“Eye-Safe” 1550 nm Emitters Strengthen Long-Range Ranging Performance

Programs upgrading their rangefinding or precision-guidance modules often struggle to achieve higher ‘eye-safe’ peak power and stronger return signals than 905 nm diodes can provide. After discussing their performance and SWaP constraints with RPMC’s technical team, system designers evaluated triple-junction 1550 nm pulsed diodes, offering higher efficiency and improved return strength in haze, dust, and maritime environments. This allows extended detection ranges and better accuracy, with greatly increased output power and only a minimal increase in power consumption or thermal load.
