How to get 488nm blue laser light source?
Not as bright as a pure 460nm blue laser light, the adoption of a 488nm blue laser diode module applies a 488nm frequency-stabilized blue laser diode as the laser light source, which achieves scientific research grade. Integrated with an import TEC temperature control system inside the durable anodized aluminum alloy housing tube, it ensures that the laser diode can work stably and output a stable 488nm wavelength laser light source at different ambient temperatures.
Generally 488nm blue laser includes a qualified glass coated lens and focusing lens, which collimate and focus the divergence blue laser beam by the 488nm blue laser diode, thus laser beam becomes a high bright and visible blue dot with ultra compact size, and makes sure of ultra clear and precise dot positioning results onto any targeting surface.
Supported by an AC/DC adapter, 488nm blue laser diode module enables highly stable laser output power, long time lasting blue laser beam and blue laser dot projection from beam aperture. Integrated with APC, ACC driving circuit board, it can prevent overheating and over current impact, thus it perfectly protected laser diode from being damage or burning out due to excessive current or high temperature.
Performance:
488nm blue laser has specific optical properties and energy, which can interact with specific substances, such as exciting specific fluorescent dyes. It is a frequency-stabilized laser which has a power stability (RMS, over 4 hours) of <3%, thus maintaining stable power output for a long time. Some of blue laser module supports TTL modulation, and the modulation rate can reach 0-50KHz, which can realize fast switching control and intensity modulation of the laser. Owing to its low laser beam divergence and good directionality, it always maintains highly concentrated blue laser light source emission and ultra compact size blue dot projection at long extending distance effectively.
Advantages:
488nm blue laser diode module has high monochromaticity, which helps a lot for precise optical measurement in a lot of application fields. Owing to its highly concentrated energy on a specific wavelength, it can effectively excite specific fluorescent substances, and has obvious advantages in fields such as fluorescence imaging. When it gets low laser beam divergence angle, it gets ultra compact size and bright blue reference dot projection with high positioning accuracy, which can be used in occasions where precise position indication is required. In materials science, blue laser beam can be used for Raman spectroscopy research to help analyze the molecular structure of materials.
