OPTICAL PROJECTORS

Also known as an optical comparator, a profile projector is an optical instrument that can be used for measuring. It is a useful item in a small parts machine shop or production line for the quality control inspection team.

A Profile projector is widely used for complex shape stampings, gears, cams, threads and comparing the measured contour model. A Profile projector is easy to use and highly efficient. Profile projectors are commonly used measurement of optical instruments. Thus, profile projector is widely used in major machinery & engineering & manufacturing including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels , etc.

The profile projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to examine or measure. This projection screen displays the profile of the specimen and is magnified for better ease of calculating linear measurements.

This projection screen displays the profile of the specimen and is magnified for better ease of calculating linear measurements.

An edge of the specimen to examine on the profile projector may be lined up with the grid on the screen. From there, simple measurements may be taken for distances to other points. This is being done on a magnified profile of the specimen. It can be simpler as well as reduce errors by measuring on the magnified projection screen of a profile projector.

The typical method for lighting is by diascopic illumination, which is lighting from behind. This type of lighting is also called transmitted illumination when the specimen is translucent and light can pass through it. If the specimen is opaque, then the light will not go through it, but will form a profile of the specimen.

Measuring of the sample can be done on the projection screen. A profile projector may also have episcopic illumination (which is light shining from above). This useful in displaying bores or internal areas that may need to be measured. An edge of the specimen to examine may be lined up with the grid on the screen. From there, simple measurements may be taken for distances to other points. This is being done on a magnified profile of the specimen.

Typical Functions of a Profile Projector ;
• Multi-point collection to determine the line and circle;
• Preset the geometry elements;
• Determine the combination of various geometric elements;
• Coordinate rotation and translation;
• Z-axis can be set as length of the sensor or angle value of the encoder;
• User self-programming function;
• Polar / rectangular coordinates conversion;
• Grating linear correction, section linear correction;
• RS232 input function;
• Print page input function;
• Power-off memory function;
• The geometric elements can be stored and call on.
