Key Features

From FERGIE to IsoPlane 81

Taking advantage of IsoPlane technology, the spectrograph previously known as the FERGIE has received significant upgrades to create what is now the IsoPlane 81. This ensures the highest resolution of spectra with its aberration-free design, superior signal-to-noise, as well as in-built kinetics for fast spectral imaging.

Alongside utilizing this technology, the IsoPlane 81 has also been enhanced (from the FERGIE) for optimal performance. With electronic improvements to reduce readout noise, better access to gratings for ease of alignment, and external upgrades the IsoPlane 81 is of outstanding quality.

Aberration-Free Optical Design

IsoPlane 81 spectral profiles are completely coma and aberration free, eliminating broadened asymmetric peak profiles over any wavelength at any grating angle.

This significantly improves signal to noise ratio and peak resolution.

Pre-Calibrated Accessories

IsoPlane 81’s pre-aligned optical modular spectroscopy cubes, fiber optics and laser sources enable rapid experiment design already pre-calibrated.

This allows for ultimate experimental flexibility, with accurate, repeatable, and easy spectral data acquisition.

Integrated Thermoelectrically Cooled, Back-Illuminated CCD

The IsoPlane 81 is equipped with a deep-cooled CCD detector, providing extreme high sensitivity with peak 95% QE.

Thermoelectric cooling to -45℃ allows for long integration times ideal for faint signal detection.

In-Built Kinetics Spectroscopy Mode and Frame Transfer CCD

The customizable kinetics spectroscopy modes of the IsoPlane 81 allow for microsecond time resolution.

Full frame image capture at 34 fps is achieved due to the high-speed frame transfer CCD detector, with spectral rates over 1 kHz (10 row binning)
