It is a much easier work to make line alignment with red laser line. It is manufactured from 650nm and 625nm wavelengths red laser diode, which is always providing users quite economic and efficient line laser alignment result in all industrial machinery processing works. This type of red laser module begins from high output power of 5mW to 100mW, fulfilling high brightness red laser line projection, thus making great work for improving working efficiency and reducing extremely relying on manual labor strength and professional skills.
