XL-PLPT5 635B-15mW
XL-PLPT5 635B-15mW

The XL-PLPT5 635B-15mW is a single-mode semiconductor laser in a TO56 package (with built-in photodiode). It has a typical emission wavelength of 637nm (red light) and a continuous wave (CW) output power of 15mW (TC=25℃). This device supports both continuous wave and pulsed modes, with a high modulation bandwidth (typically 5MHz), making it suitable for precise pointing, alignment, sensing, and measurement applications that need medium-power red light. The product meets ROHS environmental standards and has a moisture sensitivity level of MSL 2.
