What is an efficient job for users to make clear and precise dot indication for optical experiment works? It is not able to rely on simple blue laser pointer or other manual dot projecting tool, but substituted by advanced laser diode tech applied tool of a 445nm blue laser diode module. It applies an import 445nm semiconductor laser diode and a qualified glass coated lens inside its durable metal housing tube, which enables high energy density blue laser light source emission, ultra clear, precise and bright blue dot indication at long extending distance and multiple ambient lighting occasions constantly.

445nm wavelength belongs to the blue laser light band, which is always getting high thermal energy, easily absorbed by certain materials, and is suitable for exciting specific fluorescent substances. Being made with a 445nm blue laser diode within 50mW to 100mW and high power range of 150mW to 500mW, in order to make sure of its long period lasted dot positioning work, it has been made with a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube. Not as bright as a 473nm blue DPSS laser system, owing to its direct laser light emission from its inner laser diode, this 445nm blue dot laser alignment tool always gets superior nice heat dissipation, ultra long time lasting and highly stable blue dot indication onto multiple working surfaces conveniently.

Being made with a qualified glass coated lens and glass window in front of laser beam aperture, every time 445nm blue laser diode module is emitting highly bright blue laser beam with high beam concentration and a small divergence angle, facilitating precise alignment with experimental samples or optical components. Cooperated with adjustable focus optic lens in front of laser beam aperture, after its easy roast of laser beam aperture part, blue alignment laser enables immediate blue laser light source concentration, and highly efficient conversion of increasing accuracy and brightness blue dot projection at great distance. It can be adapting to the light intensity requirement of different experiments.

Compared to red laser light such as 635nm or 650nm, the real use of a 445nm blue laser diode module generates higher photon energy, which can exciting wider range of fluorescent materials and extending its applicability. The moderate coherence length meets the coherence requirements of interference and diffraction experiments, ensuring clear experimental observations. In addition, owing to its ultra compact size and durable anodized aluminum alloy housing tube design, available with 16mm and 26mm diameter tube design, this blue dot laser alignment tool enables low power consumption, easy integration into experimental setups, making it suitable for desktop optical experiment system.
