This projector provides high durable inorganic polarizer which has a rib shaped evaporated aluminum on the glass surface.
This surface is very delicate. If touching or wiping the surface, the polarizing function will be lost due to damage of the
aluminium rib construction on the surface. Extreme care should be taken to handle the polarizer.
Inorganic polarizer handling
Never grasp the surface or edges of the polarizer with bare hand. If fat and oil on your hand adheres on the
edges of polarizer, the linear bolt may appear on the glass surface due to capillarity. Grasp the edges of the
glass with new gloves or with tweezers when handling it.
Inorganic polarizer cleaning
When removing the dust on the surface, use a commercial (inert gas) air spray or air blower to remove them.
Never use organic solvents.
