In any type of highly clear and fine line generation at quite long work distance, it is far more enough to use a simple line drawing device, such as a square meter or blocking board. However, there is also no end for laser tech engineer to develop a quite practically used line measuring tool, such as a 445nm blue line laser alignment. It is projecting highly visible and intense blue laser light directly from a 445nm blue laser diode. In various industrial and high tech precise line measuring work fields, on basic of easy use of an external DC power supply and proper mounting onto those of machine or device, this blue laser line generator just assures high level of accuracy and low production cost line generation for all application fields.
Being made with an import 445nm blue laser diode, available with high power up to 50mW, 80mW and 100mW, this blue line laser alignment is projecting highly visible blue laser beam at several miles far away. It is not as bright as a 473nm blue DPSS laser system. On condition that it gets basic use of a metal heat sink cooling system, only after the use of the most compact size tube diameter of 16mm, this anodized aluminum alloy housing tube made 445nm blue laser module assures easy installation, good thermal emitting and highly stable blue reference line projection under multiple working occasions, including mechanical moving or calibration etc. 
Whatever kind of working surface it is pointing, blue line laser alignment is applying for various working environments, and also projecting various line lengths and line finenesses. The adoption of a qualified glass coated lens or separate crystal lens are assuring wide range fan angles of 10 to 110 degree. It is performing well with highly straight and fine blue line with various line lengths. On basis of basic measurement of line length, line fineness and work distance from laser beam aperture to targeting surface, this blue laser line generator just enables correct use of output power and optic lens degree.
Every time blue line laser alignment gets easy installation and adjustment of both laser beam focus and blue line projecting direction within free dimensions, it gets the most concentrated blue laser light, and the most efficient conversion of clear and fine blue line emission as long as 25 meters and other formal lighting working occasions. Owing to its powerful blue laser light emission and thermal energy, it is a key issue to wear correct laser safety goggles, and avoiding eye exposure to beam aperture, this blue alignment laser just makes sure of easy and free line measurement in all occasions perfectly.
