Types of Measurements Systems

Thrubeam Optical Micrometer

1D Optical Micrometer

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.
(A) Monitor CMOS The Monitor CMOS tracks workpiece inclination to automatically correct for tilt errors.
(B) High-speed exposure CMOS Proprietary designed measurement CMOS features an integrated amplifier to maximize performance and speed.
(C) Target Position CMOS The CMOS measures the position between the transmitter and receiver
(D) High-intensity Green-LED High-intensity Green LED lasts longer than traditional LED light sources while providing high intensity and evenly-distributed lighting.
(E) High performance condenser Lens unit efficiently focuses LED light

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.

Dual telecentric silhouette-based system

The transmitter emits collimated lighting with a green LED to project a shadow on the CMOS sensor in the receiver.
Measurement is then performed using this captured image. The TM-X5000 Series includes telecentric lenses in both the transmitter and the receiver, ensuring stable, high-accuracy measurement.
