21 Jun 2022 LASER COMPONENTS manufacturers low-cost crosshair laser modules for rectangular objects which may be positioned by projecting a cross or two perpendicular lines. However, the single lines must be long enough in relation to the object to guarantee proper alignment. Two crosses at opposing corners of a rectangular shape may define the exact position, e.g. of a label. Cross hair lasers can also be used in medical applications to assist with positioning a patient for a medical examination. In these applications cross hair lasers are provided in 520nm and 635nm wavelength.
