Best-in-Class Imaging Spectrometers

IsoPlane imaging spectrometers set new standards of performance and versatility.

The patented, multi-award–winning IsoPlane-320 is the best imaging spectrometer in its class. Fast f/4.6 optics and exceptional image quality ensure maximum throughput and signal-to-noise performance. A unique optical design completely eliminates astigmatism across the focal plane for superior multichannel capabilities. There is simply nothing like the IsoPlane-320.

The IsoPlane-160 is a compact 200 mm imaging spectrometer featuring fast f/3.88 optics, a unique astigmatism-corrected optical design, excellent imaging performance, and spectral resolution that rivals most 1/3 meter Czerny-Turner (CT) spectrometers. The best-in-class IsoPlane-160 offers all of this performance and versatility in a compact design.

IsoPlane features include:

  • High spectral resolution
  • Excellent imaging performance
  • Superior signal-to-noise ratio
  • Patented optical design (IsoPlane-320)
  • Triple-grating turrets with auto-turret and
    grating-identification functions


Princeton Instruments’ tradition of technical innovation continues with the multi-award–winning IsoPlane-320 spectrometer, whose exclusive zero-astigmatism optical design provides sharper images and spectra for dramatically improved resolution and signal-to-noise ratio. Resolution comparable to that of a ½ meter spectrometer, with twice the light-gathering power, makes the IsoPlane-320 the instrument of choice for demanding low-light-level applications.

The IsoPlane-160 offers the spectral resolution of a 1/3 meter spectrometer in a compact package. Its unique f/3.88 optical design virtually eliminates astigmatism while providing excellent spectral resolution, making it ideal both for spectroscopy and microspectroscopy applications.

“Hyperspectral laser-line imaging makes high demands on the imaging capabilities of the spectrograph (SPG). We used Princeton Instruments IsoPlane 160, which features aspherical optics that greatly reduces astigmatism and coma aberrations at all wavelengths across the entire focal plane. This makes the spectrograph particularly suitable for multichannel spectroscopy, in our case the Raman line-imaging, due to the reduced cross-talk. Additionally, sharp focusing yields higher signal-to-noise ratios for single spectral features.” Jurgen Popp - Jena University, Germany

Tip-Enhanced Raman Spectroscopy
TERS - Tip-Enhanced Raman spectroscopy

Laser-Induced Breakdown Spectroscopy
LIBS is considered one of the most convenient and efficient analytical techniques for trace elemental analysis in gases, solids, and liquids. LIBS spectra obtained by the Mars Curiosity Rover have confirmed that our sister planet could have harbored life

Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment.

Astronomical Imaging
Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds.

General Raman
The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes.

Surface-Enhanced Raman Spectroscopy
SERS - Surface-enhanced Raman spectroscopy

Coherent Anti-Stokes Raman Spectroscopy
Coherent Anti-Stokes Raman spectroscopy (CARS) a type of non-linear Raman spectroscopy. Instead of the traditional single laser, two very strong collinear lasers irradiate a sample.

Combustion researchers rely on laser-based optical diagnostic techniques as essential tools in understanding and improving the combustion process.

Singlet Oxygen Imaging
Singlet oxygen, the first excited state of molecular oxygen, is a highly reactive species that plays an important role in a wide range of biological processes, including cell signaling, immune response, macromolecule degradation, and elimination of neoplastic tissue during photodynamic therapy.

Plasma Emission Spectroscopy
The different types of plasma emission spectroscopy can be categorized by how the plasma is generated. Spectra of nuclear fusion plasmas are used to ascertain the chemical species present and other properties.

Resonance Raman Spectroscopy
Instead of fluorescence, some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman.

Stimulated Raman Scattering
Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam.

Accurate characterization of surface-enhanced Raman spectroscopy (SERS) biosensors, fluorescent dye molecules that hold great promise for in vivo bioanalyte detection, can often be quite difficult as the overwhelming isoenergetic fluorescence signal typically makes it challenging to measure resonance Raman cross-sections for the molecules. To overcome this obstacle, researchers at the University of Minnesota in Minneapolis recently utilized etalonbased femtosecond stimulated Raman spectroscopy (FSRS), a technique designed to acquire a stimulated Raman signal without strong fluorescence or interference from signals resulting from other four-wave mixing pathway

Better Imaging with a Schmidt-Czerny-Turner Spectrograph
The IsoPlane spectrograph has a unique optical design that completely eliminates field astigmatism at all wavelengths and at all points across the focal plane, and reduces coma to negligible levels. This means the IsoPlane gives sharp and spatially well resolved images across the entire CCD sensor.

Improved Spectra with a Schmidt-Czerny-Turner Spectrograph
The data in this paper have shown that by decreasing optical aberrations and increasing fluence, the IsoPlane gives spectra with better spectral resolution and SNR compared to Czerny-Turner spectrographs. Higher spectral resolution means peaks that are too close together to be resolved by a CT spectrograph can be clearly seen with the IsoPlane.
