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.
Material analysis field. 405nm violet laser can be used for analysis of semiconductor materials and nanomaterials, which can study the optical properties and defect states of materials, such as study the energy level structure and carrier recombination of nanomaterials by analyzing fluorescence spectra.
Environmental monitoring field. Violet laser light source can be used to detect pollutants in water and heavy metals in soil. For instance, fluorescent substances in water can be excited and the type and concentration of pollutants can be determined by spectral analysis.
