ROHM 650nm 7mW Red Visible Laser Diode 5.6mm Package
ROHM 650nm 7mW is a high-precision InGaAlP double-hetero visible laser diode, engineered to deliver reliable performance for sensor applications. Operating at a typical 655nm wavelength (ranging 650–660nm), it outputs up to 7mW of optical power — making it an ideal light source for compact, sensitive sensor systems.
Designed for efficiency and consistency, this diode features a low threshold current (25mA typical) and operates at 33mA (typical) when delivering 5mW output, paired with a 2.3V (typical) operating voltage. Its 0.6mW/mA (typical) output efficiency ensures optimized energy conversion, while the integrated monitor photodiode (with 0.20mA typical monitor current) enables real-time performance tracking.
In terms of beam quality, it offers tight beam divergence (8.5° parallel, 28° perpendicular, typical) and precise beam tolerance, ensuring focused, stable emission for sensor calibration and detection tasks. The compact package (with dimensions outlined in Figure 1/2) supports easy integration into space-constrained designs, while its operational range (-30 to +70°C operating temperature, -40 to +85°C storage temperature) ensures reliability in varied environments.
Whether powering precision sensors or compact optoelectronic systems, the ROHM RLD65NX2 series combines trusted semiconductor quality, 7mW output, and consistent performance — a dependable choice for industrial and consumer sensor applications.
