NeoScan™Scanner Inverse Taper Module Inverse taper in the NeoScan™ Scanner† is achieved by rotating a tilted parallel plate about the optical axis while the scanner is operating. Ordinarily, a laser beam is passed through the central region of the focusing lens. The intensities at the focus are so high that the resulting hole drilled either has a small, positive taper or no taper but a bell-mouthed entrance. If the laser beam is shifted off axis, but parallel to the axis, the laser beam enters the material at a larger angle. It is this larger angle that achieves the inverse taper. By adjusting the tilt of the beam offset plate, different degrees of inverse taper can be realized.
The left graphic shows the inverse taper module set with rotating plate a zero degree angle of incidence. This produces a slight positive taper hole as illustrated. The right graphic shows the inverse taper module set with rotating plate at a 45 degree angle of incidence. This produces the highest possible inverse taper as the beam is offset the furthest from the optical axis as shown. This module is made available through Haas Laser Technologies.
