Introduction
In precision engineering, accuracy decides success. From aerospace to automotive and electronics, manufacturers need tools that can measure components with micron-level precision. One of the most reliable instruments for this is the profile projector (also called an optical comparator).
Among the leading names, Sipcon profile projectors have gained popularity throughout Australia due to their reliability, precision, and cost-effectiveness.
This blog covers everything you need to know: profile projector diagram, working principle, uses, advantages and disadvantages, least count, types (Optical, 2D, 3D, Video, Camera-Based), price, calibration, and FAQs.
What is a profile projector?
A profile projector is an optical measuring instrument that magnifies the image of a small part and projects it onto a screen for accurate measurement and inspection.
It is widely used in:
- Automotive – checking gears, shafts, cams
- Aerospace – precision engine parts
- Electronics – PCB inspection
- Medical devices – surgical instruments
- Tool and die making – molds and dies
Profile Projector Diagram
A profile projector diagram helps in understanding the instrument’s key components and their functions, showing how light, lenses, and measurement scales work together for precision inspection.
A standard profile projector diagram includes:
- Light source – projects illumination on the specimen
- Worktable/Stage – holds the object
- Lens system (objective + condenser) – magnifies image
- Projection screen – displays enlarged shadow
- Scales & micrometers—used for precise measurement
This arrangement allows measurement of length, angles, radius, and contours.
Profile Projector Working Principle
The working principle of a profile projector is simple and based on optical magnification. The process can be explained in clear steps:
- Illumination of Specimen
Light from the source passes through or reflects from the object placed on the work stage.
- Image Magnification
The objective lens magnifies the object’s profile to make fine details visible.
- Projection on Screen
The enlarged image is projected onto a screen for comparison and measurement.
- Measurement of Dimensions
Operators use micrometers, scales, or digital readout systems to measure lengths, angles, radii, and thread profiles with precision.
👉 This enables highly accurate inspection of shapes, angles, and contours critical for quality assurance.

Types of Sipcon Profile Projectors
Precision engineering requires different types of profile projectors to meet diverse measurement and inspection needs. Sipcon profile projectors are widely used across industries due to their reliability and versatility. Here’s a detailed overview of the main types:
1. Vertical Profile Projector
The vertical profile projector has a light source that travels vertically from below the worktable. This design is ideal for flat and thin objects such as gaskets, films, and printed circuit boards (PCB). The vertical configuration allows precise magnification and measurement of 2D profiles without distortion. Its compact design also makes it suitable for electronics and plastics industries where space and accuracy are critical.
2. Horizontal Profile Projector
In a horizontal profile projector, light travels horizontally across the object. This type is best suited for heavy or cylindrical parts, including shafts, gears, and cams. Horizontal projectors are widely used in automotive, aerospace, and mechanical engineering sectors because they can handle larger and bulkier components while maintaining micron-level measurement accuracy.
3. Optical Profile Projector
The optical profile projector is the traditional and most widely used type. It relies solely on optical magnification to project the image of a component onto a screen. Known for its high accuracy and reliability, it is ideal for industries that require precise inspection of gears, tools, dies, and mechanical parts.
4. 2D Profile Projector
A 2D profile projector focuses on measuring two-dimensional shapes, dimensions, and profiles. It is particularly useful for flat components and intricate designs, allowing engineers to compare actual parts with CAD drawings or technical specifications quickly.
5. Video Profile Projector
The video profile projector integrates a digital camera that displays the magnified image directly on a monitor. This makes measurements easier and faster, with software-assisted tools for enhanced precision. Video projectors are ideal for R&D labs and quality control departments looking to reduce human error and improve workflow efficiency.
6. Camera-Based Profile Projector
Combining optical and digital technologies the camera based profile projector provides highly accurate measurements with real–time digital analysis. It is suitable for both 2D and 3D inspection, making it a versatile option for complex engineering parts.
7. 3D Profile Projector
The 3D profile projector is designed for measuring three-dimensional shapes and surface profiles of complex components. This type is essential for aerospace, medical, and precision manufacturing industries where surface topology and contour accuracy are critical.
Each type of profile projector serves a specific purpose, helping engineers maintain high-quality standards, achieve micron-level precision, and enhance productivity across various industries.
