I am curious as to the price a 445nm focusable laser would cost.

Power isn't going to change the cost (since it is all the same diode) , but 900mw-1100mw.

around 100$
laser 38-45$
Lens 10$
Driver lm317 5$
Heatsink 10-20$
host 3-25$
axiz housing 2.25$

That's a very conservative guess. My 18650 laser with copper heatsink and really good battery cost probably $190 (including things like goggles and thermal paste though).

Well its not a guess, i have made 3 445nm lasers all around or under 100$
i dont include goggles in the price of a build because you dont need a pair with every build they are a on time buy.
Thermal paste is adding an extra 5$.
And depending on your host you can use any old flash light or project box to a pure silver host.
The laser itself has a set range on its price too.
it seems the last component that could vary widely in price is your heatsink.
at 190 just seems like you paid alot.
where do you get the other 90$?
copper heatsinks are maybe 40$ max. maybe a bought driver for 30$ Battery and charging system takes the rest?

All of this is including shipping-
Host-47
Microboost-25
copper heatsink-12
diode-50
lens-10
aixiz module-2.5

total-146.5

extras (thermal materials$7+case$8+goggles$8+AW 18650$21)-$44

total-190.5

And as for what you said, you can't really use an lm317 driver in a flashlight host.... I HATE labbie hosts, your $100 price would make sense for a labbie. The cheapest handheld I could think of would be in a pen host, which would end up being around $100 probably.

Well lm317 can be built very small about the size of the whole 317 chip

But you can't drive a 445 diode off an 18650 with an lm317 sadly, you need a boost driver.
