Optical Spot Reflecting Galvanometer

Product Code : SCL-LM-11220

The Optical Spot Reflecting Galvanometer is a sensitive laboratory current-detection instrument used to observe very small electric currents through mirror-based light-spot deflection. It is suitable for physics laboratories, advanced school labs, colleges, universities, engineering laboratories, polytechnics, research training labs, distributors, and institutional procurement buyers.

Product Description

The Optical Spot Reflecting Galvanometer from Lab Equipments Ambala is best positioned under Physics Lab / Lab Meters / Sensitive Electrical Measuring Instruments. It is used where ordinary pointer deflection may not provide enough sensitivity for small-current or null-deflection experiments.

A dedicated product page with final product code, sensitivity, coil resistance, damping method, mirror system, light source, scale arrangement, suspension type, terminal style, enclosure, accessories, and documentation should be confirmed before publishing. Do not publish unverified current sensitivity, resistance, scale distance, calibration, or certification values without a final specification sheet.

Key Features

• Optical spot indication: uses reflected light movement for sensitive deflection observation where supplied.
• Very small current detection: suitable for null-deflection and low-current laboratory measurements.
• Mirror-based reading: may include a mirror, lamp, optical scale, or reflecting arrangement; final configuration should be confirmed.
• Physics lab compatibility: supports bridge, potentiometer, induction, and sensitive current-detection practicals where suitable.
• High-sensitivity learning: helps students understand how small coil deflections can be magnified optically.
• Educational and advanced use: suitable for supervised college, university, and technical laboratory work.
• Verification required: sensitivity, coil resistance, damping, optical scale, lamp arrangement, and accessories must be confirmed from the final specification sheet.

How to Use the Optical Spot Reflecting Galvanometer

1. Place the galvanometer on a stable, vibration-free laboratory bench.
2. Confirm the current sensitivity, coil resistance, terminal polarity, optical scale position, and circuit diagram before use.
3. Set up the light source and scale according to the supplied optical arrangement, if supplied.
4. Adjust the reflected light spot to the zero position before energising the circuit.
5. Connect the galvanometer into the approved low-current circuit or null-detection circuit.
6. Apply current gradually and observe the movement of the reflected spot on the scale.
7. Record the deflection only after the spot stabilises.
8. Switch off the circuit before changing resistance, polarity, scale distance, or terminal connections.

Safety note: Use the Optical Spot Reflecting Galvanometer only within its confirmed current sensitivity and coil rating. Do not connect it directly across a power source. Use protective resistance where required, avoid mechanical shock, keep optical components clean, and operate the instrument under instructor supervision.

Care & Maintenance

• Keep the mirror, scale, optical window, terminals, and enclosure clean and dust-free.
• Store the galvanometer away from vibration, shock, moisture, strong magnetic fields, and excess heat.
• Do not overload the coil or disturb the suspension, mirror, or damping arrangement.
• Use protective packing during transport to prevent damage to the optical and moving-coil components.

Frequently Asked Questions

What is an Optical Spot Reflecting Galvanometer used for?

An Optical Spot Reflecting Galvanometer is used to detect very small electric currents by observing the deflection of a reflected light spot. It is mainly used in sensitive physics laboratory measurements and null-deflection experiments.

How does a reflecting galvanometer show current?

A reflecting galvanometer uses a mirror attached to or associated with the moving system. When current causes deflection, the reflected light spot moves on a scale, making small deflections easier to observe.

Is it more sensitive than a normal pointer galvanometer?

It is generally used where higher visual sensitivity is needed, but the exact sensitivity must be confirmed from the final product specification sheet.

Does the product include a lamp and scale?

The included accessories are not verified. Confirm whether the lamp, scale, stand, optical arrangement, connecting leads, manual, and protective case are supplied.

Can students connect it directly to a battery?

No. Direct connection can overload the galvanometer coil. Use the approved circuit, protective resistance, and instructor supervision.

What should be confirmed before ordering?

Confirm product code, current sensitivity, coil resistance, damping method, optical mirror arrangement, scale type, light source, terminals, accessories, packing, and documentation.
