Half-Frame Optics Bench

Product Code : SCL-LAO-12084

Half-Frame Optics Bench (SKU SCL-LAO-12084) is a 1000 mm double-rod optical bench, of the half-shaper type, in which one rod carries a 1 mm scale and the other guides the riders, with two riders offering transverse adjustment for lining up optical centres. It serves school, polytechnic and engineering optics practicals. Science Lab Supplies is its manufacturer: the bench is made at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplied from that site to schools, colleges, tender contractors and distributors.

Specifications

The table breaks the half-frame bench into its individual specifications. In short, two parallel plated or stainless steel rods, one engraved in 1 mm divisions over 1000 mm, rest on levelling cast-iron feet and carry four metal riders, two with transverse adjustment, plus two 38–50 mm lens holders and an object needle.

Applications and Experiments for the Half-Frame Optics Bench

After levelling the feet, students place the needle, lenses and screen on the riders and use the transverse riders to bring every centre onto one axis before reading positions. That alignment makes the bench dependable physics lab equipment in India for quantitative lens, mirror and wave-optics work.

• Class 12 practical: focal lengths of lenses and mirrors by the u–v method, for example a Convex Mirror Optical used with a convex lens.
• Linear magnification of real and virtual images.
• Class 12 wave optics and B.Sc.: fringe measurements with the Adjustable Double Slit Interference Apparatus, viewed on a Laboratory White Viewing Screen.
• Engineering tutorials on focal properties and polarisation.

Do not overtighten rider keys on the rods, and keep the bench lightly oiled and flat when stored.

Standard Scope of Supply

Each set includes the 1 m twin-rod assembly, two cast-iron levelling feet with adjustment thumbscrews, four heavy-duty metal riders (two standard and two with lateral adjustment handles), two universal lens holder ring mounts, an adjustable object needle and an instruction manual with setup guidelines.

Packing, MOQ and Lead Time

Request a quotation for a single bench, a 1.5 m version or a full set for each lab group. The quotation confirms packing, delivery time and price for that quantity, and screens, lenses or mirrors can be listed with it so the bench is ready for practicals.

Using its Importer-Exporter Code, Science Lab Supplies can ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions

What does half shaper mean for this bench?
It describes a double-rod layout in which only one of the two parallel rods is engraved with the 1 mm scale, while the other provides guidance. Positions are read from that single graduated rod.

Can components be moved sideways to line up their centres?
Yes. Two of the four riders have transverse adjustment with lateral handles, so a lens or object can be shifted across the axis until all optical centres line up before readings are taken.

What size lenses do the holders accept?
The two universal ring mounts hold lenses and mirrors from 38 mm up to 50 mm in diameter securely, which suits common 50 mm student lenses and mirrors.

Do we buy directly from the manufacturer?
Yes. Science Lab Supplies builds the half-frame bench at its own Ambala factory in Saha, India, and answers enquiries itself, so you deal with the producer from quotation through to dispatch.
