About precession scanning
Precession scan heads allow not only the positioning of a laser beam, but also the
setting of the incidence angle of the beam at each point of the workpiece. For a drilling
process, the incidence angle is also called the precession angle. When drilling a
borehole with high precision, the inclination of the internal hole surface, the so-called
taper angle, can only be produced in a reliable and reproducible way if a precession
scan head is used. The production of defined edge angles in laser cutting or laser
micromachining also requires the use of precession heads.
About the PRECESSION ELEPHANT 2 scan head
The PRECESSION ELEPHANT 2 scan head is designed for high-precision laser drilling,
cutting and micromachining applications. It can be used 24/7 in production facilities.
The PRECESSION ELEPHANT 2 scan head offers maximum flexibility for the drilling of
innovative borehole- and edge geometries of differing conicity, taper angles and
shapes, and allows the production of perfectly round, elliptical and custom-shaped
micro holes. The PRECESSION ELEPHANT 2 is available for ultraviolet, green and two
infrared wavelength ranges, each with two different focal lengths.
The scan head can be used with all major ultra-short pulsed laser sources available on
the market today. In addition, the PRECESSION ELEPHANT 2 makes it possible to
monitor the laser process and the laser beam properties during production. The scan
head offers improved particle extraction, beam attenuation control and additional
functionalities designed for mass production of the highest quality. Several other
options, such as tools for the setting and calibration of the polarization, simplify the set-
up of the scan head and minimize downtimes for the end-user.
