example the electronic circuit components may include without limitation capacitors resistors amplifiers and other semiconductor devices such as an application specific integrated circuit asic the electronic components may be disposed on one or more circuit boards 36 and electrically connected to the laser module 30 and battery electrical contacts 38 40 in order to power and control operation of the laser module 30 as shown in fig1 when turned on the laser module 30 may emit a laser beam 122 at a wavelength of approximately 635 nanometers to 650 nanometers laser beams of other predominate wavelengths may be used in certain applications the laser beam 122 may be a continuous emission or a pulsed emission referring to fig1 the laser module 30 may be independently adjustable for elevation and windage the laser module may be adjusted for elevation by changing the vertical elevation i e the z axis of a cartesian coordinate system of the laser module the laser elevation regulation mechanism 40 raises or lowers the laser module 30 along the vertical axis of the device for example a screw mechanism 40 may be used such that turning the knob 40 or a screw internal to knob 40 clockwise raises the elevation i e increases the value of the z coordinate of.
