When to choose a point, line or cross laser?

Point lasers (also called dot lasers) project a sharp spot of light – ideal for precise single-point marking, distance measurement, triangulation and alignment tasks over large distances. Benefit: all the optical power is concentrated at the point, giving very high visibility even at low power. Line lasers project a line – ideal for cutting lines, paths and boundaries. Cross lasers project a cross from two lines – ideal for centring and 2D alignment. Rule of thumb: point for „this spot here“, line for „along this axis“, cross for „centred exactly on this intersection“.
