This Eisco Diffraction Grating (PDG19D) is designed for educational and research environments needing to split light into its constituent wavelengths. Its key benefit is providing clear spectral separation with 600 lines per millimetre for detailed analysis. A potential caveat is that it requires a controlled light source and viewing setup for optimal results.

The primary use is to split light into its constituent wavelengths, enabling spectral analysis, which is useful in education and research for identifying elements or studying light sources.
This refers to the density of the grating rulings. A higher number of lines per millimetre indicates a finer grating, capable of providing greater spectral resolution and separating wavelengths more precisely.
Handle the grating by its edges. If cleaning is necessary, use a dedicated optical cleaning solution and a lint-free optical cloth or wipe. Avoid abrasive materials or harsh solvents.
Yes, it is compatible with various light sources, including lasers, LEDs, and broadband lamps. However, the quality of the observed spectrum will depend on the characteristics of the light source.
The diffraction grating is mounted in a 50 x 50mm frame.
This is a transmission type diffraction grating, meaning light passes through it.
Transmission gratings are generally more efficient at dispersing light across a wide range of wavelengths and are often easier to integrate into optical systems where light needs to pass through the dispersing element.
Ensure the light source is directed at the grating and that the grating is properly aligned. Check if the light source is strong enough and if the viewing screen or detector is positioned correctly.
Verify the alignment of the grating and the light source. Ensure the grating surface is clean and free from smudges or dust. Use a more focused light source if possible.
Re-check the angle of incidence of the light beam relative to the grating. Ensure the grating is oriented correctly with respect to the desired dispersion direction.
Setup: Mount the diffraction grating securely in an optical bench or a stable holder. Ensure the grating surface is perpendicular to the incident light beam for accurate spectral dispersion. Proper alignment is critical for obtaining clear spectral lines.
Compatibility: This transmission diffraction grating is compatible with various light sources, including lasers, LEDs, and broadband lamps. It can be integrated into custom optical setups or used with commercially available spectrometers that accommodate 50 x 50mm gratings.
Care: Handle the grating by its edges to avoid fingerprints or smudges on the optical surface. Clean only with optical cleaning solutions and lint-free wipes if necessary. Store in its protective frame or a clean, dry environment when not in use.
