Default Frankenstein 445nm 2000 mW With 10x Beam Expander By Minamoto

A little demonstration of the tremendous power generated by a 445nm last generation diode. This laser pointer, called "Frankenstein" and realized by the great Jayrob, uses a FlexModP3 driver circuit set to 1.8 amperes and mounted on a generous heatsink. For a better heat transmission between the diode and the heatsink I used the excellent thermal compound "Arctic Silver" paste. I used a pack of three batteries Enerlion 18650 (that uses a high quality Samsung cells) by 3 amps each. Finally, in addition to the factory 405 G-1 lens, I adapted and added to the monstrous 10x beam expander used by the legendary Laserglow Technologies Hercules 532nm. The results You can see with your eyes: a devastating power of 2000 mW REAL AND SUSTAINED, concentrated in a tiny point, that allow to cut paper and card of any color! Even the light yellow paper can be devastated, but it is really dangerous to watch the scattered light without a proper eye protection! This laser can light matches even from the wood side, and turn them on even after dozens and dozens of meters ... just set fire to the infinite and burn the hell! The only flaw it's the prohibitive cost: material plus postages costs will far exceed the 750 dollars! But if you have some pennies saved and You want to get the TOP among the laser pointers, this kit is what You need

Here is the Frankenstein kit thread:

Nice work with the beam expander mod. This still is one of my favorite hosts of all time. It may have been expensive but it will probably be the most memorable laser you will own.

Nice but I read on the laserglow site that this beam expander has 2 mm as maximum input beam width. Usually the 445nm lasers have larger output aperture, at least in the slow axis...

Um so if the expander is reversed you will make a thinner => more concentrated beam, right?

Default Re: Frankenstein 445nm 2000 mW With 10x Beam Expander By Minamoto

Arayan, you're right!
But with the help of the 405-G1 lens, You can find a correct tiny input beam moving the focus of this lens forward or backward.
To obtain a perfect focused powerful beam, You need to have a centered input beam (You can use the same centering procedure of the Hercules host), and a maximum travel of the 10x lenses on the thread, so You can focus very near to the top of the expander or toward the infinite.
The only problem could be that using a too much focused point from the 405 G-1 lens to the first small len of the 10x expander can melt the 532 coating of the len itself.
However, this is not a big problem: the lens are made of glass, and the 532 coating has no reason to exist in a 445 nm laser because has no effects in the output beam. If the coating melt, You can easy remove it with the help of isoprophilic alcohol and a compressor. It's better do not touch the lens with any item, because it's very easy to scratch and damage it!

x Gillza: the beam expander is normally mounted. You need "only" the original 405 G-1 lens correctly focused and the beam expander correctly placed and centered. It's a matter of less of 5 minutes work

Right but what I was wondering is that if you put the expander in reverse, will it become a contractor and make the beam out of the lens thinner instead of widening it?

But with the help of the 405-G1 lens, You can find a correct tiny input beam moving the focus of this lens forward or backward.
To obtain a perfect focused powerful beam, You need to have a centered input beam (You can use the same centering procedure of the Hercules host), and a maximum travel of the 10x lenses on the thread, so You can focus very near to the top of the expander or toward the infinite.
The only problem could be that using a too much focused point from the 405 G-1 lens to the first small len of the 10x expander can melt the 532 coating of the len itself.
However, this is not a big problem: the lens are made of glass, and the 532 coating has no reason to exist in a 445 nm laser because has no effects in the output beam. If the coating melt, You can easy remove it with the help of isoprophilic alcohol and a compressor. It's better do not touch the lens with any item, because it's very easy to scratch and damage it!
Grazie per le infos
