This Eisco Premium Diffraction Grating (PDG19C) is designed for optical experiments and spectral analysis requiring precise light separation. Its key benefit is a high density of 300 lines per millimetre for detailed spectral resolution. A potential caveat for international buyers is that electrical items ship with a 3-pin UK plug by default. This transmission grating, housed in a 50 x 50mm frame, offers clear spectral dispersion for educational and research applications.

The primary use is to separate light into its constituent wavelengths, allowing for spectral analysis and demonstration of diffraction principles.
This diffraction grating features 300 lines per millimetre.
The diffraction grating is mounted in a 50 x 50mm frame.
This grating is primarily designed for visible light. Its performance in UV or IR ranges would depend on the specific material properties, which are not detailed here.
Handle by the edges to avoid touching the optical surface. Store in a protective case when not in use to prevent dust and damage.
The difference lies in the line density: PDG19A has 80 L/MM, PDG19C has 300 L/MM, and PDG19E has 1200 L/MM. Higher line density generally provides higher spectral resolution.
The product description does not specify included mounting hardware. It is typically designed to be integrated into existing optical setups.
Ensure the grating is correctly oriented and the light source is aligned properly. Check that the light source is sufficiently intense and that the screen or detector is at an appropriate distance. Verify the grating is clean.
Confirm the grating is mounted securely and not warped. Ensure the light source is a point source or has a narrow slit for best resolution. Check for vibrations in the setup.
Gently clean the surface with a lint-free optical cloth or lens tissue. Avoid excessive pressure. For stubborn marks, a specialized optical cleaning solution may be used sparingly.
Setup: This diffraction grating is designed to be mounted within an optical bench or a custom apparatus. Ensure it is positioned perpendicular to the incoming light beam for maximum efficiency. For best results, use a stable light source and a suitable screen or detector to observe the diffracted spectra.
Compatibility: The 50 x 50mm frame is a standard size compatible with many optical mounting systems. It is primarily used for visible light spectrum analysis, but its performance with other parts of the spectrum depends on the material's transmission properties.
Care: To maintain performance, handle the grating by its edges to avoid fingerprints or damage to the delicate diffraction surface. Clean the surface gently with a lint-free cloth or optical lens tissue if necessary. Avoid abrasive cleaners or solvents. Store in a protective case when not in use.
