Laser colors. What are the differences, what color should you choose?

A Nivel System expert explains the technical differences between the various models of crossline lasers. He will also advise which laser is most suitable for the work to be carried out.

RED LASER

• 535 nm – wavelength of light
• the most economical – cheaper than other beam colors
• recommended for working in less sunny rooms
• outdoor work – the use of laser sensors is required

GREEN LASER

• 515 nm – wavelength of light
• the most popular because it is more visible in bright rooms (4 times more visible compared to a red laser)
• outdoor work – the use of laser sensors is required

BLUE LASER

• 505 nm – wavelength of light
• similar in color to the green beam (this is due to slight differences in the wavelength of light) – which ensures comparable visibility
• very well cut off by the edge of the beam – it is slightly thinner than the green one
• affects the comfort of work – the beam is clearer and not overexposed
• recommended for all works requiring high accuracy
• outdoor work – the use of laser sensors is required

VIOLET LASER

• 450 nm – wavelength of light
• visibility comparable to green and blue beams
• very well cut off by the edge of the beam – similar to the blue beam
• affects the comfort of work – the beam is clearer and not overexposed
• recommended for all works requiring high accuracy
• stands out perfectly on the construction site, surrounded by other beam colors
• outdoor work – the use of laser sensors is required
