blue laser diode 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 order to get clear and precise enough dot alignment at a longer work distance than formal hand reaching, not easy to reach with a simple blue laser pointer or other manual dot projecting tool at all, it should be a much better solution for users to operate a high density beam emitting device of a 445nm blue laser diode module. It applies advanced blue laser diode tech and a qualified optic lens inside a high duration metal housing tube. In all industrial and high tech precise dot measuring work fields, only after its proper installation onto desired machine or device, this blue dot laser brings users quite easy reaching and long lasting dot alignment for all raw material processing works continuously.

When dot measuring work is processing onto different working surfaces, in order to assure its clear and accurate dot measurement constantly, this 445nm blue laser diode module just applies an AC/DC adapter. It accepts wide range electric current of 100V to 240V, after proper conversion of 5V, 9V 1000mA DC power supply, it is able to make constant blue laser beam and blue dot projection at long extending distance. Every time 445nm blue dot laser gets wide range output power of 50mW to 100mW, unless it is pointing under sunlight, it always makes sure of highly clear and precise blue dot projection within great distance of 25 meters and other formal lighting working occasions as well.

Being made with a qualified glass coated lens and glass window in front of laser beam aperture, in order to assure its clear and accurate dot projection onto various working surfaces, this 445nm blue laser diode module also passes through a series of strict laser beam stability test and aging preventing test up to 24 hours. It is generating highly accurate and highly clear blue dot projection at long extending distance. In practical precise dot measuring work, this 44nm blue dot laser is not only used for industrial dot positioning work, but also making quite satisfied dot alignment for multiple application fields, including laser show, laser displaying, laser communication, laser medical therapy, military targeting and high tech work etc.

Cooperating with electric wires extension for both of 445nm blue laser diode module and DC power supply, not any longer limited by long distance, high height or other hard reaching places etc, it always enables quite easy installation and quick reaching of blue dot indication onto any vertical or horizontal surface. It enables long lasting, low production cost and high precision dot alignment for all machinery processing works. Whenever users are paying high attention to thermal energy hurt to eyes and wearing correct laser safety goggles, this alignment laser just brings users easy and secured dot indication for all working occasions effectively.
