When samples are oriented and polarize incident light, it is important to correct for the inherent polarizing effect of the spectrometer’s optics by using a depolarizer. Another important application is to make measurements using a specific orientation of incident radiation e.g. for crystalline materials and polymers.
The GPOB features a magnetized, ruled optical bench with a moveable 60 mm InGaAs High Performance collection integrating sphere. Samples up to 400 mm in pathlength can be analyzed using the General Purpose Optical Bench. Wavelength range: 190 to 2500 nm.
