Circular dichroism (CD) spectroscopy is widely used in the study of optically active substances. CD The CPL-300 Circularly Polarized Luminescence Spectrophotometer supplements the information obtained from other chiroptical techniques such as electronic or vibrational circular dichroism. Circular dichroism (CD) spectroscopy is widely used in the study of optically active substances. CD spectroscopy provides information about the structure of optically active substances in the electronic ground state, however, CPL spectroscopy provides information about excited states. The two techniques are therefore complimentary. The CPL-300 uses the original 180° fluorescence collection approach proposed by Steinberg. The standard ozone-free 150W Xe lamp can be user-replaced with an Hg/Xe source. The instrument’s unique double-prism excitation and emission monochromators offer very low stray-light and no spurious linear polarization effects caused by instruments that use diffraction gratings. These are both extremely important as CPL signals tend to be very weak....

The FVS-6000 optical system uses a 28° interferometer with gold coated corner cube mirrors for high throughput and to minimize polarization effects with reflective optics to eliminate artifacts caused by birefringence, resulting in very high-quality VCD data. The FVS-6000 uses a unique highly sensitive narrow-band MCT detector specially developed for VCD measurement across the spectral range 3,200 to 850 cm-1. Optional detectors and filters can be added to extend the range to 4,000 to 750 cm-1, typically for measurement of -OH and -NH bands. Detectors are easily exchanged without the need for manual alignment, and optical filters can be selected automatically....

By controlling the high voltage applied to the PMT, the The V-750 UV-Visible Spectrophotometer optical design uses precision double-beam optics with variable spectral bandwidth. A high sensitivity PMT detector provides accurate and reproducible measurements for low to high concentration samples. By controlling the high voltage applied to the PMT, the dynode feedback offers a wider dynamic range than is generally found on uv-visible spectrophotometers. For high resolution measurements, such as gas and vapor phase spectroscopy, the spectral bandwidth can be set as narrow as 0.1 nm. Special low stray light slit settings which optimize the light image on the monochromator provide increased linearity to up to 5 absorbance units....
