The Horiba Triax 320 is a high-resolution monochromator engineered for precision spectroscopic measurement and analysis. Built on a 320 mm focal length design with f/4.1 optics, this instrument delivers 0.06 nm spectral resolution and supports multiple grating configurations for flexible wavelength selection. Fully automated operation with motorized slit control, grating selection, and port routing enables rapid scanning and reproducible measurements. The on-axis triple grating turret maintains constant optical performance during wavelength scanning. Purpose-built for laboratory spectroscopy, materials analysis, and research requiring high spectral fidelity across the visible and near-infrared spectrum.
