Optical Bench Ordinary Physics Lab

Product Code : SCL-LAO-12083

Optical Bench Ordinary Physics Lab (SKU SCL-LAO-12083) is a 1000 mm twin-rail optical bench supplied with riders, a lens holder, an object needle and a ground-glass screen, ready for focal-length and image-formation practicals. It is intended for school and undergraduate physics laboratories. Each bench is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and reaches schools, colleges, tender contractors and distributors without passing through dealers.

Specifications

This twin-rail bench is described in full, one specification per row. In short, two plated steel or anodized aluminium rails, etched in 1 mm steps over 1000 mm, sit on powder-coated cast-iron feet and carry four lockable riders for 10 mm stems, plus a 38–50 mm lens ring, needle and screen.

Applications and Experiments for the Ordinary Optical Bench

Students mount the object needle, a lens and the screen on riders, move them until a sharp real image forms and read the positions from the scale. As school physics lab equipment in India, the bench covers the standard u–v practicals without extra parts.

• Class 12 practical: focal length of a Convex Lens 50mm by the u–v method and the thin-lens equation.
• Class 12 practical: focal length of a diverging lens such as the Concave Optics Experiment Lens, combined with a convex lens.
• Linear magnification of real images at different object distances.
• Diffraction and shadow work with a light source, slits and diaphragms; the Optics Experiment Parallax Pin pair helps with removing parallax.

Tighten the rider locks before swapping glass lenses, and never press down on the centre of the rails.

Standard Scope of Supply

The set includes the 1 m twin-rail frame, two heavy cast-iron support feet, four universal sliding riders with locking thumb keys, a needle-tip object holder, a lens holder ring mount, a ground-glass translucent screen and an assembly guide with student lab templates. Lenses and light sources are quoted separately.

Packing, MOQ and Lead Time

You can obtain a quotation for one bench or for every station in a physics laboratory. It sets out packing, delivery time and price for the requested number, and lenses, mirrors or extra riders can share the quotation so the practical is complete on delivery.

Science Lab Supplies, which holds an Importer-Exporter Code, is able to ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Begin with a note on the contact page, build a combined list in the enquiry cart, or follow the lab tender page for government and institutional tenders.

Frequently Asked Questions

What lens sizes does the lens holder take?
The supplied ring mount clamps spherical lenses and mirrors from 38 mm up to 50 mm in diameter, which covers common 50 mm student lenses such as those used for focal-length practicals.

Will other accessories fit the riders?
The riders accept 10 mm diameter mounting stems, so screens, holders and pins built on a 10 mm stem can be used. Check the stem size of existing accessories before ordering.

Do we need tools to assemble it?
No. The bench uses knock-down joints that are put together by hand with the supplied thumb screws, and the heavy cast-iron feet keep it stable once assembled.

Is Science Lab Supplies a manufacturer or a supplier only?
A manufacturer. This ordinary optical bench is produced in the company's own factory at Saha, Ambala, India, and quotations are issued from there, so the price reflects factory supply rather than a dealer's resale.
