Yes I think it is, I can tell that it must be a new listing because it has an abvious typo 'whit' (they meant to type: with) I viewed their product 15 minutes after I got your message.
This is exciting. Ill place an order for one in the very near future.
There has been an update from the seller, they sent me an official datasheet for the FAC Square Output Beam NUBM0C Laser Diode, and said they are going to list the product and send the link to me.
Here is their message with the datasheet:
Good choice, it is quite power efficient and 1.2 watts of 638nm is the same visual brightness at 3 watts of 445nm laser light, also has Good Divergence compared to most common un modified high power Red Laser Diodes noting that the most visible wavelength to the Human eye is 555nm.
The best...
Absolutely, they are fairly sharp really compared to standard lds for their power output, styropyro on youtube and discord made a mini laser with a 1.2W 638nm FAC LD from I think Lasertree on ebay, and it has one tight beam for that Diode especially
I bought an nugm04t FAC square spot Laser Diode Recanned and gas filled from 'optics LD' on the bay, I used a DTR G8 Lens which has an 8mm FL, it is damn sharp compared to the raw output from an unmodified one, but there was still a slight rectangular shape at distance, but i put it through a 3x...
I Discussed modification of the 'NUBM0C' Sky Blue 465nm, 4.1 Watt Laser diode with an e bay seller
(Laser Tree) who supplies modified laser diodes to companies and individuals, they stated that they will sell said Laser Diode Upon Request (I don't know if or when it will be listed as a product)...
