Tips for buying a red laser module

The wavelength of the red laser module is usually 635nm / 650nm / 660nm, and the power range is from 1mW to 2000mW. For a 650nm laser module of no more than 200mW, the price is relatively low. If you need better visibility, we recommend you choose a 635nm/638nm red laser module, but the price will be higher. Many parameters are customizable: operating voltage, product size, output power, wavelength, dot/line/cross, extension cable, etc.
