The LZFL405‑80mW‑3 series from Shenzhen Leirte Optoelectronics Co., Ltd. is a coaxial‑packaged violet‑blue single‑mode fiber‑coupled laser diode. It delivers 80 mW continuous‑wave output at 405 nm. Light is coupled into 3 μm core‑diameter single‑mode fiber for clean beam quality and easy integration into diverse optical systems. It serves as a compact violet‑blue light source for medical instruments and industrial printing applications.
Adopting proven TO‑style coaxial packaging, this laser diode features small footprint for OEM embedded integration. The pigtail is 3 μm single‑mode fiber with numerical aperture NA 0.13, standard fiber length 100‑110 cm. Multiple connector options including FC/PC, FC/APC and SMA905 are available for different system interfaces. Its spectral width is 2 nm and wavelength thermal coefficient is 0.3 nm/℃, therefore temperature‑control circuitry is required to stabilize emission wavelength during operation.
Typical electrical parameters: threshold current 45‑70 mA, operating current 125‑180 mA, operating voltage 4.7‑6.0 V, differential efficiency 1.3‑2.0 mW/mA for good electro‑optical conversion performance. All test data are measured under 25 ℃ ambient condition. Operating temperature ranges from 0 ℃ to 90 ℃ and storage temperature from ‑40 ℃ to 90 ℃ for wide environmental adaptability.
Typical Applications
- Medical instruments: Violet‑blue excitation for bio‑fluorescence and photodynamic therapy equipment.
- Industrial printing: Direct plate‑making exposure and lithography‑related industrial devices.
- Extended uses include fluorescence inspection and precision optical instruments for research and industry.
