McPherson - Model 205 -Very High Throughput Monochromator / Spectrometer
The three versions of the Model 205 have been developed with researchers to meet diverse needs of spectral analysis. The half meter focal length is popular. It provides reasonable spectral resolution, throughput and package size. Every lab has room for a half meter monochromator! Each application is unique and the versions of the McPherson Model 205 will allow you to tailor the instrument to produce better data from a given experiment. Used in air and with a selection of gratings, the spectral range of the 205 extends from 185 nanometersm to 20 microns or more. Multiple ports are available for mounting accessories or CCD detectors, etc. McPherson SNAP IN gratings allow the alignment-free use of many different gratings. All versions work with our digital scan control for scanning or with corrected optics for imaging, all but the quad turret 205wr can be configured for both.
