Heat Absorbing Glass for Omega D5

[Photo Engineer]

A filament bulb that is used for lighting is a heater that happens to give some light in the process!

All filament bulbs are rich in "heat" which is IR radiation. Therefore a HA glass should be used to reduce heat. An HA glass is mandatory in color to prevent odd artifacts due to IR exposure of the red sensitive layer.

We at EK got several of the early HA glass samples at automotive glass shops, but we went to better glass as time went on. There are many varieties and sources. I bought mine at an automotive glass shop myself.

I mentioned that above.

Dan,

The D5XL was bought about 7 years ago and never used - shamefully sitting in storage (my small apartment not allowing me the room to use it). I've finally arranged for a small space to set it up outside of my own place - this past weekend cleaning, installing a sink, blacking out the space, building tables and print drying racks - getting it all set up. Now I would just like to find a simple piece of HA Glass and find the time to print.


It will be so nice to have my own darkroom again instead of renting space at a communal darkroom.

Here's the answer to my email from Dave at KHB Photographix......

"The 473-103 Rectangular Heat Absorbing Glass for the DV lamphouse is a problem. Apparently Omega is no longer able to supply this item, and we are currently looking for an alternate supplier."

Here's the D5 heat absorbing glass if anyone's still looking, albeit a little pricey.....I still don't think I need it though.

Don't put off enlarging looking for something that you may never find. Use the 75W bulb and start printing. Even if you do find a HA glass, it won't eliminate negative movement. You will need a glass carrier for that. You have to learn how to heat the negative up and focus it just before the exposure to use a glassless carrier with a condenser head. This is "Darkroom 101" stuff.

Think of this heat absorbing glass more like the heat absorbing glass in a movie projector. It keeps your film from burning, not from popping.
