1250~1650nm -25dBm/nm Spectral Power Density Ultra-Broadband SLD Light Source Desktop Type SLD-1250/1650-25-SM-B1
The core of the SLD broadband light source is equipped with a superluminescent semiconductor diode (SPD) chip. Leveraging its unique spontaneous emission amplification mechanism, it can output stable optical signals with low coherence and a wide spectral range, while also boasting the significant advantage of high output optical power spectral density. This light source operates in the 1250–1650 nm near-infrared band, exhibiting excellent spectral flatness and low coherence noise. It can precisely meet the stringent technical requirements of applications such as optical coherence tomography (OCT), distributed fiber optic sensing, and performance testing of passive optical devices, providing a highly reliable broadband light source solution.
