Double Beam UV-Visible/NIR Spectrophotometer


The V-780 UV-Visible/NIR Spectrophotometer has a unique optical design incorporating a single monochromator with both dual gratings and detectors to cover the wavelength range from 190 nm to 1,600 nm with enhanced sensitivity in the NIR region using an InGaAs detector.

V-780 UV-visible/NIR spectrophotometer V-780 Double Beam UV-Visible/NIR Spectrophotometer

The V-780 UV-Visible/NIR Spectrophotometer features a single monochromator with automatically exchanged gratings: 1,200 lines/mm for the UV-Visible region and 600 lines/mm for the NIR region. A PMT detector is used for the UV-Visible region and a high-sensitivity InGaAs detector in the NIR region. Both gratings and detectors are automatically exchanged within a user-selectable range of 800 to 900 nm.

Operating Systems

Spectra Manager™ Suite, the innovative cross-platform spectroscopy software, is compatible with Windows 7 Pro (32- and 64-bit configurations) and Windows 8.1 operating systems.

For simple operation, the handheld iRM includes a color touch-sensitive screen. Data can be downloaded for further PC data processing.

The V-780 Series has a growing list of software applications for both Spectra Manager™ and the iRM. If you require an application that you don’t see listed, please let us know as we may already have it or we can prepare an application designed specifically for your requirements.

Both Spectra Manager Suite and the iRM provide full control and advanced data processing with optional 21 CFR part 11 compliant versions.

System Features

IQ Accessory and IQ Start

The IQ Accessory function provides automated accessory recognition. The spectral data files include instrument, accessory, and serial number information. IQ Start together with the Start Button can be used to to start a method for routine measurements.

Enhanced Sensitivity in the NIR region

The V-780 UV-visible/NIR spectrophotometer is used for spectroscopy in the wavelength range 190nm to 1600nm with enhanced sensitivity (compared to a PbS detector) in the NIR region using an InGaAs detector. The single monochromator design offers a higher energy throughput compared to a double monochromator instrument, resulting in a higher S/N ratio throughout the entire spectral range, even using narrow spectral bandwidths.

Sampling Accessories

An extensive range of accessories is available for the V-780 UV-Visible-NIR spectrophotometer for virtually any biological, material science, or routine QA/QC measurement. Refer to the instrument brochure for accessories specific to this instrument.

Options include a wide variety of liquid cell holders, micro and ultra-micro cell holders, flow cell units, and accessories for solid samples. More advanced accessories include automated cell changers, sippers, integrating spheres, automated and manual absolute reflectance accessories, and programmable temperature control systems.

Instrument Validation and Regulatory Compliance

The V-780 includes user-selectable validation to USP, EP, and JP (or manually editable). With optional IQ/OQ.
