About the product

DAYY Photonics’ Superluminescent Light-Emitting Diodes (SLEDs) combine the brightness and power of a laser diode with the low coherence of an LED. Available across a wide range of wavelengths and bandwidths, these light sources are built in industry-standard butterfly packages that meet Telcordia and RoHS compliance standards. Designed for broadband applications, testing, and optical sensing, DAYY’s SLEDs provide reliable performance with superior power and spectral coverage.
