Diaphragm with 1 slit
Product Code : SCL-OS-12838
The Diaphragm with 2 Slits by Educational Instrument is a precision teaching accessory used in optical bench and classroom optics setups. The two-slit aperture allows a controlled beam arrangement so students can observe how light behaves when it passes through narrow openings.
This apparatus is suitable for supervised experiments with a laser source, ray box, optical bench, screen, lens, or diffraction setup. It supports practical learning in wave optics by helping teachers demonstrate two-beam formation, interference patterns, diffraction effects, and light-path control in a clear laboratory format.
Key Features
Two-slit diaphragm for controlled light-beam passage.
Useful for interference, diffraction, and wave-optics demonstrations.
Compatible with optical bench, laser source, ray box, and screen setups.
Suitable for school, college, university, and STEM laboratory use.
Helps students observe the relationship between slit aperture and light pattern.
Compact optics accessory for repeatable classroom demonstrations.
Supports safe experiments when used with supervised light sources.

Applications / Uses
Demonstrating double-slit interference in physics laboratories.
Observing diffraction patterns from narrow slit openings.
Teaching wave nature of light in senior school and college optics classes.
Using with a laser source or ray box for controlled beam formation.
Supporting optical bench experiments with screens and alignment accessories.
How to Use the Diaphragm with 2 Slits
Place the optical bench, screen, and light source on a stable laboratory table.
Mount the Diaphragm with 2 Slits in the light path using a suitable holder.
Align the light source so the beam passes evenly through both slits.
Place a screen at a suitable distance to observe the light pattern.
Adjust the distance between the slit diaphragm and screen as required.
Observe the bright and dark bands, beam separation, or diffraction pattern.
Record the observations and compare them with the theoretical wave-optics concept.
Safety note: If a laser is used, never look directly into the beam. Use the diaphragm only under teacher or laboratory supervisor guidance.
Care & Maintenance
Store the diaphragm in a dry, dust-free optics box after use.
Do not scratch, bend, or press the slit area.
Clean only with a soft, dry cloth or approved optics cleaning method.
Keep the diaphragm away from moisture, corrosive chemicals, and rough handling.

Frequently Asked Questions
What is a diaphragm with 2 slits used for?
A diaphragm with 2 slits is used to create two narrow light paths for studying interference, diffraction, and wave optics in physics laboratories.
Can this diaphragm be used with a laser source?
Yes. It can be used with a suitable laser source or ray box, provided the setup is supervised and aligned correctly.
Is it suitable for school laboratories?
Yes. It is suitable for school, college, university, and STEM laboratories where optics experiments are taught under supervision.
What experiments can be performed with this two-slit diaphragm?
It can be used for double-slit interference, diffraction observation, beam separation, and basic wave-optics demonstrations.
What is the slit width and slit separation?
The slit width and slit separation are not confirmed in the supplied data. These values should be added only after checking the manufacturer’s specification sheet.
Does this product include a holder?
The holder is marked as [confirm] because the supplied product data does not verify whether a mounting holder is included.
