In order to get highly clear and accurate line alignment at great distance, it should be very nice experience to try Berlinlasers blue laser line generator. It is employing 445nm blue laser diode as its beam emitting source. This direct diode emission blue line laser gets special use of inner metal heat sink cooling system inside durable metal housing tube, it achieves superior nice thermal emitting and increasing stability blue line alignment in distance. This blue laser line generator enables easy use in any working occasion. The special use of DC input power supply enables intense and continuous blue laser beam emission and highly clear blue line projection in formal lighting and long distance. It is trying to make clear line projection at great distance. The special use of glass coated lens or separate crystal lens assures high linear quality and highly fine blue line projection. Available with different fan angles of 10 to 110 degree, after correct selection of optic lens degree and easy installation onto desired machine or device, blue line laser makes high precision and high speed line alignment in distance effectively.
