Introduction to Profile Projectors or Optical Comparators

A Profile Projector also called an Optical Comparator or a Shadowgraph Projector is a specialized measuring system that is broadly classified under the category Industrial Metrology Systems. It is a versatile and indispensable measuring system in the manufacturing sector where small parts two-dimensional measurements are required in the R&D, Production, or Quality control departments. Automotive parts, plastic and rubber parts, wire and cable, biomedical equipment are some of the manufacturing industries which extensively use profile projectors for day-to-day measurements.

Profile projectors (optical comparatos) are important for checking rubber and plastic parts in manufacturing processes. They use special lenses and lights to measure the intricate shapes and dimensions of these parts accurately. With features like edge detection and digital readings they help make sure rubber and plastic pieces are the right size and don't have any mistakes. These machines work well for small or big parts helping factories make good quality rubber and plastic stuff.

Profile Projector Working Principle & Construction βŒ„

Optical Profile Projector

An Optical Profile Projector beautifully combines optics, mechanics, electronics, and software to provide small parts two-dimensional measurements.


A beam of parallel light, produced by a tungsten or filament lamp (and with a large enough diameter to provide coverage of the test piece) along with a system of condensers, lenses, and mirrors is used to create and project a shadow of the test piece onto a built-in projection screen. The optical system magnifies the profile of the small part, making it easy to do measurements. Depending upon the light path Profile Projectors are further classified as Vertical Profile Projectors or Horizontal Profile Projectors.

The built-in table on which the test piece is kept is called a work stage that can be moved in x-y directions and has integrated linear encoders to precisely measure the x-y movements which are then displayed on a digital read-out or a computer screen using metrology software.


The operators using their visual acuity and perceptiveness identify and mark a reference point on the shadow (screen has crosshair reference). They then move the work stage along the length of the shadow, the dimension of which is to be measured. Alternatively, they can identify and mark points, and the system automatically calculates the distance, angle, arc length, etc. of the shadow and consequently calculates the same for the part.


The evolution of Profile Projectors led to the invention of Vision Measuring Systems or a video Measuring Machine which uses a digital image of the part (instead of a shadow as in Profile Projectors) and automatic edge detection to do more precise and accurate measurements.

Benefits of Profile Projector βŒ„

The benefits of the Profile Projector are precise, non-contact measurement of component profiles and easy visualization of complex shapes on a screen. It also facilitates cost-effective quality inspection of small, intricate parts in 2D measurement applications.

optical projector benefits
  1. Quick Measurements in 2D space result in fast and accurate dimensional inspections of parts by allowing both length and width to be evaluated simultaneously on a magnified screen.
  2. Imperfection Detection helps identify surface defects and profile deviations, such as burrs, scratches, and dents, ensuring that even minor flaws are detected.
  3. Non-contact measurement ensures safe inspection of delicate, soft, or very small components without physically touching them, preventing deformation during the measurement.
  4. Ease of Use guarantees simple operation and quick setup, as operators can easily position parts, read measurements from DRO or software, and interpret results with minimal training.
  5. Quick Comparison with Standards allows direct profile matching against reference charts, overlays, or CAD-generated templates. It makes it easy to determine whether a part meets the specified tolerances and design requirements.

Types of Optical Profile Projectors βŒ„

  • Classification based on Light Path: Depending upon the light path the Profile Projector can be classified as a Vertical Profile Projector or Horizontal Profile Projector. The former is used for light weight part inspection and the latter is used when the part to be inspected is heavy like shafts etc.
  • Classification based on type of optics: Normally in the profile projector the surface illumination is from sides which sometimes may affect the image clarity in case of deep cavity components. Coaxial Profile Projector as the name suggests has special optics with built in half reflecting mirror in the lenses so the light actually is coaxial with the path of the lenses i.e it comes through the lens thereby making the deep cavity inspection easier.
  • Classification based on Application: If the profile projector is used for comparing the shadow of the work piece with the Mylar or charts then it is generally referred as optical Shadowgraph projector and when it is used with DRO or Software for measurement then it is referred as an Optical Profile Projector.

Simple Optics vs Corrected Optics vs Fully Corrected System βŒ„

In simple optical systems, the image on the profile projector screen is both upsides down and reversed. For symmetrical parts, this system is best suited as there is no difference in both the horizontal and the vertical mirror images.

In corrected optics systems the images produced are unreversed, however, they are still upside down. This system is best suited for asymmetrical parts if it is important to know which side is being measured so that there is no confusion in the operator’s understanding of the measurements.

In Fully Corrected Systems the images displayed on the screen are both erect and unreversed, this makes measuring very convenient for even the inexperienced operators.

Tools used in Profile Projector CalibrationβŒ„

Part of Profile Projector / Optical comparatorβŒ„

Repeated use of Profile projectors over time can make the system go out of calibration. Therefore it is required to re-calibrate them every year. A typical calibration routine involves the following:

  1. Focus squareness parallel to optical axis.
  2. Table squareness perpendicular to optical axis
  3. Perpendicularity of X to Y axis.
  4. Magnification and distortion accuracy for all lenses
  5. X-Y axis lead accuracy for the complete length.
  6. Edge detection accuracy

Frequently Asked Questions

A profile projector is a non-contact optical device that magnifies and projects the contour of a part onto a screen for precise measurement and inspection. Using a light source, lenses, and mirrors, Profile projector displays an enlarged image for accurate evaluation of dimensions, angles, and shapes. Profile projector is widely used in manufacturing and quality control, ensuring components meet exact specifications with micron-level accuracy.

A digital profile projector is used to inspect and measure the dimensions and shapes of various objects. Its benefits include accurate measurements, faster inspection times, ability to overlay CAD drawings for comparison, and reduction in human error during inspection.

To identify verified profile projector manufacturers, look for certifications like ISO standards, check customer reviews and ratings, verify their industry experience and reputation, and ensure they provide warranties and after-sales support.

The profile projector price ranges from β‚Ή90,000 to β‚Ή35,00,000 in India. The equipment cost depends on the brand, model, and specifications.

To buy profile projector from a genuine manufacturer there are many suppliers and traders in the industry which provide cheap low- quality products. But we always recommend the customer purchase profile projector which can adhere to ISO, JIs standards etc. These instruments must be purchased only from a genuine manufacturer which provides prompt service and has a dedicated service team.
