Infocus X1 Cracked lamp lens

john65b · 16th May 2009, 11:57 AM

Hey all, I have used an Infocus X1 for a long time (over 5 years) and recently realized that the lamp was very dim. I removed the lamp with housing and cleaned all that black silt as I have a couple other times since buying it.

Anyway I notices the small square glass lens on the housing (not the main projector lens) has a visible crack. I am sure this is the main reason for the dim projection as all the light must pass through this lens .

Can this be fixed? Anyone know where a replacement can be found? I am sure this is a heat barrier of sort and the projector cannot be operated without it.

Any help would be good.

Thanks

Anyone?

Is this lens on the lamp housing (not the main lens) the condenser lens? I have read somewhere it is plastic, but can find no more information on it at all...

Maybe this is just a UV filter? Heat Shield?

I am thinking of trying the projector without it to see how clear and bright it would be...

The small square lens redish in color is the UV filter the dim light is from the light tunnel mirrors collapsing. Somewhere here I have a thread on how to fix it. The crack in the IR filter dont effect brightness that much. 99% sure its the light tunel....It happened to my X2

I'm not an expert on projector optics by any means, but in the theatrical world heat shield glass used in lighting is often in two pieces so the glass can expand as it heats up. Same principle as expansion joints in roads/bridges.
