USHIO HL63392DG 638nm 200mW Red AlGaInP Laser Diode 5.6mm Package
This 638nm visible light laser diode delivers a powerful 200mW CW optical output (typ.), making it a high-performance light source for laser modules, levelers, measurement tools, and various optical equipment. It combines efficient operation, stable emission, and integrated monitoring for reliable professional use.
Key specifications and attributes (at 25°C case temperature):
- Electrical Performance: Operates with a typical 245mA operating current (max 280mA) and 3.0V operating voltage (max 3.3V) at 200mW output, paired with a 60mA typical threshold current (max 75mA) for low-power consumption.
- Optical Characteristics: Emits bright 638nm light (wavelength range: 633–643nm) in a single transverse (TE mode) oscillation, ensuring consistent, high-quality beam propagation. Its beam divergence is tightly controlled (typical 8.5° parallel, 14° perpendicular to the junction, FWHM).
- Durability & Integration: Features a built-in monitor PD (30V reverse voltage rating) for real-time performance tracking. It operates in -10–60°C temperatures (output adjusts to 120mW at 60°C) and stores safely in -40–85°C environments.
With its compact design, low operating power, and stable single-mode emission, this diode balances performance and practicality for industrial and professional optical device integration.
