It operates within the UV to visible spectral range and supports precise wavelength measurement with moderate imaging capabilities. The instrument is typically integrated on an optical bench platform and interfaces with detectors such as photomultiplier tubes or CCDs, allowing connection to data acquisition and control systems for spectroscopy and analytical applications. Commonly used for research and development in physics, chemistry, and materials science. ## Function Dual-grating monochromator/spectrometer for spectroscopic measurements, employing dispersive optical elements to isolate narrow spectral bandwidths from broadband light sources. Operates with interchangeable diffraction gratings in Czerny-Turner optical configuration, providing wavelength selection across ultraviolet, visible, and near-infrared regions. Features adjustable entrance/exit slits controlling spectral resolution and throughput. Compatible with various detectors including photomultiplier tubes, CCDs, and photodiodes. Primarily used for photoluminescence, Raman spectroscopy, optical transmission/reflection measurements, and chemical analysis requiring precise wavelength discrimination. ## Platform Designed as a long focal length (500 mm) monochromator spectrometer with f/4 aperture, optimized for high-resolution spectral analysis with approximately 0.02 nm resolution and 1.6 nm/mm dispersion. It interfaces with standard optical setups, commonly integrating with single-channel detectors such as photomultiplier tubes (PMTs) or CCD detectors via optical fiber or direct coupling. Typically used in research laboratories for applications requiring precise wavelength selection and spectral measurement in the UV-visible range, often as part of custom or legacy spectroscopy systems with manual or computer-controlled wavelength scanning. ## Application Single-channel scanning monochromator designed for ultraviolet, visible, and near-infrared spectroscopy measurements. Performs wavelength selection and dispersion of broadband light sources for analytical chemistry applications including absorption spectroscopy, emission analysis, fluorescence measurements, and material characterization. Commonly integrated with photomultiplier tubes or photodiode detectors for quantitative analysis of chemical concentrations, optical properties determination, and research applications requiring precise wavelength isolation. Used in laboratory environments for routine analytical work, quality control testing, and academic research where moderate resolution spectral analysis is required across the 200-900 nanometer range. ## Accessories Interchangeable gratings, adjustable slits, light sources (Tungsten-Halogen, Xenon arc), various detectors (PMT, CCD, InGaAs array) with controllers, sample holders, fiber optic interfaces (SMA 905).
