3. Bayanin Tsarin Binning

The product utilizes a performance binning system based on radiant output. This system groups devices according to their measured optical power (Radiant Intensity and Aperture Radiant Incidence) at a standard test current of 20mA. Bins B, C, and D represent different tiers of optical output, with Bin D offering the highest minimum guaranteed output. This allows designers to select components that precisely match the sensitivity requirements of their paired detectors or the illumination needs of their application, ensuring consistent system performance.
