Laser support for semiconductor laser fixation and laser support element assembly

An apparatus comprising:

• a projection module comprising a plurality of cylindrical housings, each of the plurality of cylindrical housings comprising at least one external aperture;
• a plurality of substantially cylindrical bodies to be inserted into the plurality of cylindrical housings, each of the plurality of bodies comprising:
• a front end having a first aperture having a first diameter to transmit a laser beam produced by a semiconductor laser element, the first diameter to be smaller than a diameter of the laser beam;
• a back end having a second aperture, the first aperture and the second aperture arranged along an axis;
• a first group of windows arranged radially in a first plane, the first plane substantially perpendicular to the axis, at least one of the first group of windows to be substantially aligned with a corresponding one of the external apertures and at least partially fillable with an adhesive to fasten the semiconductor laser element to the body, and each window of the first group of windows comprising an external cylindrical portion and an internal cylindrical portion, the internal cylindrical portion closer to the axis than the external cylindrical portion, the cross section of the internal cylindrical portion to be larger than the cross section of the external cylindrical portion.
