Bard Hall SB30
The Alpha300R can be used to investigate existing chemistry, track chemical bonds through a process, investigate crystalinity, image strain fields, and measure photoluminescence. Minimum sample volumes of less than a µl are possible since the analysis is taking place through a microscope. Thin films are very common and in some cases monolayers can be measured.
The Alpha300R incorporates 2 laser excitation sources (532 nm and 785 nm), an advanced confocal microscope, 2 high throughput spectrometers and software capable of powerful multivariate analysis into a system that is built around spectral mapping. See the example below for more information on spectral mapping.
Low temperature operation
With the use of a cryostat, Raman spectra can be acquired across a wide range of temperatures from 4.2 K to 500 K. Cryostat operation is possible with Liquid Helium but also with liquid Nitrogen for more convenient and economical testing above 77 K. The cryostat also features an electrical feedthrough with 10 solder studs for electrical connections to a sample or chip. Please contact the facility manager for more information regarding this capability.
