BRM-6401 is a fully automatic beam quality analyzer designed to measure beam divergence angles at the milliradian level and the beam quality factor M². It fills the measurement gap between conventional spot profilers and the BRM-6301 series wide-angle analyzer, making it an ideal tool for analyzing high-quality light sources such as solid-state lasers, fiber lasers, and He-Ne lasers.
With one-click operation in the PC software, the BRM-6401 completes the entire workflow—from beam acquisition and automatic attenuation to M²-factor and divergence-angle calculation—within 1 minute, outputting detailed data including M², fast/slow-axis angular distributions, and half-intensity angles.
Together with the BRM-6301 series, the BRM-6401 forms a full-range divergence-angle measurement solution from milliradians to tens of degrees, covering measurement needs across a wide range of applications.
