The genuine use of a 405nm violet line laser alignment is not the same as any other visible laser devices, since the purple wavelength of 405nm is at the edge of visible laser light, which has ultra high energy, and can more efficiently excite fluorescent substances. besides its forma operation for those of industrial precise line measurement and alignment works, it is suitable for applications that require fluorescence excitation, such as bioluminescence detection, fluorescent anti-counterfeiting etc.
Structure: 405nm violet laser diode is the core component for generating 405nm violet laser. This violet line laser alignment is usually composed of multiple optic lenses, such as glass coated lens or separate crystal lens based on real line measuring accuracy in real use. For instance, the optic lens’ function is to shape and collimate the violet light beam emitted by the laser diode, convert the divergent violet laser beam into a straight violet line beam with a certain width and angle. On the basis of desired line length, line fineness and work distance, after correct selection of output power, optic lens type and fan angle, this 405nm violet laser module is able to realize high precision and high speed line measurement for multiple raw materials processing works.
In practical precise line measuring works, 405nm violet line laser alignment is able to form a clear and bright straight violet line on the targeting surface, and maintain a high contrast even in strong ambient light, which is easy to observe and identify. Based on the inner cooling system and APC, ACC driving circuit board inside a high duration housing tube, after its operation with superior nice thermal emitting and thermal conductivity, 405nm violet laser module is maintaining high stability of the power and wavelength of the laser output during long term work, ensuring the shape and position accuracy of the straight line.
Cooperated with adjustable focus optic lens design, 405nm violet line laser alignment can easily realize precise optical design and processing. The violet line width can be controlled within a very narrow range, which is suitable for measurement and positioning applications with high precision requirements. featured by small divergence angle of the beam, the energy distribution is uniform, and it can maintain a good beam shape within a certain distance, thus ensuring the clarity and stability of the straight line at different working distances.
