Introduction of 445nm blue laser line generator
Typically laser tech engineer has just created blue laser line generator via finished 445nm blue laser diode, but not 473nm blue DPSS laser system. It gets featured advantages of high frequency, high ability of laser beam penetration, high level of laser beam stability, low production cost and long lasting line indication etc. This blue laser gets much shorter wavelength than any formally used green or red laser, thus you will find that blue laser light is easier to be seen by human eyes since it is easier to differentiate for those with a deficiency in recognizing a green or a red laser light.

Usually 445nm blue laser covers two type of wavelength range, including 50mW to 100mW, and 150mW to 500mW. It has been designed and manufactured with different type of tube diameter of 16mm, 18.9mm and 26mm. Integrating metal heat sink cooling system and APC, ACC driving circuit board inside the most durable anodized aluminum alloy housing tube, it obtains excellent thermal stabilization and strong environmental stabilization, which is operating easily and conveniently as an accessory part of industrial device or equipment.

Unique Design of 445nm blue lasers

Adjustable focus optic lens design. The front part design of adjustable focus optic lens enables high concentration blue laser light source emission from laser beam aperture, thus it makes efficient conversion of increasing accuracy and brightness blue line source at longer distance. It allows high precision blue line indication for tasks where moderate level of accuracy line alignment in need.

APC, ACC driving circuit board. Whatever output power it is choosing, either 50mW to 100mW or 150mW to 500mW, this 445nm blue laser module keeps work with constant blue laser beam and blue line projection, without any tube burning out or damage in proper use. It enables long lasting blue line indication and maintains long serving lifetime under proper use by professionals or engineers.

Application of 445nm blue laser for industrial and scientific fields
Comparing with other visible optical spectrum, such as green lasers, this 445nm blue laser line generator is getting less brightness blue laser light source emission with the same output power range. In those of industrial precise line positioning work fields, it is working well as an accessory part of guideline for laser cutting, textile garment processing, saw mill, lumber machine etc.

Owing to its high penetration and high brightness blue laser light source emission, featured by high beam stability and low production cost, this 445nm blue laser module is mainly used for those of scientific experiment fields. It is greatly helpful for biomedical instrument, laser medical imaging, holographic memory, laser microscopy, laser line projection displaying, laser show, inspection and spectroscopic measurement etc.

What is the danger of 445nm blue laser module?

The direct diode emission made 445nm blue laser emits high brightness blue laser light source via a wavelength of 445nm, which is particularly harmful to human eyes. Comparing with other visible lasers among optical spectrum, it gets much shorter wavelength than green and red lasers. It can penetrate human eyes’ protective structure easily.

Any time it gets the use of high power up to 50mW to 100mW, it can easily reaching sensitive retina and cause damage immediately. In order to avoid potential thermal energy hurt and other eye injuries, it is a key issue to wear proper 445nm wavelength preventing laser safety goggles since it can absorb the harmful blue laser light, and protect eyes in the best working condition.
