Circular Dichroism Spectrometer

J-815 Circular Dichroism Spectrometer

The latest achievement in the JASCO commitment to lead the field of Circular Dichroism

JASCO proudly announces the new model J-815 Spectropolarimeter, our latest Circular Dichroism spectrometer. Unparalleled optical performance and optionally available measurement modes are combined in a manner to make the J-815 a true “chiro-optical spectroscopy workbench”. Instrument control and data processing are handled effortlessly by JASCO’s user friendly and innovative cross-platform software, Spectra Manager™II. As an option, Spectra Manager™ CFR provides secure access and compliance features for industries under an FDA 21 CFR 11 mandate.

PEM Crystal

Since 1961, JASCO has designed and built the finest in chiroptical instrumentation. With 45 years of experience, the result is the best performance and reliability in the industry. Instead of using instrument components from other manufacturers, the entire instrument is designed and manufactured by JASCO. The mirrors in the J-815 are produced by a proprietary surfacing/plating/coating technique resulting in the highest reflectivity and optical throughput. The PEM is considered the heart of the CD instrument and the temperature-stabilized natural crystalline quartz prism eliminates instrumental drift. Finally, all electronic systems are optimized for maximum performance and reliability.
