BWT Beijing is a joint venture between the United States and China. Utilizing American quality control and Chinese production capabilities, we manufacture fiber-coupled LDs in Beijing, China. Our LDs not only cover a wide wavelength range from 405 to 9XX nm but also come with full support for LD power supplies. Since March 2009, we have been expanding sales in the Japanese market through a distribution agreement with our company, Broadband Co., Ltd. BWT Beijing produces high-efficiency, high-stability, and excellent beam quality diode lasers using our unique fiber optic coupling technology. For laser excitation applications, we offer feedback isolation (>45dB) that blocks return light in the 1040-1100 nm range. By providing high quality at reasonable prices, we contribute to the revitalization of the market. For more details, please download the catalog or contact us. Please note that the catalog is in English.

The positioning green laser has higher visibility compared to conventional red and helium-neon lasers, functioning with approximately eight times the brightness at the same output. It resolves the visual ambiguity that was felt during alignment. The 4-axis compact holder (optional) allows for axis adjustment on its own, eliminating the need for extra adjustment mirrors and their space. Since output adjustment is possible with a dedicated power supply, there is no need to purchase lasers with different outputs for various applications. You can choose the beam pattern from a spot or a straight line. ◆ High visibility, compact high-output laser adopted ◆ Uniform intensity with line beam, not thick in the center ◆ 4-axis adjustable holder eliminates the need for a return mirror 　 (saves total cost and space) ◆ Output adjustment function (output variable from 0 to 8 mW) ◆ Power supply equipped with key switch, power adjustment dial, and interlock *For more details, please refer to the catalog.
