V-670 Series Spectrophotometers

The unique single monochromator design of the V-670 requires fewer mirrors to provide a higher throughput resulting in a better signal-to-noise ratio over the entire spectral range. Many UV-Vis/NIR applications require reflectance or transmittance measurements of special optics, films, and wafers. The optional large sample compartment can directly accommodate large samples non-destructively. Several integrating spheres are available including a remote optical fiber unit which can measure the diffuse reflection of a variety of solid samples, such as pastes, clothing materials and food products.

• Unique single monochromator system
• Photomultiplier tube detector for UV/Vis region
• Peltier cooled PbS detector for NIR operation
• Range 190 to 2700 nm (3200 nm option)
• Variable bandpass to 0.1 nm (UV-Vis)

The V-650/660/670 are double-beam spectrophotometers with a photomultiplier tube detector. The high sensitivity of the PMT detector enables accurate measurements of low concentration samples. By controlling the high voltage applied to the PMT, the dynode feedback system allows a wider dynamic range. It also enables the use of such solid sample handling accessories as integrating spheres to collect diffuse light transmitted or reflected by the sample. The advanced optical design offers high optical throughput and low stray light for extended absorbance linearity with the capability for high resolution measurements as low as 0.1 nm for gas and vapor phase spectroscopy.
