Product Code : SCL-LAO-14593
The Optical Needle, also known as a Parallax Pin, is an essential instrument used in optics experiments to demonstrate parallax and error in measurement. It helps students accurately understand apparent shift of objects when viewed from different angles, which is a fundamental concept in geometrical optics.
It is widely used in schools, colleges, engineering labs, and TVET institutions for experiments like:
- Parallax error determination
- Accurate reading of scales
- Alignment and sighting in optical benches
- Studying measurement techniques in physics
The apparatus typically consists of a fine metallic pin mounted on a base that can be adjusted along a scale to show parallax shift relative to an observation scale.
Key Features
- High-Precision Optical Pin for minimal diameter and accurate sighting
- Stable Base to prevent movement during experiments
- Adjustable Height & Positioning for accurate parallax demonstration
- Durable Metallic Construction ensures long-term use
- Clear Markings on base for measurement reference
- Compact & Lightweight for easy classroom handling
- Ideal for Physics Lab Experiments in optics and measurement
