Based on the use of an import 445nm blue laser diode tech, not simply made into a blue laser pointer, it is manufacturing into a more practically used device of a blue crosshair laser module. It applies a short wavelength of 445nm, which can meet the strict requirement of scientific research experiments on the wavelength stability of blue laser light sources and ensure the accuracy and repeatability of experimental results . Under operation with constant electric power source supply and convenient installation or integration with other industrial machine or device, this accessory part of a cross laser alignment tool brings scientific researchers quite precise cross line alignment and observation effectively.
The output laser spot from a 445nm blue crosshair laser module has good uniformity, and the blue cross lines are clear and sharp. Featured by an import 445nm semiconductor laser diode and a metal heat sink cooling system design inside a durable anodized aluminum alloy housing tube, it always gets superior nice thermal emitting and heat dissipation. When it is operating under wide range operating temperature, different humidity and other harsh working environments etc, this blue cross laser still gets no obvious blue laser beam intensity fluctuation or distortion, which is conducive to accurate observation and measurement by scientific researchers.
Based on the use of a qualified glass coated lens in front of laser beam aperture, cooperated with a glass window in front, the genuine operation of a 445nm blue crosshair laser module gets a narrow line width, which can provide pure monochromatic light and reduce the interference of spectral broadening on the experiment. It is suitable for scientific research applications with high requirements for spectral purity, such as high-resolution spectral analysis. According to the selection of different optic lens fan angles of 10, 15 and 110 degree, this blue cross laser alignment emits different dimension blue vertical and horizontal lines with accurate 90 degrees and different dimensions within 0.5 meter to 6 meters length in real use.
Without spending extra time on alkaline battery power source change, only after its proper connects with 5V, 9V, 12V 1000mA AC/DC adapter, this 445nm blue crosshair laser module accepts wide range electric current supply and makes constant blue laser beam emission from beam aperture. Owing to its selected output power of 50mW to 100mW and high power up to 150mW to 500mW, it enables highly clear and precise blue cross line generation within the longest work distance of 25 meters and multiple lighting occasions easily. Owing to its high speed modulation, this blue alignment laser can achieve high-speed modulation, and can quickly switch the laser switch state or adjust the laser intensity according to experimental requirements, which is convenient for time-resolved experimental research, such as fluorescence lifetime measurement.
