Alpha-One offers the closest service to supply the most suitable optoelectronic devices for each customer; high performance Light Emitting Diodes (LED), Photodiodes, Phototransistors, and other optical devices. One of our feature products is high quality and high power LED with various spectral peaks (from ultraviolet to infrared rays) and packages such as plastic molded type, hermetically sealed can type, surface mount type, and reflective mirror type with excellent radiant intensity (for instance, lp= 875nm: 230mW/sr at IF 50mA). Those LED are suitable not only for illumination purpose, but also for light source in different tasks such as security system, medical analyzer, measuring instruments, optical data transmissions and more. We also offer the LED with special wavelength of 700~850nm including 805nm which is equivalent to the spectral peak of Leaser Diode. Multi-chip LED with different wavelengths in one package is available for the application of sensors according to the specific customer's requirements. Alpha-One supports to design, to develop and to arrange the assembly of various optoelectronic devices. We shall cope with both the trial manufacture with small quantity and the mass-production.
