This is 405nm 300mW blue-violet laser diode module. It coupled a FC/PC fiber, The output port of the fiber is SMA905 interface, which can be customized. The round blue-violet laser spot. The Numerical aperture of the fiber is 0.22 NA, the full-angle divergence angle is near 25.2°, so the farther the distance, the larger the laser spot. Let’s check it now.
