Aiming at the requirements and the current situation of unsatisfied light source production in the traditional mode, an adjusting structure is urgently needed, the structure is easy to adjust in multiple dimensions, low in adjusting difficulty, convenient for batch production and high in reliability, and the problems of low adjusting efficiency and high cost in the industry are solved.
Disclosure of Invention
The utility model aims at providing a structure for laser diode array light beam coupling reflection is adjusted overcomes the shortcoming of the multidimension degree adjustment of not being convenient for in the traditional handicraft, has simultaneously and improves adjustment efficiency, reduces manufacturing cost, advantages such as simple to operate.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides a machinery is from resilient mounting for laser collimation, includes and supports the backplate, install the speculum frame on the support backplate, set up the regulation array installation station along laser diode array quantity direction distribution on the speculum frame, every regulation array installation station is all through the pillar connection angle regulating block, and every is adjusted array installation station and all parallelly connected two adjusting screw that are used for finely tuning the angle regulating block of installation, the positive installation speculum of angle regulating block, every speculum and corresponding laser diode outgoing beam direction of advance 45 settings.
The utility model is used for high-power laser coupling's optical adjustment, the light beam that the speculum sent along high-power laser diode array sets gradually through the microlens direction of advance, the speculum veneer is on the angle modulation piece, the angle modulation piece is fixed in on the regulation array installation station of speculum holder through pillar (screw), then the angle modulation piece also distributes according to laser diode array quantity direction, every speculum and 45 settings of light beam direction of advance, adjust with two adjusting screw on the single angle modulation piece, thereby make the angle modulation piece take place elastic deformation and make light beam reflection direction angle micro-change. In the adjusting process, the adjusting screws on each angle adjusting block are adjusted slightly until the position of the light spot meets the expected requirement.
Because the adoption can produce elastic deformation's angle adjusting block, the partial cementing of flexible shape has the speculum, consequently through the condition of rotatory adjusting screw, can make the angle adjusting block take place the transfer of angle to adjust the direction of laser diode light beam, because the nature of elastic deformation itself, this adjusting device has the function of kick-backing certainly.
The utility model relates to a rationally, fine practical application is worth having.
