ZLDS104 Series

Laser probes are designed for non-contact measurement and control of the geometric parameters of holes.

It is also possible to order configurations other than those listed below.

The probes make use of an c.w. 660 nm (or 405 nm or 450 nm) wavelength semiconductor laser. Maximum output power is 1 mW. The probes belong to the 2 laser safety class.

-Measuring principle-

The measuring principle is illustrated in Figure. The laser probe is inserted into the controlled hole. The probe or the part is driven in rotation. A triangulation laser sensor, which is built into the probe, measures the distance to the hole surface synchronously with the angle of rotation. The resulting set of polar coordinates is used to calculate the geometric parameters of the hole. Moving the probe along the hole allows you to get the geometric parameters of the hole in different sections and build a 3D model of the inner surface.
