Manufacturer: Princeton Instruments
Product name: IsoPlane spectrograph
UV-vis, Raman spectrometer
New this year: Imaging spectrograph.
Used for: Lab analysis
Measurement Modes: Transmission, reflectance, absorbance, fluorescence, emission, Raman scattering.
Special Features: A practically perfect optical aberration-free imaging spectrograph. Schmidt-Czerny-Turner spectrograph with zero field astigmatism and greatly reduced coma and spherical aberration.
Software: Available as separate product, may be used in other equipment.
Suggested applications: Raman scattering, atomic emission including libs, multichannel spectroscopy, microspectroscopy, Fourier-domain spectroscopy, fluorescence and fluorescence imaging, carbon nanotubes and quantum dots, biomedical imaging
Primary benefits: the IsoPlane gives improved imaging, higher spectral and spatial resolution, and spectra with improved signal-to-noise ratio compared to its competitors. With improved focusing, more photons hit fewer pixels, increasing the resolution and the signal-to-noise ratio of spectra.
Unique features: A practically aberration free imaging spectrograph that is easy to align and focus, grating turret has three positions, three turrets can be used interchangeably, giving up to 9 possible gratings.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
