High resolution: Reflective gratings are characterized by high resolution, capable of distinguishing spectral lines with very similar wavelengths. This makes them widely used in fields such as spectral analysis and optical measurement.
High efficiency: Compared to transmission gratings, reflective gratings have higher diffraction efficiency. This is because the slits of reflective gratings are typically deeper, allowing for more efficient reflection of light waves and reducing light energy loss.
Wide spectral band applicability: Reflective gratings are suitable for a wide spectral range, from ultraviolet to infrared. This makes them flexible in various optical applications.
As a precision optical element, the core advantage of a reflective grating lies in its ability to modulate and demodulate optical signals through the principle of reflection, making it irreplaceable in fields such as spectral analysis, laser processing, and precision measurement.
