Laser (for high school) (Product Code: SCL248/040) is a portable green laser that gives a narrow, bright beam for ray optics and wave optics lessons. Its listed wavelength is 550 nm with a power of 5 mW, and it runs either from a stationary supply or from a rechargeable battery, with the charger included. Physics teachers use it to make reflection, refraction and diffraction visible to a whole class. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its laser experiment range for schools.

Aimed at a plane mirror, the beam shows the law of reflection with a precision that ray boxes cannot match; sent through a glass block or prism, it traces refraction and total internal reflection, and a little chalk dust or water mist makes the path visible in the air. Passing the beam through a narrow slit or a fine grating produces a diffraction pattern on a far wall, giving students a way to estimate spacing or wavelength from simple measurements.
Safe handling matters as much as the physics. Never look into the beam or point it at anyone, keep the beam below eye level, remove shiny objects from the bench, and let the teacher keep and switch the laser. Charge the battery fully before practical sessions so the output stays steady. Used this way, it becomes a core part of any optics experiment kit for school laboratories.
This laser is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana business behind the ScienceLab name, which offers optical accessories so that the full ray optics practical can be ordered together. Read about the company on its profile page.

What colour is the beam and how powerful is it?
The laser is green with a listed wavelength of 550 nm and a power of 5 mW.
Is the charger included?
Yes. The laser works from a stationary supply or a rechargeable battery, and a charger comes with it.
What laser safety class does it carry?
A safety class is not stated on this listing. Please contact us and we will confirm the labelling of the unit supplied before you order.
Can students use it on their own?
We recommend that a teacher controls the laser at all times. Beams of this kind can harm eyes, so it should never be aimed at people or reflective surfaces at head height.
Will it fit on an optical bench?
Mounting depends on your bench fittings. Tell us which bench you use and we will advise on holding the laser in line with lenses and screens.
Can it be shipped internationally?
Yes. Send the code SCL248/040, the quantity and destination; shipping arrangements for battery-powered items are confirmed at quotation stage for India and international markets.
