3results about How to "Uniform light intensity" patented technology

This disclosure relates to the field of underwater optical imaging technology, specifically providing an underwater microscopic observation instrument, including a light source chamber and an imaging chamber connected by a focusing mount. The imaging chamber contains an imaging unit for imaging underwater targets between the light source chamber and the imaging chamber. The light source chamber includes a first housing, optical components, and a driving mechanism. The optical components include a laser and a dimming assembly. The laser outputs a pulsed laser beam. The dimming assembly includes a reflector, a conical mirror, and a lens arranged sequentially along the optical axis of the pulsed laser beam. The conical reflector of the mirror reflects the pulsed laser beam, forming a first reflected beam. The first reflected beam is reflected by the inner surface of the reflector to form a conical second reflected beam, which passes through the lens and converges on the optical axis to form an illumination layer. The driving mechanism is used to adjust the position and thickness of the illumination layer to improve the clarity of the underwater imaging of the target by the imaging chamber.

The utility model relates to UV point gum machine technical field discloses a kind of UV photocuring assemblies for LED lamp point gum, multidirectional adjusting assembly includes connecting table, connecting table is fixedly connected in the top of support frame, and working motor is fixedly connected on connecting table, and the output end of working motor is connected with connecting screw rod, and the surface of connecting screw rod is connected with moving seat with screw thread, and the lower fixed connection of moving seat has moving table, and the lower sliding connection of moving table has moving frame, and moving frame is installed in the top of connecting table.The utility model is driven ultraviolet lamp to surround distribution with 120 degrees interval by three groups of sub planetary gears, and the rotation and revolution compound motion of combining planetary gear, so that LED lamp point gum area receives 360 degrees three-dimensional ultraviolet light irradiation, eliminates the irradiation blind area of traditional fixed light source.The constant speed characteristics of gear drive ensure that illumination intensity is uniform, avoid that colloid local solidification is not completely or overcuring, significantly improve product yield.
