The D-beam320 is an optical reflector with 320mm effective aperture. It adopts molding and grinding processing technology and the optical surfaces are coated with high-quality reflective films. D-beam320 uses folded light path to achieve collimation and very narrow beam angle. The minimum beam angle can be within 1 degree. In addition, user can adjust the beam angle by changing the relative position between small reflector in the center and big reflector. D-beam320 is mainly used in the LED beamlight, LED searchlight, etc.
