ZDG-30 Grating Monochromator

Product Introduction
The ZDG-30 Grating Monochromator is a precision optical instrument designed for qualitative and quantitative spectral analysis. It is suitable for investigating light source characteristics, solution concentrations, photochemical effects, and the optical properties of transparent materials.
Equipped with a precision sine mechanism and stepper motor control, the ZDG-30 supports automatic wavelength scanning and reliable wavelength selection. It is widely used in physics, chemistry, metallurgy, materials science, construction, environmental protection, pharmaceutical research, industrial testing, and education.

Performance Features
• High-Precision Wavelength Selection: A sine mechanism provides accurate wavelength positioning and good repeatability.
• Automatic Spectral Scanning: A stepper motor and controller enable automated wavelength scanning.
• Digital Wavelength Display: A five-digit digital display provides real-time wavelength readings.
• User-Friendly Controller: Integrated control functions simplify operation and wavelength adjustment.
• Flexible Spectral Coverage: The standard wavelength range is 330–900 nm, with alternative grating configurations available for selected bands from 220 nm to 20 μm.
• Compact Design: Separate monochromator and controller units support convenient laboratory installation.

Working Principle
The ZDG-30 uses a diffraction grating to disperse incident light into its component wavelengths. By rotating the grating through a precision sine mechanism, the instrument selects the required wavelength at the exit slit. A stepper motor controlled by the electronic controller enables automatic wavelength scanning, supporting spectral measurements and optical analysis.
