spectra and constants).

An integrating sphere is built-in to permit accurate measurement of solid samples. The sample space around the integrating sphere is ample enough to allow measurement of very large samples.

With the integrating sphere shift function, the range of applications is expanded. V stage built ti. The sample position can be adjusted vertically and laterally.

Powdered sample holder capacity of 0.16ml, 3 included.
