Fiber to Free Space 1064nm Isolator (250W)
A Fiber to Free Space 1064nm Isolator (250W) is a device used in laser systems that transmit light at a wavelength of 1064 nanometers (nm), which is in the near-infrared (NIR) spectrum. It allows light to pass through in one direction but blocks it in the other direction. This is important for protecting sensitive laser components from damage caused by back reflections.
