Excelitas launches Point Source LEDs for red dot sights
Excelitas Technologies Corp of Waltham, MA, USA (which provides customized photonic solutions to OEMs) has introduced its SharpDot Point Source LEDs for streamlined integration into red dot sights. The new LEDs are designed to provide long-lasting, enhanced red dot brilliance at relatively low cost.
The SharpDot Point Source LEDs feature what is claimed to be the industry’s highest-efficiency resonant-cavity LED (RCLED) technology, delivering brilliance and very low-power operation to maximize battery life. SharpDot LEDs can be operated down to 15nA for night-vision applications. The five well-defined dot sizes, from 10µm to 80µm, allow for various shooting distances, suitable for red dot and reflex sights.
The product’s matte black housing minimizes unwanted reflections for a uniform dot profile and crisp, clear patterns. Eight standard red dot sizes (20µm, 25µm, 30µm, 40µm, 50µm, 80µm, 85µm and 120µm), custom dot sizes and reticle patterns are available, as well as other dot colors such as yellow and green.
“While all red dot LED designs need to be robust, durable and energy-efficient, every red dot application is different and each customer has unique requirements, so we’ve created an extensive product offering of efficient RCLED red dots to yield a variety of sizes and colors,” says senior product manager Mark Gaston. “Whether your goal is reducing power consumption, clear and sharp patterns, night vision and low-current operation – or all of the above – Excelitas specializes in customer-specific designs to meet the needs of the most demanding applications,” he adds.
The RoHS-compliant SharpDot Point Source LEDs are surface-mountable, enabling easy integration into standard and flexible PCBs. Custom integrated subassemblies utilizing SharpDot are also available.
