ROHM 940nm 220mW Invisible Single Mode Laser Diode

ROHM 940nm 220mW Invisible Single Mode Laser Diode The ROHM RLD94NZJ7 is a high-precision 940nm 220mW continuous-wave (CW) laser diode, designed as a reliable light source for sensor applications. Built with a double-hetero structure, it operates as a single-mode invisible laser — paired with a built-in PIN photodiode (PD) for real-time power monitoring, simplifying integration into precision sensor setups. Operating at a typical 942nm wavelength (ranging 932–952nm), it delivers a steady 220mW CW output, supported by efficient performance metrics: a 50mA typical threshold current, 270mA typical operating current (at 200mW output), and 2.4V typical operating voltage. Its 0.9W/A output efficiency optimizes energy conversion, while the built-in PD provides a 1.0mA typical monitor current (at 200mW output) for precise performance tracking. In terms of beam performance, it offers tight beam divergence (9.5° parallel, 17° perpendicular typical) and minimal beam tolerance (±3° parallel, ±4° perpendicular), ensuring focused, consistent light delivery. Housed in a compact package, it functions reliably across a -10 to 60°C operating temperature range and withstands -40 to 85°C during storage, with a 2V reverse voltage rating (20V for the PIN PD). Whether powering precision sensors or industrial optical modules, this 940nm 220mW laser diode combines ROHM’s double-hetero engineering, built-in monitoring, and stable single-mode emission to meet the demands of high-precision optoelectronic applications.
