• Do not aim the laser at reflective surfaces.
• Classified as Class 2 or 3a according to the label.
• Operates at a wavelength between 630 nm and 680 nm.
• Has a maximum output less than 5 mW, the lower the better.

dependence of wavelength on temperature

Green lasers have up to five times the visibility of red lasers with the same output power

Diffraction causes light waves to spread transversely as they propagate, and it is therefore impossible to have a perfectly collimated beam.
