- Model 272 - High Throughput f/2 Monochromator



The Model 272 monochromator contains a large, 100-mm diameter diffraction grating. This guarantees a large solid angle of light collection. The gratings corrected design reduces optical aberrations. This improves the spectral resolution of this high throughput optical system. The Model 272 is a versatile research grade monochromator. It delivers high throughput and moderate spectral resolution. Usable in any attitude, standard features of much larger McPherson monochromators have found home in this high efficiency f/2 monochromator.
