    Handheld Adjustable Optical Light Source

    Our handheld optical light features a 3.5-inch color display and adjustable power output. Supporting up to six wavelengths, it offers a continuous adjustment range of 15dB and the flexibility of single or dual-channel outputs. Paired with compatible power meters, it can automatically recognize wavelengths, streamlining fiber link loss measurements and ensuring reliable results. Its versatile design makes it an excellent choice for both fieldwork and laboratory applications.
