It consists of a 1 1/2 meter long stainless steel double rod optical bench with the following accessories.Lamp house : an electric bulb workable on 220V AC is encased in a metal caseMetal Screen White with cross slit : the slit has one white surface and other black Plane true tiltable mounted mirrorLens assembly consisting of combination of single & double lens holder on a mount rotating on a vertical axis. The Assembly is adjustable in height and can be moved by rack & pinion.
A simple experiment to show transfer of momentum. It consists of metal base with a wire frame. Six identical steel balls are suspended end to end. When one ball is mode to strike the rest of the balls the last one ball is shifted away. When two balls are made to strike the rest of the system last two balls are shifted

It consists of a mild steel frame mounted on a heavy cast iron base fitted with levelling screws, three sliding circular scales graduated in degrees are provided which can be clamped at any position on one of the frame uprights, three pointers for clamping to the test rod are provided
To study Variation of time with length for a compound pendulum. a powder coated steel bar 100x2.5cms bored at every 5cms and provided with 2 removable knife edges. Complete with powder coated wall braket.Available : Steel / Brass Strip
A carefully turned brass disc 125mm dia and 12 mm thickness is provided with split chuck in the center. An aluminium ring of outside dia exactly 125mm has two pins which fit into two cavities in the disc so that edge of the ring is in flush with the edge of the disc.Available : Brass / Iron Disc
Brass C.P. for experiments on rigidity. It consists of a hollow cylindrical brass tube open at both ends with a chuck carrying a mirror. The tube is graduated in mm on both sides, 2 hollow cylinders, all 10cm long, fitted in the bore of the tube, provided with wall clamp
To Find the modulus of rigidity & Young’s Modulus for a wire. The 30cm long wire under test is connected to two brass rods 30cm long. Complete with test wires with connecting screws
Designed to give maximum accuracy with 160mm stainless steel scale divided to 1300, vernier reading 12 seconds, telescope holder is adjustable to the required height, complete with sight tube, one inverting, one erecting telescope and one sun glass.
To determine the value of G. It consists of an electronic unit having four sockets and a switch to help hold or release the ball. A heavy retort stand carries a solenoid. When toggle switch is on Catch position, current flows through solenoid producing a magnetic field and holding the ball. The retort stand carries another base. The ball after being released from solenoid fall s on this base. Time taken by the ball to travel from solenoid to second base is recorded in electronic unit.
