Point Source LED (current constriction type)
<Visible Red λp650nm and Infrared λp850nm>

Point source Light Emitting Diode (current constriction type) <Visible Redλp650nm and Infraredλp850nm>

PRODUCT INTRODUCTION

The Point Source LED’s chip is emitted through a well-defined circular area, typically 50 µm ~ 150 µm in diameter.  Due to this unique structure, no reflection of bonding wire on the light and flat emitting is realized.  The light produced appears as a “spot beam” producing very narrow, almost parallel viewing angles.  This is perfectly suitable for applications which require a near-parallel light source such as high-resolution encoder, measuring instruments and CCD Camera etc,.

Point Source LED with Ball lens
<Infrared λp850nm>

Point Source Light Emitting Diode with Ball lens <Infrared λp850nm>

PRODUCT INTRODUCTION

With ball lens, the point source LED has better coherency.  This LED condenses the high output in the short distance and shows a superior incident radiation rate when they combined to optical fiber or lens.  Well suited to optical transmission, optical communication, Fiber optics and medical equipment. We provide Single lens (ball lens only) type and double lens (ball lens and focusing lens) type.
