Next-gen Red Dot RCLEDs from Marktech

These latest 25µm ‘Red Dot’ RCLEDs deliver a 33% increase in optical output power compared to previous generation devices under the same forward current and voltage conditions (If = 5mA, Vf = 2.1V), offering efficiency without sacrificing footprint or compatibility. Ideal for battery-powered systems, the enhanced efficiency translates directly into longer operational life and superior beam clarity.

Available in two robust black surface mount packages – a 2.1 x 2.1mm square SMD and a compact 1.5 x 1.6mm SMD – these RCLEDs incorporate Marktech’s proprietary black encapsulation technology. This advanced packaging eliminates internal reflections and optical defects, ensuring a crisp, well-defined circular point source ideal for the most demanding optical applications.

“Our new high-efficiency 25µm red dot LEDs dramatically improve battery life while maintaining the sharpest, most precise point source in the industry,” said Vince Forte, CTO of Marktech Optoelectronics. “With virtually zero internal reflections and a well-defined beam profile, these RCLEDs provide an ultraclear aiming dot – critical for scopes, speed guns, pyrometers, viewfinders, and finderscopes where accuracy and clarity are non-negotiable.”
