Easy measured 650nm red line laser module

What is an easy job to make easy and clear line measurement? It is a popular job to operate a 650nm red line laser module within 5mW to 100mW. The advanced use of metal heat sink and APC driving circuit board are configured with different dimension metal housing tube. It enables easy installation, good beam stability and highly clear red line projection in long lasting use.
The unique use of a qualified glass coated lens and glass window are configured with different dimension metal housing tube. It keeps work with high transmittance red laser light emission, highly straight and fine red line projection within 0.5 meter to 6 meters. Within freely installed distance of 3 meters, not relying on manual labor force input, it assures the best direction and the most efficient line measurement for laser cutting, sand milling, lumber machine, laser car wheel alignment and lab experiment work etc.
