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

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.

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

Size of Particle Experiment
OBJECTIVES
- To measure the width/thickness of the given samples by analyzing the diffraction pattern.
PRINCIPLE
The characteristics of light such as interference and diffraction can be understood when light is studied as a wave phenomenon. Interaction of waves with matter results in either transmission, reflection, absorption, or diffraction of the wave. When the size of the matter is comparable to the wavelength of the wave that it interacts with, a phenomenon called diffraction occurs. Diffraction of light due to particles is a function of the size of the particle and the wavelength of the light incident. It is possible to measure the size of a particle by studying the diffraction patterns created by it.
KEY FEATURES
- Easy Adjustable Laser: The multiple degrees of freedom on the laser mount helps in the effortless movement of the laser source. This helps in aligning the laser source with the sample quite easily.
- Laser Range Finder: The addition of a laser range finder allows the user to use any standard wall as a screen, increasing the distance between the screen and the sample. Thus, the diffraction pattern can be seen distinctly and thus increasing the accuracy of the readings.
- Multiple Samples can be Tested and Verified: The modular setup helps in measuring the diameters of different samples and other everyday objects as well.

Single Slit Experiment
OBJECTIVES
- To find the wavelength of a given laser using the slit of known width.
- To find the slit width knowing the wavelength of light used.
- Proving the concept of the Heisenberg uncertainty principle.
PRINCIPLE
Diffraction is a phenomenon of bending of waves when it encounters obstacles or narrow opening. A basic setup to observe diffraction consists of a laser, a slit, screen placed at a distance. The wavefronts are partially obstructed by the slit. The intensity distribution of the diffraction pattern consists of a series of light and dark fringes with the intensity distribution symmetric along the central axis. The primary peak is called the central maxima. The corresponding peaks are called secondary, and tertiary maxima. This is studied using the single-slit experiment.
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 with Transverse Saddle: The digital Lux meter enables the measurement of light intensity. The transverse saddle helps in the fine movement of the Lux meter perpendicular to the direction of light.
