Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced eye safe 1550nm to pulsed laser diodes. Operating a state-of-the-art factory, we specialize in the entire production spectrum—from high-performance chips, TO/F/C Mounts, COS, and MCC bars, to robust stacks and advanced fiber-coupled solutions.
Eye Safe 1550nm TO Pulsed Laser Diodes
Rangefinder systems that are built with 1550 nm pulsed laser diodes (PLDs) also operate at high power levels yet still in the eye-safe range – due to their wavelength. Common night-vision goggles cannot detect this wavelength, which makes these PLDs particularly well suited for military laser rangefinders or friend/foe identification.
1550nm infrared laser mode available in TOpackage and compact structure, provides highly intense and stable IR laser source radiation in the industry. This Pulsed mode 1550nm IR laser diode allows the most efficient and powerful infrared light emitting in all application fields.
