Choose the kit when one bench should cover all three devices and space or budget favours a single panel. The photodiode and phototransistor units are listed with a 0–10 V supply, which gives a wider voltage range for those two devices, so labs that want fuller curves for them, or several groups working at once, may prefer the separate units.
What Is the Opto Electronic Devices Kit Used For?
It covers the core opto-electronics practical in one session. For the LED, students forward-bias it and plot current against voltage to find the knee voltage at which it starts to glow. For the photodiode, they reverse-bias it and record the current at different light levels from the light source; the photocurrent grows with light and changes little with voltage, which is why photodiodes make good light meters. For the phototransistor, the light acts like a base current, so the collector current is larger and rises with light intensity, giving a family of curves similar to an ordinary transistor’s output characteristics.
The kit suits B.Sc. physics and electronics practicals, engineering and polytechnic courses in optical and electronic devices, and ITI electronics workshops. Working through all three devices on one panel helps students compare a light emitter with two light detectors and see why each is chosen for remote controls, optical sensors and counters. Keep room light steady while recording the detector curves, change one variable at a time, and turn the supply to zero before moving leads between devices.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; one kit per bench usually covers a class rotating through the devices.
- Kit or separate units — decide whether you need the combined kit, the single-device units, or both for different practical levels.
- Mains supply — state your voltage and plug type so the power supply can be confirmed.
- Leads and spare components — ask for connecting leads or spare devices in the same enquiry if needed.
Frequently Asked Questions
Which devices can be studied with this kit?
A phototransistor, a photodiode and an LED, all mounted on the panel. The kit is used to study the V–I characteristics of each.
What power supply and meters are built in?
A DC regulated power supply of 0–3 V DC at 150 mA and two round meters for voltage and current. A light source is included, and the supplies, meters and components are connected through terminals.
Why is a light source included?
The photodiode and phototransistor respond to light, so their characteristics are recorded at different light levels. The listing does not say how the light level is varied, so confirm the arrangement with JLab if your method needs a particular one.
Should I buy the kit or the separate apparatus?
The kit puts three devices on one panel with one supply. The separate LED, photodiode and phototransistor units each have their own supply and meters, and the photodiode and phototransistor units are listed with a 0–10 V supply.
What details does an export quotation need?
The quantity, destination country and port or city, delivery terms (for example FOB or CIF), packing or labelling instructions, and a tender reference where applicable.
Who manufactures the opto-electronic devices kit?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronic and physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This trainer is built at JLab’s own works — panel, regulated supply, meters and component mounting — rather than bought from a trader, so colleges, institutes, dealers and importers buy factory-direct, each kit is visually inspected before dispatch, and repeat orders and spares are handled by the maker. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example Bulgaria in Eastern Europe, Algeria in North Africa, Bangladesh in South Asia, Guyana in South America and the USA in North America. Tender information is on the JLab lab tenders page.
