405nm violet laser diode module is at the blue-violet end of the visible optical spectrum and can produce specific interaction with a lot of substance, which enables high resolution detection and imaging results for multiple application fields. Although it projects less brightness violet laser light source than other visible laser devices, however, it gets quite high energy in use. It is sufficient to excite a variety of substances to produce fluorescence or other optical effects, which is conductive to the detection of weak signals.
The usual use of 405nm violet laser diode module gets good laser beam quality, featured by high brightness, narrow line width, low noise, which is able to provide a stable and accurate excitation blue laser light source effectively. It applies qualified semiconductor laser diode with different output power range, thus it has been integrated into a quite small size tube with low thermal consumption. It is easy to integrate into various spectral analysis equipment so as to meet the application needs of different scenarios.
After quite easy connects with an AC/DC adapter, 405nm violet laser gets high sensitivity, which can detect low concentration substances easily. Owing to its superior nice selectivity, it can specifically detect target substances by selecting appropriate fluorescent probes or analyzing specific spectral features. Within the lowest time consumption, violet laser light source obtain spectral data with high speed analysis speed, small damage to samples, especially suitable for non-destructive analysis of biological samples. Usually the instrument is relatively simple, which is easy to operate and easy to automate.
Applications of 405nm violet laser diode module:
Biomedical fields. in cell imaging experiment work, 405nm violet laser light source is used for fluorescent markers such as DAPI can be excited to help observe cell structure and internal activities. In flow cytometry, fluorescent dyes can be excited to analyze and identify cells. Violet laser beam can also be used for biological detection work such as DNA sequencing and protein crystallization so as to excite specific fluorescent substances accurately to obtain information about biological molecules.
Gem identification field. Under 405nm violet laser excitation, impurities or crystal structures in different gems will produce unique fluorescence spectra, which can be used to identify the types of gems and determine whether they have been optimized. For example, violet laser light indication can be used to identify whether diamonds are natural or to detect whether emeralds are oiled.

Review of 405nm Violet Line Laser Module
In order to make highly clear line alignment at quite long work distance, it might be very hard job for users before selecting a quite professional line measuring tool correctly. At the same time, on basis of continuous technical innovation of 405nm violet laser diode and qualified optic lens with different fan angles, it is just being made into a quite practically device of 405nm violet line laser module. When compact structure made IR laser line generator gets continuous electric power source from DC input power supply, and selects correct output power and fan angle, it is just making highly clear and easy line indication onto all targeting surfaces effectively.
Not the same as any other visible laser devices, 405nm violet line laser module is only employing 405nm violet laser diode as beam emitting source. It gets a bit longer wavelength than UV lasers, thus always projecting moderate brightness violet laser light from beam aperture. It gets wide range output power of 50mW to 100mW, on consideration of continuous violet laser line projection, this laser line generator gets basic use of inner cooling system. According to special use of metal heat sink cooling system inside 16mm diameter metal housing tube, it achieves superior nice thermal conductivity and increasing stability violet reference line projection in continuous use.
According to quite special use of a qualified glass coated lens, not the same as a simple plastic coated lens, 405nm violet line laser module achieves high linear quality violet reference line projection from beam aperture. It enables freely selected fan angles from 10 degree to 110 degree, which just achieves different line lengths within 0.5 meter to 6 meters. It should be passing through basic measurement of line length, line fineness and work distance, after correct measurement and experiment, this line laser alignment achieves high precision violet line projection in distance effectively.
When line alignment is processing at various work distances, 405nm violet line laser module enables freely selected output power of 50mW to 100mW. The special use of APC, ACC driving circuit board is making perfect protection of alignment laser from any possibility of burning out or damage, and achieving extremely long lifetime and highly stable violet line alignment continuously. After quite easy screw of adjustable focus optic lens, the most powerful and intense violet laser light is converting into highly clear violet line in distance. Under high attention to laser safety issue and correct wearing of laser safety goggles, this violet laser achieves safe and clear measurement perfectly.
