Cheapest 445nm available

Whats the cheapest 445nm laser available

For example how much will a 20mW pen cost?

well as a part supplier that would be me.
but as a full working unit self build around 70-100$
buy one pre built 150-225$
Also these lasers only lase above 200mw and can be driven as high as 1.2 (500 recommended)

Are they any pen style <100mW 445nm around

 

[kiyoukan]

they are but they cost more. (the 445nm lasers from casio are all worth the same no matter what power)
Before casio made them they were super expensive and hard to find but now you can get 200mw for the same price as a 1.2W(1,200mw)
due to they all use the same diode.
So if you want parts for a diy i can supply the diode.

I'm still a n00b at DIY. I'll extract the diode from a dvd writer someday when I get laser goggles

What about the CNI 5mW GLP-447 447mW pen

Does anyone know how much that costs? they didn't list a price. Is it >$50

 

[kiyoukan]

Yup it will cost 100's
Sorry to say but the 445nm are being made by hobbyists.
There are a few company's but they rushed their product and made a bad product and they even cost more
