Laser Pen, Red Manufacturer,Supplier and Exporter in India

Laser Pen, Red (Product Code: SLE/PHY/107) is a lightweight red laser pointer used for ray optics demonstrations and simple diffraction work in school and college physics labs. Teachers also use it as a presentation pointer, and its 0.5 milliwatt beam stays on after one press of the button until it is pressed again. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for users of optics lab equipment in India.

Specifications

What Is the Laser Pen Used For?

A narrow, bright beam makes light paths easy to see. Shone through a glass block or prism resting on paper, the red beam lets students mark incident, refracted and emerging rays; aimed at a plane mirror, it shows the angle of incidence equalling the angle of reflection. Passed through a narrow slit or a pair of slits onto a distant wall, it produces a simple diffraction or interference pattern.

Because the button latches, the pen can be laid on a support and left running while the class takes measurements, and a little chalk dust in the air makes the beam visible in flight. Always follow the caution on the listing: never look into the beam, never point it at anyone's face and keep optical instruments out of its path. Teachers should supervise its use at all times.

Supplier

The Laser Pen, Red is supplied by ScienceLab, the trade name of Jain Scientific Equipments Private Limited, Ambala, Haryana. It is sourced for the company's customers and can be packed with prisms, lenses, mirrors and other optics items, so a school receives its whole optics order from one supplier. See our company profile for more about ScienceLab.

• Prism – Glass Rectangular Block — traces refraction and the sideways shift of the beam.
• Prism, Clear Glass — shows deviation of a single ray through a 60-degree prism.
• Mirror, Plane Glass — demonstrates the law of reflection.
• Semiconductor Laser — an alternative laser source for optics experiments.

Frequently Asked Questions

What is the output power of the Laser Pen, Red?
The Laser Pen, Red has a listed power of 0.5 milliwatts. That low output is enough to trace ray paths through blocks, prisms and mirrors in a darkened room, but the beam must still never be viewed directly or aimed at eyes.

Do I need to keep pressing the button?
No. The Laser Pen, Red has a latching button: press it once and the beam stays on until you press it again. This leaves both hands free to position blocks, mirrors or slits and to mark ray paths on paper.

How should the laser pen be used safely in class?
The Laser Pen, Red carries a caution: do not stare into the beam or view it directly with optical instruments. Keep the beam below eye level and away from faces, and let students use it only under teacher supervision during ray optics demonstrations.

What batteries does it use?
The battery type for the Laser Pen, Red is not given in its listing. Please ask through our contact page if you need to know the battery size or want spare batteries included with your order.

Can it be used for diffraction experiments?
Yes, the listing describes the Laser Pen, Red as suitable for simple diffraction work. Shine it through a narrow slit, a pair of slits or a fine grating onto a screen a few metres away to see a pattern of bright and dark bands.

Who supplies the Laser Pen, Red?
The Laser Pen, Red is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab from Ambala, Haryana, India. It can be quoted with prisms, lenses and other optics items so your laboratory order comes from one source.
