Cube copper diode modules will be really great also for 5.6 and 3.8 mm diodes. Are new size modules only for 9mm diode?

hakzaw1, on ebay seller can abuse buyers if ebay states that buyers have to pay return shipment any case. zone2stealth tried to force me to pay cost of return shipment which is +15$. This could be policy of seller, but it can not be against to main policy of ebay. how do you get this point???

This is the reality, so seller has responsibility to provide enough protection on packet. :banned:

hakzaw, answers of your questions is already in this thread. I got a full refund from seller and just send to him the photo of fully smashed goggle. still I am not happy because destroying something do not make me happy and actually it makes me really disappoint to be needed a safety goggle...

link to seller: http://www.ebay.com/usr/zone2stealth

After open the return claim and discuss in there, the seller suggests me a full refund and photo of fully broken goggle by me, so nothing needs to be return. I accept it because I am bored about it. I am open to suggestion of a safety glass for OD4 and 600-1000nm ranges.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please I think Techhood is best chinese seller on ebay for laser related things. I always got reasonable feedback from him so far and I hope it continues like that. Another thing about Techhood, I recently make...

:beer::beer::beer: to DTR, speaking of a pure experience

I assume something like that but when you check it there is no a clear statement on the webpage of Ebay. This is a bit outward.:undecided: So best thing getting some real experiences from LPF members:beer:

Do you mean open a claim/dispute on paypal?

the seller is zone2stealth, he is a known seller even in this forum. Survivallaser does not have a safety goggle to cover together red and ir range up to 1100nm and shipping cost to Europe :(. This goggle which I purchased is also an eagle pair EP-14.

RedCowboy, thank you for reply. I paid 41$ for goggle and 2$ for shipping. I do not have insurance, i just figure out insurance option. Maybe seller has. Now seller is quite silence, does not reply my last two emails, yet.

I purchased a safety goggle for Red and IR wavelengths from a famous ebay seller, zone2stealth. Unfortunately, it arrived broken frames around blue filter glases at many points from both sides because it was not well packed. I sent the pictures to the seller, he told me he can send new one if I...

You are right, the produced beam is not collimated and the risk is low. When I join this forum, I saw that some people, having limited or non-sufficient knowledge about laser safety, have a few watt laserpointer, it is really freaking me out. :confused::thinking:

Really good points, thanks! Maybe you can add one sentence to mention that some materials under certain laser excitation could be highly luminescent at different/higher wavelength than the laser source, so it may raise a risky situation even if you have proper safety glasses for the wavelength...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please You are right, ultimatekaiser. About SLM violation conditions are mentioned in the datasheet that "longitudinal mode instability may occur due to small changes in drive current, diode-junction temperature or...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please datasheet in the attachment. It says that "The 5400 Series diode lasers operate in single longitudinal mode under some conditions"...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please 5X JDSU 830nm 200mW laser diodes 54-00213 for 45$ on ebay. Link Model number indicates that it is working in single mode. 9$ per diode is really nice price. Update info: Datasheet shows that it is actually...
