Ah fantastic! I was hovering over the button for a random ebay seller with one of these bare diodes - Glad you're carrying them Jordan!

I'll place an order soon when I get the cash to do so (y)

Should be a nice looking beam, also have a 120mw optnext coming.

Off topic but has anyone ordered from Opt in Poland lately ? How long was the shipping ? I'm going on 4 weeks here.

very nice Jordan. I have always loved the 638nm color. I wish it was as orange in real as the camera sees. :p

Looking good, Jordan. These should be able to output 280 mW without problems, from what I see here. I do love the single mode diodes. Great beam profiles.

Mine has been going strong for a long time now; over a year. Now that I say that watch......
Does the 250mW diode have your typical MM RED divergence?

This is a great little red diode, it's even bright enough for pointing in the daylight, shows up well against green grass and bushes.

Here's a few pics during some light rain.

driver is set @ 300ma

I've ordered several times from Opt Lasers in Poland. My orders are typically delivered to the US within a week or two. Their orders are trackable. Note that some of their items like RGB modules have a lead time listed on their website. They have met those lead times for me to date.
