eBay 405nm "<5mW" pen
Link to product: Best Price Powerful 5mW 405nm Blue Purple Violet Laser Pointer Pen Lazer Light | eBay
Shipping & Packaging
I ordered the laser on October 28th. On eBay it was listed as a possible delivery date between November 4th-November 16th & it got to me November 10th, so right in the middle! Not bad for free shipping from China
The packaging itself is nothing special, just a typical orange paper with bubble wrap on the inside to keep the laser protected. The laser itself was also wrap with a layer of bubble wrap, did it job fine basically!
Laser & how I see it
The laser itself feels pretty sturdy the batteries go in positive side down. It has a much better feeling then a 532nm pen I have in the same host, which is awesome! The batteries in this pen barely rattle which they did on my 532 pen which as you can imagine became a little annoying! My eyes have trouble picking up 473nm, so to me 405nm just looks like a HUGE unfocused violet dot & I need to squint to see the dot itself As most of you know 405 is capable of fluorecense on certain objects! I tried it with my iPhone but Im not sure it picked it up correctly. The laser itself has a danger label with <5mW but as most of you know these are almost always over-spec so I won't be doing any close up burning, sorry.
I don't know the output of this unit as I don't own an LPM but it is much brighter then all my 5mW pens, so I know that's enough to fry my eyes easily if im not careful! The rest of the pictures are just my current rainbow
Overall, if you are new to lasers & just want to get a feel for the common wavelengths eBay is the place to go. They are cheap but they can give you a good chance to experiment with different wavelengths & let you see which you like best. This particular laser only ran me $3 so it was a steal!
