Conventional Laser Scan Micrometer

Enlarged view of the transmitter of the laser scan typeThe motorized mechanism decreases durability and requires maintenance. There is also a concern about laser deterioration due to electrical noise.

TM-3000 Series

Light transmitting lens Enlarged view of the transmitter of the TM 3000 Series[ No motorized mechanism ]
A system with no moving parts provides higher durability. This eliminates the problem of motor durability which has been a disadvantage of laser scan micrometers.

[ Ultra long life LED ]
The GaN (Gallium Nitride) LED used as a light source has achieved high reliability without being affected by light source deterioration due to electrical noise.

Principle

A semiconductor laser beam is projected onto a polygon mirror which is rotated by a motor to scan the measuring range.
The time in which the laser beam is interrupted by the target is measured to obtain the dimension of the target.
