IsoPlane imaging spectrometers set new standards of performance and versatility.

Best-in-Class Imaging Spectrometers

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
