Vacuum Apparatus
Deflection Tube
To show deflection of cathode rays by a magnet. Horizontal tube is fitted with a fluorescent aluminium plate, the cathode side of which is bent at right angle and is provided with a slit. Cathode rays passing through the slit cast a sharp and bright shadow across the aluminium plate. When a magnet is brought near, the cathode rays deflect sharply.
*Additional power supply of 12kV is required to operate.

Vacuum Apparatus
Magnetic Deflection of an Electron Beam
Designed to observe how an electron beam is affected by a magnetic field. The power supply holds a deflection tube with a cathode and an anode. The cathode end features a phosphorous coating, which glows when exposed to electrons. As we bring a magnet (not supplied) near, it causes the electron beam to move in a perpendicular direction to show the deflection of an electron and how a cathode and anode both work.

Vacuum Apparatus
Canal Ray Tube
To show positive rays. Vertical type, with two fused discs at each end and a perforated cathode in the center through which canal rays pass. The space below the cathode is filled with characteristic glow of cathode rays and the upper portion has canal rays. A magnet brought near the upper portion will repulse the rays, showing the positive nature of the canal rays.

Pin Diode Characteristics Experiment
OBJECTIVES
- To study the response of PIN diode, in the following conditions:
- Photocurrent (Iph) vs Applied voltage at constant irradiance (Φ) under Reverse biased condition of the PIN diode.
- Current (I) vs Voltage (V) under forward bias condition of the PIN diode.
PRINCIPLE
The PN-Junction diodes, though versatile, have a few limitations regarding the amount of current they could handle before breakdown and also have low switching frequency, low power handling capacity, and low quantum efficiency. To overcome all these issues PIN diode was designed. PIN diodes are also extensively used as photodiodes in PIN photodiode configuration and are very important in optical fiber communication.
KEY FEATURES
- Precise Optical Alignment: The optical alignment of the components is attained by the optical bench, the set-up time is faster and experimentation is easy.
- Fine and Easy Light Intensity Adjustment: Light intensity adjustment is done via the use of two polarizers. This helps in easier and fine light intensity adjustments.
- Simple and Easy Connections: The color-coded terminals on the various components aid in the ease of connections thus reducing the setup time.

Experiments
Quinck’s Tube Experiment
Objectives
To measure the magnetic susceptibility of a given paramagnetic sample (FeCl3).
Principle
The Quinck’s method is used to determine magnetic susceptibility of diamagnetic or paramagnetic substances in the form of a liquid or an aqueous solution. When an object is placed in a magnetic field, a magnetic moment is induced in it. Magnetic susceptibility x is the ratio of the magnetization I (magnetic moment per unit volume) to the applied magnetizing field intensity H. The magnetic moment can be measured either by force methods, which involve the measurement of the force exerted on the sample by an inhomogeneous magnetic field or induction
methods where the voltage induced in an electrical circuit is measured by varying magnetic moment.Key Features
- Compact Setup – The apparatus design is compact and yet effective to perform the experiments with ease. The simple connections and stand to hold the teslameter probe, makes it easy to handle.
- Custom Quinck’s Tube – Specially designed quinck’s tube can be attached seamlessly on the setup and dimensions are controlled such that it fits perfectly between the pole pieces.

Experiments
Quarter and Half Wave Plate Experiment
OBJECTIVES
To study the effect of wave plates on polarized light
- Quarter wave plate
- Half wave plate
PRINCIPLE
Waveplates are optical devices that resolve a light wave into two orthogonal linear polarization components by producing a phase shift between them. The transmitted light may have a different type of polarization than the incident beam due to the induced phase difference. Commonly used retarders are quarter-wave plates and half-wave plates. The quarter-wave plate is used to convert a linearly polarized input beam into a circular (or elliptical) polarized beam and vice-versa. Half-wave plate rotates the plane of polarization of linearly polarized light that is input on it by twice the angle between its optical axis and the initial orientation of the linearly polarized light.
KEY FEATURES
- Precise Optical Alignment: The optical alignment of the components is attained by the optical bench, the set-up time is faster and experimentation is easy.
- Digital Lux Meter: This enables the measurement of light intensity at various angles of reflection. The meter reads with a precision of 1 lux.
- Easy and accurate adjustments: The design of the setup helps in the easier rotation of wave plates without blocking the path of light. The least o count of 1 aid in accurate readings
