What is a violet laser module?

Violet laser module emits laser light within violet spectrum regions between 390nm and 419nm, which gets the most commercially common available wavelength of 405nm violet light. It gets the shortest wavelength than formally available blue, green, red lasers among visible optical spectrums. It is a short enough wavelength to caused fluorescence in chemical experiment.

The 405nm violet laser module, either constructed by GaN or frequency-doubled GaAs laser diode, is not available at blue laser light, but appears to human eyes as violet laser light, which is a type of laser color human eyes get the least sensitivity than other visible laser devices.

What types of violet lasers are available at Berlin Lasers?

405nm violet lasers covers a large variety of devices, including 405nm violet laser diode, Class II, Class IIIa 1mW, 5mW violet laser pointers, 405nm violet dot, line, cross laser alignments, 405nm ultra compact tube designed violet laser diode module, and 405nm violet diode laser system etc. Supported by alkaline battery power, 5V, 9V, or 12V AC/DC adapter with wide range electric current of 100V to 240V input, it gets ideal environmental stabilization. There are also multiple options of laser type, including violet DPSS laser, fiber coupled, single mode, multi mode violet laser with different packages.

Within wide range output power of 1mW to 1000mW, on basis of real need of presentation distance and lighting occasion, it allow freely choice of output power and electric power source type CW (continuous wavelength) or pulsing laser for real need. It gets particularly designed thermal emitting system and APC, ACC driving circuit board, which ensures constant output power and electric current supply, and no effect by overheating and over current impact as well.

What is the application of violet laser?

The particular type of laser light made 405nm violet laser gets less brightness and beam sensitivity than other visible laser devices. It is getting wide applications for interferometry, holography, confocal fluorescence, DNA sequencing, flow cytometry, biomedical instrument, laser medical therapy for stimulating the sympathetic nervous. Violet laser provides anti-bacterial and anti-microbial properties.

Is violet laser dangerous?

The use of violet laser is extremely dangerous. UV laser can cause immediate skin and eye damage when viewing directly. Human eyes gets less laser light sensitivity to violet or purple color light, thus human always gets slow reaction to such type of laser devices, and causes greater likelihood injury and seriously dangerous to operate blue or violet laser without eye protection.

After users are getting even better illustrate of the dangers, it is necessity for users to avoid eye exposure to beam aperture at close distance. In order to avoid thermal energy hurt and epidemic of ocular injuries of high power handheld violet laser modules, users should take active laser safety issue, such as wearing proper laser safety goggles or install laser safety window on basis of real need so as to assure easy and secured use of different output power level lasers.
