What’s The Difference Between Wavelength & Frequency?
Wavelength can be likened to computer hardware. The specific wavelength of a laser diode is determined and set in the manufacturing process and doesn’t change. What is interesting about wavelength is that certain companies will tell you that 635 nm or 830 nm is the “best” wavelength. But what they fail to tell you is that it is very UNLIKELY that their device outputting exactly 635 or 830 on every device with every use.
