AO - American Optical Series 20 (H20,H21) lamp
Posted: Fri Dec 13, 2019 4:26 am
I recall someone wanting a 100 watt lamp holder for the American Optical Series 20. I have a spare - possible trade for something? These were used in the AO 100 watt lamp housings for the Microstar, Phasestar, and Polarstar scopes of this era.
Conversely, if someone has a spare lamp collector lens for the AO 20 - I'd be interested.
The scope type is as shown here: http://www.pirx.com/droplet/ao20.html
The spare part I have is the black tubular lamp holder with a 3 wire plug. The part I'm looking for is the collector lens immediately in front of this in the microscope base.
