Does this look like a U340 to you?


Recommended Posts

Well, it's not black. It is probably a hot mirror, it looks like it has the typical reddish-pink reflection and greenish-blue transmission.

Looks like they bought a u340 filter. Removed the stock filter from the device and placed it in the sleeve. Then that grad student or postdoc left and someone without knowing what they have is trying to sell it.

Thats not uncommon.

 

Edit the description says it all:

 

"This was in a spare parts cabinet of a large factory laboratory overstock sale that I bought from...... I do not know anything about these, but you should!! "
