Q: What is the difference between parallel exit type and vertical exit type monochromators?

A:The only difference between the parallel exit type and the vertical exit type is the exit direction. Since the monochromator is not a square structure, the parallel exit type monochromator has an additional mirror on the basis of the vertical exit type monochromator. Therefore, there are two output options when in use: long side output and short side output.

Q: What is the difference between motorized monochromators and manual monochromators?

A:Motorized monochromators are driven by an upper computer to adjust the wavelength automatically. They usually have higher wavelength accuracy, resolution, faster scanning speed, and better repeatability. Manual monochromators have lower accuracy and repeatability and are suitable for experiments with lower precision requirements.

Q:What is the difference between double outlet monochromators and single outlet monochromators?

A:Compared with single outlet monochromators, the two exits of double outlet monochromators can be switched. According to the actual experimental needs, short side output or long side output can be selected.

Q:What performance advantages do double grating and triple grating monochromators have compared to single grating monochromators?

A:

• High resolution. Multi-grating monochromators can more effectively disperse and analyze the wavelengths of incident light by using multiple gratings in the optical path. Different wavelengths of light can be diffracted and selected multiple times, thereby enhancing the resolution. Compared to single grating monochromators, multiple gratings play a reinforcing role in the spectral dispersion process, effectively improving the system's resolution. Especially when it is necessary to distinguish light sources with very close wavelengths, the multi-grating configuration can significantly improve the accuracy of wavelength selection.
• Reduced stray light. Single grating monochromators often have stray light due to the limited diffraction angle of the grating and the influence of stray light. The multi-grating design utilizes the multiple diffraction and wavelength selection effects of multiple gratings to effectively reduce stray light. Using a dual-grating or triple-grating design can separate and suppress non-target wavelengths of light, reducing the influence of stray light and thereby improving the spectral purity of the output light. Especially for high-precision spectral measurements, reducing stray light is crucial for improving measurement accuracy.
• Extended wavelength range. Multiple gratings combined can operate over a wider wavelength range without sacrificing resolution. Especially when the diffraction characteristics of the gratings allow them to cover a larger range of wavelengths. Multi-grating systems can perform high-precision spectral selection over a broader wavelength range, suitable for applications requiring wide-range scanning, especially in research and industrial applications, covering the UV, visible light to near-infrared (and even wider) range.
• High sensitivity. The multi-grating design can effectively reduce light loss, especially compared to single-grating systems, by optimizing the beam path and enhancing diffraction efficiency through reasonable optical design. This can improve the system's sensitivity, especially for low-light signal or high-precision spectral measurement applications, where the multi-grating configuration can reduce signal attenuation while maintaining accuracy.
• Strong anti-interference ability. Multiple grating configurations can effectively select and separate different wavelengths, avoiding inaccurate measurements caused by interference from other light sources or signals. Multi-grating monochromators have strong anti-interference capabilities in complex environments and are suitable for precise measurements in high-noise environments.
