Re: FS: Meredith Glass Lenses Fit For AixiZ! +20%

Thanks for posting back with your measurements! :)

Wow! That's close to a 25% increase!

I must mention that this result is probably not the norm. I have always measured 20% increase in power for a Meredith glass lens vs AixiZ acrylic (back opened) using red long open cans...

I am happy to see that you have such good results, but I just had to mention that so that people would not expect more than 20%.

Thanks again Barry!

Hey Jayrob!

Got the lens in the mail today, screwed it in immediately. Fits perfectly. I got no LPM (yet) so I can't measure how much of an increase I've gotten. But it seems to cause a whole lot more smoke at least :D

Aixiz Acrylic- 233mW
Aixiz Glass- 240mW
Meredith glass- 290mW

A 57mW increase, very nice
Wow, 25%, very nice, indeed :D

I'm shocked though to find out that there's only a 3% increase from acrylic to glass... :eek:




p.s. I reported the auto-spam post above (Gabriboy). First time I notice it managing to "infiltrate" a thread... this sucks big-time... :(

An alternative is the AR-coated acrylic lens from Virtualvillage, which is available from $6 up (depending on where you order) and which gives a 10% improvement - only half of the Meredith lens, but at a bargain cost.

Jay, thanks a lot for wonderful packing, and quick shipment. Everything came in order A+

I had time today to test and i am happy to find that there is about 16% increase over standard aixiz glass lens. Beam is slightly tighter than aixiz lenses, but not as tight as with your 405-G-1 mod. It is after all the best lens for our diodes so far, and its a pleasure to have it.

I tried to take some shots of beams with 4 different lenses i have handy, and show beam diameter comparison. It is easier to tell the difference in real life as opposed to the photos though. In other words, difference is greater and more exciting in reality!!

I will update my thread in review section with bit more info.

best regards, great job !!

Thanks for posting with great detail and pictures too Miloš!:kewlpics:

Your reading of 16% more power vs AixiZ glass is exactly in line with the measurements that I have taken and listed above. :rolleyes:

I got a 4 to 5% difference with AixiZ glass vs AixiZ acrylic (back opened) for red. And a 20% increase for Meredith glass vs AixiZ acrylic (back opened). There's your 16%! ;)

Jayrob Strikes Again!

Got my lenses shipped to me at work. Popped in the Meredith red at lunch and impressed a few engineers (also had my Kryton blu-ray with the 405-G-1). Went home and immediately busted out the Kenometer.

Original AixiZ glass lens: 261mW
Jayrob Meredith glass lens: 311mW

As an added bonus the beam is tighter at aperture with the Jayrob Meredith. The 50mW gain represents a 19.2% increase in power.

That's right, my humble Kryton Smooth is now an official 300mW monster. I cannot wait for the sun to set to check out the beam in the Florida humidity.

I wonder if these fit the Dilda...

Bottom line - if you like red photons then you'll definitely need this lens. I've never seen so many from a single source!

Hey Jay, I just finished the LPC and have the Meredith module installed. I'm getting some weird effect around the focused dot. It looks like it is going through a diffraction grating. I'll post a picture in a few minutes. I don't think it is your lens and I can't wait to give you some numbers when my LPM arrives.

Thanks Jay, you Da Man

gecko991, I got your PayPal, thanks! I will ship today. (Wednesday)

sbdwag, same goes for yours...

Please post back with your results! :)






k1kb0t, that sounds strange... I clean and inspect the lenses before I assemble them, so I don't think it is the lens. But the Meredith glass lenses do have some 'side splash' similar the the 405-G-1 glass lenses.
