We are dedicated helping you been satisfied from the specified product you ordered
Our mission is to make our customers’ experiences working with us enjoyable and completely positive and satisfactory.
We work continuously for almost 18 years with our high-tech manufacturer and partner, in specializing of developing, designing, producing and selling series of laser products internationally.
Our laser products include Belt / Sheave Laser Alignment tools, red, green, blue laser module, HR Optics, laser sights, laser bore sights, laser pointer, custom Lasers,
We supply to the manufacturers who produce tools and equipments such as electric tools, electrical machines, carpentry sawing, needlework, leveling instruments etc. We can also be supply to the electronic tool manufacturers who measure distance by taking advantage of the two and for laser phase and the temporal change.
Meanwhile, they can be used as laser illuminant by manufacturers who produce gift or lighting.
We have already designed and produced multiple semi-conductor lasers which are of different use, e.g.: special line type laser head that is used to level laser line marker automatically, special laser head for bar code scanner, high-accuracy laser, high-brightness red laser etc.
Our products are mostly semi-conductor laser of technical grade. We can offer our consumer photo electricity solution, design and produce semi-
conductor laser of special use and special laser optical system etc. Products that we supply are of high stability, good coherence and a long working life.
We have already developed and produced 6 main series and more than 120 kinds of semi-conductor lasers, industrial laser modules, industrial markers, laser illuminant, teaching and laboratory deductive laser systems adjustable lasers, cryogenic modules, laser line markers and some other products which are derived from laser, including visible light wave band: 635nm 5mw-30mw、650nm 5mw-70mw、670nm 5mw-50mw. These products have been applied to multifarious electronic tools, devices and equipments for positioning instruments, laser distance finders, laser levels, laser line markers (laser line projectors), laser direction indicators, bar code scanners, laser sighting pieces, laser medical treatment instruments, analyzers, laser level bars, stage lighting and landscape engineering etc.
Now we have already comprehensively adopted domestic advanced testing and production equipments. We also attach great importance to technical reformation and continuously introduce vanguard technology and equipments to ensure the quality of our products. In order to achieve the quality assurance which we promise and to meet the requirements of ISO9002 quality assurance system, we strictly implement management process and assure fine quality.
We will guarantee that each product satisfy our clients and provide the most reliable products and best satisfied before/after-sale service to our clients unconditionally. We insist in “honest business and high quality service” as our business ideal, with a powerful R&D team and a group of skilled workers in the factory as the strong backup and support, we always work on this ideal to serve all customers with good quality and reasonable price.
