What do you use to make a dome for homemade incident meter?

[Chan Tran]

I have a sensor that I want to use to make the exposure meter. What should I use to make the dome to use it as incident meter? I prefer something small like 10 or 15mm.

For PIR sensors you can buy separate domes. These will probably work perfectly in this application and seem to fit your requirements. The small type has a diameter of about 5mm.

Arts and crafts store didn’t have anything good. I got a broken one from eBay and took the little part of that.

The dome from a household LED lamp is rather large, but it diffuses well.

Half a ping pong ball.

A bit large, but still very similar to a diffusion dome on a incident meter.

Quite opaque, though. You lose a lot of light.

Yes, a trashed Gossen Luna Pro could provide a small incident dome as well...

Yes I think a used dome is a good idea. I have a Minolta dome that has the bayonet broken. I tried it out and it works great. Now I have to figure out how to put all stuff together to build the meter.
