blue dot laser

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.
