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.
Power? Rainbow
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
Final thoughts
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!
