1 SOLID STATE DIVISION Selection Guide Feb. 2 LED Wide variations of Light Emitting Diodes to match various applications

2 LED LIGHT EMITTING DIODES HAMAMATSU offers a broad lineup of light emitters such as high-power, near infrared LED. HAMAMATSU LEDs LEDs (Light Emitting Diodes) are opto-semiconductors that convert electric energy into light energy. Compared to laser diodes, LEDs offer advantages such as lower cost and longer service life. HAMAMATSU mainly provides high-power, near infrared LEDs for diverse applications including optical switches. Types with a skillfully designed optical lens are used as light sources for high-precision optical encoders. Types with a reflector structure utilizing light emitted from the LED chip edges serve as light sources for spatial light transmission. Application of HAMAMATSU LED Application type / Line-up Optical switch Infrared Ball-lens type Peripheral electrode type Narrow directivity, uniform emission pattern Shadow of wire does not appear in emission pattern. Red type Optical encoder Light source for detection Surveying Optical communication Auxiliary light for CCD Moisture detection Triangular surveying Optical wave rangefinder VICS (Vehicle Information and Communication System) Optical fiber Highly collimated, uniform emission pattern Red/Infrared emission Long- LED, small spot High-speed response, High fiber-coupling efficiency Directional characteristics meeting VICS specifications, integrated emitting / receiving elements For PCF, for GI5 and for POF For detailed information and data on the products listed in this catalog, see their datasheets that are available from our website

3 LED for optical switch Metal package with lens These LEDs have a metal package sealed with a lens cap that delivers narrow directivity. Hermetically sealed packages are reliable even in extremely humid environments. Spectral half width L With reflector Red emission L3989- L9337- * L596-2 * With reflector With reflector High-speed response Uniform emission pattern, narrow directivity L95- * 4.5. General applications L With reflector L L2388- * With reflector GaAs LED Metal package These LEDs are hermetically sealed in a metal package and can be used in extremely humid environments. In environmental conditions requiring high resistance to humidity and temperature cycling, metal package LEDs are ideal. This type of LED has similar characteristics to resin-potted package LEDs.

4 Resin-potted package (with reflector) These are standard package LEDs potted with clear resin. A reflector (cavity) is provided on the metal stem (TO-46) to enhance the light extraction efficiency. The emission diameter is equal to the outer diameter of the reflector.
