Best Profile Projectors in India
A Profile Projector, also known as an Optical Comparator, is a precision measurement instrument used in manufacturing and quality control to inspect the dimensions of small mechanical parts. These devices provide high accuracy (±0.001mm) by magnifying the object onto a screen and comparing it with a standard overlay or CAD data.

What is a Profile Projector?
A Profile Projector is an instrument that magnifies and projects an object's profile onto a screen for precise measurement. It helps manufacturers ensure high accuracy and consistency in components like gears, screws, and machine parts.
How It Works:
- Light Source: A halogen or LED light illuminates the object.
- Magnification Lenses: The image is enlarged (10X, 20X, 50X, or more).
- Projection Screen: Displays the magnified profile.
- Measurement Tools: Digital readout, micrometer scales, or software for data analysis.
Common Applications:
- Automotive – Measuring pistons, bearings, and engine parts.
- Aerospace – Quality control of aircraft components.
- Medical Devices – Ensuring precise dimensions of surgical tools.
- Electronics – Inspecting PCB layouts and connectors.
