Diffraction Gratings Manufacturer,Supplier and Exporter in India

Product Code : SCL-OS-12877

Educational Instrument Diffraction Gratings are supplied as high-fidelity optics components for spectral analysis, diffraction pattern observation, and wavelength determination. The listed grating density options are 100, 300, and 600 lines/mm, allowing teachers to compare how grating spacing changes diffraction angle and spectral separation.

Each grating is supplied in a standard 50 mm × 50 mm slide format for use with spectrometers, optical benches, and universal 50 mm optical rail holders. The manufacturer lists an optical-grade polymer emulsion on a glass or acrylic carrier, supporting clear observation of first-order and second-order diffraction maxima in laboratory teaching setups.

Applications / Uses

Determining the wavelength of monochromatic light using the grating equation.

Observing first-order and second-order diffraction maxima.

Demonstrating visible spectrum dispersion with white light or spectral lamps.

Comparing diffraction angle using different grating densities.

Using with optical sectional apparatus for senior physics practicals.

Pairing with laser equipment for controlled diffraction demonstrations.

How to Use the Diffraction Gratings

Place the spectrometer, optical bench, or rail setup on a stable laboratory table.

Mount the selected diffraction grating in a suitable 50 mm optical holder.

Align the light source so the beam falls normally on the grating surface.

Place a screen or use the spectrometer telescope to observe the diffracted spectrum.

Measure the diffraction angle for the required spectral order.

Repeat the experiment with 100, 300, or 600 lines/mm gratings to compare results.

Calculate the wavelength using the grating equation and record observations.

Safety note: never look directly into a laser beam. Handle the grating by the frame or edges to avoid damaging the optical surface.

Care & Maintenance

Store the diffraction gratings in a dry, dust-free optics storage case.

Do not touch the ruled or coated optical surface with fingers.

Clean the frame only with a soft dry cloth or approved optics cleaning material.

Keep the grating away from moisture, heat, chemical vapours, and abrasive contact.
