Default Divergence

On Optotronics web page they make an issue about divergence and state that a 1.2mr ad divergence vs. 1.5mrad divergence can make a 56% difference in power at a given distance over 10 feet.

Is this why their prices are higher? *Are most lasers 1.5mrad divergence?

The PPL and RPL seem like a well made laser but the prices are somewhat high, especially for the under 200mw lasers.

If anyone owns an optotronics, I would appreciate some comments on likes and dislikes.

Optotronics also makes a good case for nimh rechargable batteries.

In their RPL series, they use rechargable li -ions.

They have a good reputation, are reasonbly inexpensive and they quote a divergence of <1.2 mrad. This may meet your needs.

1.2mRad is normal. 1.5mRad is what the Wicked Lasers Evolution Series has and it's just for up close burning. It probably has somewhere around 2-2.5mRad seeing as Wicked Laser never actually tells the truth about divergence, along with other companies that just bump the number down to make it look good.

Lucentoptics sells a very good laser. They have excellent customer service, a 6 month warranty, decent divergence, no duty cycle, and their prices are cheaper than any other laser company for more output. I'd say go for Lucentoptics and buy a 100mW when they come back in stock in a few weeks.

Stevetexas,

Thanks for the info, but I am really not looking at the moment.

The 100mw Envee looks like a very good deal for $295.00, and several people on the forum have them I think.

However, if it is comes time for me to "POP" for a burner, I am probably looking at 200mw plus just like youdid! *Im hoping in the next 6 months to one year they drop to under $500.00

I just ordered a 30mw greenie (Atlasnova $79.00) that should be arriving in the next day or so. It is my first purchase.

As a side point, I wonder why Lucentoptics doesn't make anything above 100mw. Seems like if they kept their prices low like they do for their other lasers, they could make a 200mw greenie in the $550 range. Maybe we should tell them!

Been there *I have been talking to them about higher-powered ones for a while now - they are concerned about reliability, heat, etc...but I am sure they will take the plunge, sooner or later !

They must be a newer company or more conservative if they havent figured that issue out and they are worried about liablity.
