SPECTROPHOTOMETER |
摘要 |
<p>Disclosed herein is a spectrophotometer which includes a source of radiation; an optical system for forming a beam of radiation from the source and directing it along a sample path and along a reference path, which paths come together at a location to form a combined path that impinges on a detector; a chopper mounted at said location for successively directing one or the other of the beams along the combined path or providing a blank chopper area for blocking radiation from the combined path; a monochromator having a grating and slits disposed in the combined path, the angular position of the grating being adjustable for passing selected successive wavelengths of radiant energy through the optical system; and controls are provided for controlling the movement of the grating and/or slits so that movement only occurs when the blank chopper area is blocking the combined path.</p> |
