Default Re: Help me!

I notice that you have selected a non-rechargeable lithium battery. Why not use a rechargeable CR123? Sure, it has 3.6V instead of 3V, but the driver specified in your first laser can accept up to 6v. Power charts for LOC reds have been posted on the forum.

For your PHR-803T laser, again, the driver can take a 3.6V rechargeable. As far as power output at 110mA goes, these PHR-803T's can vary greatly, you could get anywhere from 70 to 110 mW. It depends on the diode.

For your 6x bluray, a 9V rectangular battery is not the best choice, as it will not support 163mA for very long. This driver would probably run on 2 xCR123a 3.6V rechargeables, these will read about 8.4V at full charge. Or, since this is a lab-style laser, 2 x 18650 lithium, or even a wallwart feeding a 7809 regulator which would in turn power your driver. Many possibilities for powering a labby.

Default Re: Help me!

for the red laser, the optional lense does NOT apply.
those are only for 405nm which is bluray, not the red long open can you chose.

If you would like to get a better lense get a glass lense off ebay AR coated for 650nm.

In regards to the battery life, i don't really know.
For the approx power, there are power graphs around here made by drlava along with a couple other members that could give you a rough estimate.

EDIT:
i just ran across the chart for your LOC(long open can) you will want to pay attention to the solid black line(i think, may wanna double check)

I would look through some of these, surely one of these the dimensions will either match of be close enough:

Default Re: Help me!

Perhaps a small project box, some springs, epoxy, wire, and a connector could be rigged up as an 18650 battery holder. Also http://www.batteryjunction.com/ultra...3a-4-case.html could be useful.

EDIT: This isn't cheap, but is 9v 500mAH http://www.batteryjunction.com/ipowerus-9v-500.html

An alkaline 9V placed under a 163mA load will sag rather quickly in voltage. This lithium might do a little better and is at least rechargeable. 2 x 18650 in a case would of course last far, far longer.
