【Overview】
The DTMc300 double monochromator combines two TMc300 (300mm focal length) monochromators operating in unison, in additive or subtractive dispersion mode, providing strong stray-light suppression for high-dynamic-range spectroscopy.
【Key Features】
(1) Double monochromator design with excellent stray-light rejection;
(2) Up to 3 diffraction gratings (68×84mm) per TMc300 turret for wide coverage;
(3) Micro-stepped motor drive, 0.00072°/step (500,000 micro-steps/rev);
(4) 6- or 8-position order-sorting filter wheel;
(5) Computer-controlled SAM for entrance/exit port selection;
(6) Fixed / micrometer / motorised slits, fully automated USB control.
【Typical Applications】
UV/VIS/NIR spectroscopy, laser spectral analysis, precision monochromatic sources, weak-signal detection.
