This GB seems really promising, especially since the lenses available to everybody right now are almost the worst possible to use with BR.

So as long as the price is good with everybody, it looks like you have yourself a nice GB!!

Yeah, i thought it would take too long, that's why i started the feeler before the actual testing. But it would seem to be gathering interest quite fast.

Now let's just hope the lens works really well..

Well we already have interest in 60-80 lenses so far. What kind of discount do you think they might offer you?

Just a note, Since everybody is listing thier preferance, I would prefer my lenses to be mounted into a "nut" as well. ;D
Thanks again,

I think Igor will post this type of information as soon as he knows. As he has said, this is all pending his testing, if they show a real advantage. That testing will come first - then he'll decide whether to buy, and will persue discounts then. Meanwhile it would help him if we are patient and let him go at his pace - he's a busy guy and is doing this work just to help us out.

Dark_Horse:

If it is not mentioned separately, i will assume the lens is supposed to be mounted in a nut. If someone wants a bare lens, please mention it. But there is still time to decide on this later.


We are going to need MANY lens nuts, if this works out. If someone knows, where to get just the lens nuts (with a clear acrylic lens i guess), please let me know.



Midknight:

I don't know about the discounts yet. I will have to ask when we know the number. Did you count 60? I am way too busy at the moment. I barely have enough time to add names to the list..

Once i get the invoice for my sample lenses, i will ask what quantities they give discounts on, and then i'll have to make a careful calculation, so i don't end up losing money over this.


It might also be good to have someone reliable from the US, to do the distribution there, so i only have to ship once, and people can save on shipping cost.


But we are not there yet. First, the samples have to be tested.

But yeah 60 for sure. If the price is right, then about 80. And thats just right now.

Ya know I've shone the light unfocused with any lens and the results are interesting. Making sure I get all the light put out from the diode onto the sensor, my bluray puts out 120mw. With a clear acrylic lens it puts out 106mw. So the acrylic isn't loosing that much.

Default Re: 405nm AR glass lenses - fit AixiZ  FEELER

I did that as well, but i get 120mW when there is 91mW after an acrylic lens.
And this would fit with Jayrob's results from the Meredith lens, that puts out 117mW, when there is 90mW after an acrylic. He measured a 30% increase from acrylics at various powers, when he put a Meredith in.

So there should be room for 30% of improvement. But only testing will tell for sure.. As i said, this thing ain't starting until the testing results are in, verified by several people. Then everyone can decide if they want the lens or not. This thread is just to figure out how many people would be interested, if it works, and what the price would be.

I'm not promising anything, other than that i will buy and test the samples, and if they test good, make sure others can get them too.


BTW, did you have the diode in a module, when you did that test? What current was it set to?

Remember, all calorimeters and energy meters have a +- accuracy percentage. In addition each diode has the potential to be different.

In any event, 120mW to 106mW is still a loss of over 11%. I'll grant it's not 30%, but it's still significant.

The accuracy does not matter, when making a relative comparison. As long as the response of the meter is linear, a relative measurement will always yield the correct percentage.

The problem with this is that it is hard to tell how much power is coming from the diode, if it is in an AixiZ module. Part of the light cone hits the inner walls before it can escape.

And then, the measurement can be influenced by the distance of the diode.. The closer you bring it, the more you measure, even tho the entire light was covering the sensor from the start. This is because the thermopile can measure the heat coming from the diode in the form of IR..


Otherwise, a decrease of 11% would mean, there is 13% room for improvement. The acrylic does not decrease power by 30% in comparison to the Meredith. The Meredith increases the power by 30% in comparison to the acrylic.


The Meredith would seem to be one hell of a lens. If this lens comes out similar, i'll be happy with it. Regardless of the actual power, it is still a lens designed for 405nm, so it should be good at it..

And if, for some strange reason, it should turn out not to be, nobody loses anything, except for me. So let's just treat this as an experiment for now..

I just received a response from Meredith Instruments about their glass lens.
They say, that the Meredith glass lens has an MgF2 AR coating optimized for 655nm.

The 405nm custom lens will also have an MgF2 AR coating, but optimized for 405nm. It also consists of a glass material with which this type of coating works particularly well (refractive index of 1.9.. regular glass =1.5).

And since it is very similar to Meredith in all aspects, only a bit larger (with a higher NA as well), there is no reason it should not work just as well.


I hope i receive another comparative measurement (AixiZ acrylic & Meredith) soon, and we should know more then.


I'd say it's looking pretty good for now.

Added. If the lens turns out well, we have 85 potential orders already. This could bring a considerable discount, compared to the first order..

If i knew how fast it would go, i would have waited for the samples, before posting the thread....
