Punctiform Lamp
Product Code : SCL-OS-12864
The Punctiform Lamp by Educational Instrument is designed for educational optics experiments where a compact, point-form light source is required. A point-like source helps students observe light propagation, sharp shadow formation, optical alignment, and the behaviour of light when passed through lenses, mirrors, prisms, filters, and optical bodies.
This product is useful for classroom demonstrations and practical physics sessions involving geometrical optics. Exact operating voltage, lamp type, wattage, holder design, body material, base type, and supplied accessories should be confirmed before quotation or tender submission.

How to Use the Punctiform Lamp
Place the Punctiform Lamp on a stable laboratory table or compatible optical bench.
Connect it only to the recommended power source specified for the supplied model.
Position the screen, mirror, lens, prism, filter, or optical body in the path of the light.
Adjust the lamp position until the point-like source is aligned with the experiment setup.
Observe the shadow, reflected ray, refracted ray, image, or projected light path.
Record distances, angles, image positions, and observed light behaviour as required.
Switch off the lamp after the experiment and allow it to cool before handling if it becomes warm.
Safety note: Use the Punctiform Lamp under teacher or laboratory instructor supervision. Do not touch a hot lamp, use damaged wires, or connect it to an unsuitable voltage supply.
Care & Maintenance
Keep the lamp, holder, and connecting terminals clean and dry.

Frequently Asked Questions
What is a Punctiform Lamp used for?
A Punctiform Lamp is used as a small point-like light source in physics optics experiments. It helps demonstrate light propagation, shadow formation, reflection, refraction, and image formation.
Why is a point-like light source useful in optics?
A point-like light source gives clearer ray paths and sharper shadows than a broad light source. This helps students observe optical effects more accurately during demonstrations.
Can this lamp be used in school physics labs?
Yes, the Punctiform Lamp is suitable for school and college physics labs when used under teacher supervision. It is useful for practical lessons on light and geometrical optics.
Does it include a power supply?
The inclusion of a power supply or connecting leads should be confirmed before ordering. Supplied accessories may vary by model or institutional requirement.
What voltage does the Punctiform Lamp use?
The operating voltage should be confirmed from the supplied model’s technical details. It should not be assumed without verified manufacturer information.
Can it be used with filters and lenses?
Yes, it can be used with compatible filters, lenses, mirrors, prisms, screens, and optical bench accessories for standard optics demonstrations.
