Types of Measurements SystemsThrubeam Optical Micrometer
1D Optical Micrometer
- Principle
- Green LED light is emitted as a uniform collimated beam. When a target breaks this beam a shadow is formed on the light receiving element, measuring this shadow gives us an accurate representation of the target.
Laser Scan Micrometer
A laser is emitted onto a spinning polygon mirror which traverses the beam throughout the sensors measurement range at a constant speed. Measurements such as the outer diameter are determined by measuring the amount of time the light is blocked from the receiver.

2D Optical Micrometer
This optical system uses a green LED and a telecentric lens to irradiate targets uniformly. When a target breaks the beam it creates a 2D shadow on a CMOS, features such as size and angle can be calculated by measuring this shadow. This method utilises the unique advantages of the thrubeam model, which is not affected by lighting, to offer high-precision measurements.
