Description | 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 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....

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....

The J-1700 was specifically designed for more demanding near-infrared CD applications. In addition to the enhanced far-UV capabilities, researchers probing the chiral activity of molecules in the NIR spectral region now have the ability to obtain data at wavelengths up to 2,500 nm. The InGaAs detector has a wavelength range from 900 to 2,500 nm, while the PMT ranges from 163 to 960 nm. The automatic detector interchange allows researchers to obtain both far-UV and NIR measurements without having to manually switch detectors. The addition of a grating monochromator to the double-prism monochromator setup provides low stray light and high light intensity, generating CD signals with high S/N performance throughout a large spectral range....
