Our Photo Optic Components line includes both emitter and detector assemblies. Our ELM-3000 and ELM-4000 emitter series include one Red LED at 660nm and an accompanying Infrared LED operating at either 880nm or 940nm. We offer two choices of packaging: clear epoxy molded lead frame and leadless ceramic. Our ceramic (EPM-2001) and lead frame (EPM-4001) photo detectors are spectrally matched to the ELM-3000 and ELM-4000 series, respectively. You may use the pairing table below to conveniently match your needs to our offering.
