445nm blue laser module

Whenever dot measuring work is processing at different work distances, on consideration of high level of accuracy and stability dot indication onto different working surfaces, it should be a quite efficient job to operate a high energy density emitted tool of a 445nm blue laser diode module. It should be operating as an accessory part of those of scientific research used machine or device. Based on the use of correct output power and operating voltage made DC power supply, within the lowest time and energy consumption, this accessory part of a blue dot laser enables quite easy reaching, highly precise and bright blue dot indication for multiple dot alignment and measurement fields.
The real dot measuring work with a 445nm blue laser diode module would be processing for a quite long time. Comparing with a simple blue laser pointer, it gets advanced use of an import 445nm semiconductor laser diode as its beam emitting source, which is available with wide range output power of 50mW to 100mW and high power up to 150mW to 500mW. For the most important of all, in order to make longer time lasting dot projection, blue dot laser gets special use of a metal heat sink cooling system inside its durable metal housing tube. Any time it makes longer time lasting blue dot projection within daily operating time of 8 to 10 hours, it still maintains ultra high level of laser beam stability as expected. 
When high quality glass coated lens and adjustable focus optic lens are integrated into a durable housing tube, available with different dimension metal housing tube, this accessory part of a 445nm blue laser diode module enables quite easy installation and quick reaching of blue dot projection onto multiple working surfaces. It generates high transmittance and high energy density blue laser light source, and converts into ultra precise and bright blue dot projection within long extending distance of more than 25 meters and multiple lighting occasions as well. According to its correct use of output power and operating voltage electric power source, this blue dot laser is able to make quite satisfied dot alignment results for all working occasions.
Based on its featured advantages of monochromaticity, collimation and specific material excitation characteristics of 450nm blue light, it is widely used in the following scientific research scenarios:
Biomedical research
Fluorescence imaging: Blue alignment laser light is used as an excitation light source with a microscope or flow cytometer, which is used for cell labeling, protein tracking and other experiments.
Spectral analysis: Being used as an excitation light source for Raman spectroscopy and photoluminescence (PL) spectroscopy, the band structure and defect characteristics of semiconductor materials and two-dimensional materials are studied.
Physical and optical experiments. 
Chemical analysis and inspection. 
Environmental and Marine Sciences.
Caution: 
Under operation of high power 445nm blue laser diode module up to 50mW, it projects powerful blue laser radiation and reflection from beam aperture. It is a key issue to take active laser safety measure and wear correct 445nm wavelength preventing laser safety goggles until achieving easy, secured and no barrier dot alignment constantly. 

In any type of high precision and high brightness cross line projection at longer distance than formal hand reaching, even though it is not workable at all to rely on any manual labor force input, it should be a much better solution to operate a high density beam emitting tool of a 445nm blue crosshair laser module. It is an industrial stabilized laser device, which makes good use of thermal emitting system and a qualified optic lens inside a highly durable metal housing tube. In various industrial and high tech precise cross line measuring work fields, only after its correct use of output power and optic lens fan angle, this blue cross laser is able to work with high precision, good direction and high brightness blue vertical and horizontal lines generation at long extending distance continuously.

Designed with an import 445nm blue laser diode within 50mW to 100mW, not the same as a simple blue laser pointer only used for temporary positioning work, the genuine use of a blue crosshair laser module is always working for a quite long time, and also having to maintain its stable and reliable cross line projection in use. It is applying an inner part of a metal heat sink cooling system inside a high duration anodized aluminum alloy housing tube. In those of industrial and high tech precise cross line projection work, this blue cross line laser module is bearing wide range operating temperature within -10 to 45 degree Celsius. It keeps work with highly stable and reliable cross line generation for a lot of industrial and high tech work fields.

On the basis of a qualified glass coated lens with different fan angles of 10, 15 and 110 degree, under operation with strict laser beam stability test and aging preventing test up to 24 hours, the usual use of a 445nm blue crosshair laser module still maintains its high level of laser beam stability and ultra clear blue vertical and horizontal lines generation as long as 25 meters and other formal lighting working occasions as well. It emits different cross line lengths within 0.5 meter to 6 meters. In those of industrial and high tech precise cross line measuring work fields, this accessory part of a blue cross laser alignment still makes a good job for laser alignment for screen printing system, heat transfer machine, laser medical therapy, military targeting and high tech work etc.

Within freely installed distance of 3 meters, whatever kind of working surface it is pointing, owing to its 16mm diameter metal housing tube design, this 445nm blue crosshair laser module still enables quite easy installation and quick reaching of blue vertical and horizontal lines generation for both of long distance and long lasting use. For the most important of all, every time blue alignment laser is operating with high attention to laser safety issue, after proper wearing of laser safety goggles, it still brings users easy and secured use for all industrial and high tech fields effectively.
