Diffraction Grating Demonstration Set
Model Number: MTO-32
The Diffraction Grating Demonstration Set is a compact optical apparatus for investigating diffraction and observing how grating line density influences the resulting light pattern. Micro Technologies supplies the unit with three diffraction gratings having approximately 100, 300, and 600 lines per millimetre. Each grating is mounted in a card frame measuring approximately 90 × 40 mm with a clear aperture of about 16 × 9 mm, providing convenient handling and positioning during experiments. Protective cover glasses help safeguard the grating surfaces from routine handling and environmental exposure. By comparing gratings with different line densities, users can investigate changes in diffraction angle, spectral separation, and wavelength-dependent behaviour in physics and optics laboratory experiments.
Product Specification
The Diffraction Grating Demonstration Set provides a straightforward way to investigate one of the fundamental wave properties of light—diffraction. The set contains three gratings with different line densities, allowing direct comparison of how the number of lines per unit length affects the observed diffraction pattern.
Each grating consists of a large number of closely spaced parallel lines. When suitable light passes through the grating, interference between the emerging waves produces characteristic diffraction patterns. Changing the grating spacing changes the angular position and separation of the resulting orders, making comparative observation particularly useful for understanding the relationship between wavelength, grating spacing, and diffraction angle.
Micro Technologies supplies the Diffraction Grating Demonstration Set with nominal grating densities of approximately 100 lines/mm, 300 lines/mm, and 600 lines/mm. This range provides clearly differentiated grating spacings for comparative optical investigations.
Each diffraction grating is mounted in a card frame measuring approximately 90 × 40 mm. The working aperture is approximately 16 × 9 mm, providing a defined optical area while the surrounding frame makes the delicate grating easier to handle and position.
Protective cover glasses are incorporated to reduce direct contact with the grating surfaces. This improves durability during repeated laboratory use and helps protect the fine optical structure from fingerprints, dust, and accidental handling damage.
The set can be used with a suitable monochromatic or spectral light source to observe diffraction orders and investigate wavelength-related effects. With three grating densities in one compact set, it provides a convenient and economical solution for wave-optics investigations and laboratory procurement.

FAQs
What is the Diffraction Grating Demonstration Set used for?
The set is used to investigate diffraction and interference of light. Different grating densities allow users to compare how line spacing affects the position and separation of diffraction patterns.
How many diffraction gratings are included?
Three gratings are supplied in the standard set. Their nominal line densities are approximately 100, 300, and 600 lines per millimetre.
Why are different line densities provided?
Changing the number of lines per millimetre changes the grating spacing. This allows comparative investigation of diffraction angle and spectral separation under similar experimental conditions.
What is the size of each grating mount?
Each grating is mounted in a card frame measuring approximately 90 × 40 mm, with a clear optical aperture of approximately 16 × 9 mm.
Are the diffraction gratings protected?
Yes. Protective cover glasses are provided to reduce direct contact with the delicate grating surfaces and improve durability during repeated handling.
Can the set be used for wavelength experiments?
Yes. With a suitable light source and measuring arrangement, diffraction gratings can be used to investigate the relationship between wavelength, grating spacing, and diffraction angle.
Which grating produces greater angular separation?
For the same wavelength and diffraction order, a grating with a higher line density generally produces greater angular separation because the spacing between adjacent grating lines is smaller.
Does the Diffraction Grating Set require calibration?
The gratings are specified according to their nominal line density. For quantitative wavelength measurements, the experimental geometry and angular measuring system should also be correctly aligned.
How should diffraction gratings be maintained?
Avoid touching the optical surfaces directly. Keep the gratings protected from dust, scratches, moisture, and impact, and store them securely when not in use.
Can individual grating densities be ordered separately?
Individual grating configurations may be supplied depending on quantity and procurement requirements. Buyers can specify the required lines-per-millimetre value when requesting a quotation.
Can Diffraction Grating Sets be ordered in bulk?
Yes. Bulk quantities can be supplied for physics laboratories, optics laboratories, universities, colleges, research facilities, distributors, and institutional laboratory projects.
How are the gratings packed for shipping?
The card-mounted gratings are protected against scratching, bending, and impact during transportation. Additional bulk or export-grade packaging can be arranged where required.
