Porthole Glass 2 features dual sheets of high performance optical glass which have been anti reflective coated on both faces to deliver light transmission of over 95% without impacting colour or contrast.
The PHG-2 is a sealed unit which is mounted magnetically to steel brackets that are fixed to the projector opening. This allows the PHG-2 to be easily removed for cleaning or to provide service access to the projector. This also enables the PHG-2 to be easily adjusted for perfect alignment with the finished lines within the room itself.
PHG-2 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.
