![]() ![]() When this occurs, high stray light suppression performance is required. In situations such as laser SMSR measurement, where multiple optical spectra with different levels are measured at the same time, the stray light can interfere with the measurement. Stray light is optical noise caused by the diffuse reflection of incident light inside a monochromator. In addition, the increased resolution contributes to an improvement in measurement speed and accuracy for low power signals. Wavelength resolution can be varied from 5 pm to 2 nm, supporting a wide range of applications from narrowband peak/notch measurements to wideband spectral measurements. This means a single unit can meet diversifying wavelength measurement needs. The AQ6380 has a wavelength band of 1200 to 1650 nm. Wide wavelength range and variable resolution support multiple applications Signals in close proximity (e.g., residual longitudinal modes of external cavity laser) can be clearly separated and accurately measured. The monochromator has sharper spectral characteristics than ever. Modulated spectrum of 10G optical transceiver It enables to separate closely allocated DWDM channels and modulation side peaks of optical transceivers. The AQ6380 achieves a wavelength resolution of 5 pm. ![]()
