It is the most convenient line positioning work for users to adopt red line laser alignment. It is the best creation for users when laser tech engineer has just changed a formal 650nm red laser diode into an industrial stabilized line measuring tool, such as a laser line generator. On basis of quite mature laser diode tech with extremely long development history, this red laser module can easily achieve highly stable and reliable red reference line targeting for all long term line measuring works. The employment of 650nm red laser diode is the same as a red laser pointer. However, red line laser alignment is not just workable for simple presentation, but mainly workable for quite clear and accurate line aligning work in all kinds of industrial machinery processing works. This 650nm red laser module employs quite wide range laser lens degree glass cylindrical lens, within its wide laser lens degree of 10 to 110 degree, the desired red alignment laser line is always available with various line lengths and laser beam fan angles. When red line laser alignment is employing qualified adoption of thermal emitting system, no matter the real line aligning work is processed in continuous line projecting work, it is just keeping super reliable performance. This industrial stabilized laser line generator keeps super wide range operating temperature stabilization. Within quite wide operating temperature of -10 to 50 degree Celsius, red laser line alignment is not affected by any working environments. Comparing with formal equipped plastic coated lens or glass lens, in order to get high uniformity red laser line source emitting, red line laser alignment just gets superior adoption of separate crystal lens. No matter what kind of targeting surface, this 650nm red laser module keeps highly uniform red laser beam targeting, and red alignment laser line keeps the same line brightness from middle part towards both ends. Within the maximum line measuring work, this laser line generator is allowing the maximum line aligning distance of 25 meters, users can easily achieve high precision line positioning easily and conveniently. Users can always try to install red line laser alignment on desired machine or device, such as a laser cutting machine, stone, garment cloth, wooden board raw material line positioning and line aligning work etc. According to very simple installation of laser line generator on any industrial device, it can easily get clearly visible vertical or horizontal red alignment laser line positioning as expected. Users should always get secured operation of this laser line module with basic laser measuring rules, it just gets the most satisfied line positioning result clearly.
