An Unparalleled Instrument For Your Demanding Applications
When you can't dilute the sample or reduce the path length, think of the UV-2501PC. The double blazed grating, double monochromator (DDM) in this instrument is just waiting for those samples. Shimadzu has achieved the world's lowest level of stray light and highest energy throughput with this unique design. By creating two blaze wavelengths (200 nm and 600 nm), Shimadzu has overcome the energy loss and sensitivity restrictions usually associated with double monochromator instruments. The face of the grating is actually divided into two unique areas for short and long wavelength measurements. The sodium iodide spectra for the double monochromator UV-2501PC and a single monochromator instrument shown below put this information into practical terms.

For those research applications that use predominantly the UV and visible regions of the spectrum. The low stray light/wide dynamic range/small beam size combination double monochromator design make this instrument ideal for measurements of highly absorbing species and a range of solutions with a wide linear absorbance range.
