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.
