Porthole Glass 1 features a single sheet of high performance optical glass which has been anti reflective coated on both faces to deliver light transmission of over 98% without impacting colour or contrast.
The PHG-1 is a sealed unit which is mounted magnetically to steel brackets that are fixed to the projector opening. This allows the PHG-1 to be easily removed for cleaning or to provide service access to the projector. This also enables the PHG-1 to be easily adjusted for perfect alignment with the finished lines within the room itself.
PHG-1 is supplied as standard in a black paint finish but can be specified in specific RAL colours to enable the best possible match with the room decor.
