15 mm long M9 P0.5 405-450 nm pointer lens

Some time back a few members were looking for 15 mm lens holders, after DTR sold out of them without a source for more. Here's a seller who listed a complete unit with lens:

That's a nice find, Chris, it's been quite awhile since there was a source for these longer lens holders. :yh:

I guess it would be considered a 3 element lens, even though it says they're glued together?

Appears so, I bought something else from this seller and received an auto-response they are on holiday for awhile and will ship later, so if someone wants this, you won't get it quick.

They are now out of stock, so I can't even put them on my watch list. :wtf:

There were only two remaining. Also, heads up if any of you guys saw the 638 nm laser diode listed here; https://www.ebay.com/itm/253407422356 - they are NOT 638, they are infrared, probably 806-808 nm. i received one today and when driven to full output it glows a faint dull pink color, bright white on my BW IR camera.

It seems that they may already be celebrating the Chinese new year which is Feb. 16th this year (next friday).

BTW, It's the year of the dog!
