No there are not, you only get one lens, 405nm coated, it says it's SUITABLE for both of those wavelenghts. Well actually it does not say, it's implied.

Order and see for yourself

It shows how the lens look like for different ends. Isn't that common sense?

Besides, 405nm lens and 445nm lens are exactly the same anyhow.

You are free to purchase and let us all know

I seriously do not think they give you two lenses with only one module, what's the purpose of the other one that you cannot use ?

Well the unreal dot you get with only one lens (which has 3 optics inside BTW) seems excellent to me.

Susie is not too clued in lasers, and she is trying to tell you that both sides of lens are coated, what she does not know is that inside each brass lens nut are three pieces of optics,

But if you really wanna buy it, then please do. Don't get disapointed when you recieve only one lens though.

Default Re: O-like module 445nm

I wouldn't put a 1W 445 nm diode in this housing, it seems too small for cooling. I wouldn't drive the diode more then 300 mA, or is it made from copper? I think its not.

It clearly stated that the diode is driven at 600mA and driver is fully adjustable and you can set it where you want to.
Heatsink for the diode seems more than adequate.

Default Re: O-like module 445nm

eudamnoium is correct it is just a three stage lens much like the aixiz 405, not two seperate lenses. i believe the performance will be much the same as the aixiz 405, from experience the lenses are much the same

When you spoke about aixiz 405 it's about 1 lens or 3 lenses like this O-like module ?

Hey Firefly...

The O-Like Module comes with one (1) Lens assembly ONLY...
The picture of the 2 lense assemblies is ONLY to show both ends of
the lens assembly in one (1) photo...

Each Lens assembly is made from 3 optic elements (lenses) and a
housing to hold them...

YOU ONLY GET ONE (1) LENS ASSEMBLY....

That's all she wrote.....
