Another project red?

[andy_con]

the two lens/optics i just posted above are used to combine multiple beams into a single usable beams, the two optics together cost £60, which isnt to bad.

but for mech proposal there is a better way of doing things when it comes to combining lots of beams.

Andy, do you have any pictures (or better yet, real-world measurements before and after) of these two lenses? I don't remember you having these installed in your projector, but I may have missed it. Would be very interested in hearing about any personal experiences with these two lenses.

And that would be.?.

I have done work for a certain forum member who can vouch for my quality. Although he won't be able to speak for about a week because I just shipped him the parts today.

With good lensed there is no need to shrink the beams together, the 650mW reds I resell are made with 4 diodes and have a beam of 2,5 x 2,5mm x 0,7mrad.

It makes no sense to use a telescope to reduce the beam size of crappy lenses.Start at the beginning, and get a small as possible beam to start with.

Not to derail the thread again, but i would like to apologize to mecheng3 firstly and most profusely for my negative nilley post of "you can lead them to water". Secondly to anyone who may have been exposed to my venom spewed imparting unnecessary drama. Thirdly to andycon for any disrespect which I may have imparted. I was having a very bad day and today is not shaping up any better, thats no excuse only an explanation. No need to acknowledge this post (and continue dis rail), but please excuse my ignorance..if i could delete it, I would.... carry on...

Misterwilling - where are you located? If Daedal's new mirror mount idea pans out, it might be cool to get a few machined to see how they work in real life...

Adam

If this does work, and if we will be machining the hex but, I see the benefit of making the sides with varying angles (one at vertical 45 degrees, one at a horizontal 45 degrees). Since the nut can be flipped, only one angle of each needs to be made.

Also, as opposed to using regular screws, we could use headless screws with a flathead slot at the top. The bottom screws can be flipped around so the base angle can be adjusted from the top, and so can everything else.

I would be interested in this as well...

if you come to a future uk meet you are likely to see these lens on a new projector.

8 diodes (in 2 rows of 4) about a 3mm/1mR beam
15 diodes (in 3 rows of 5) about a 4.5mm/1mR beam
24 diodes (in 4 rows of 6) about a 6mm/1.2mR beam

thats using roithner GS-7020H lens

agreed for 4 diodes no additional lens are needed

The lenses I bought were single element high transmission AR coated with a loss of less then .3% . So I was only thinking about power output when I bought them and unfortunately I forget about beam diameter. Forgive me as I am just getting out of the laser pointer world and into scanners.
What lenses do you recommend? And how much do they cost per lens. I have the equipment to make my own lens assemblies if I can get them bare for a cheaper price. I know I have heard people using Lens27.

Offtopic: @ mccarrot : Did you ever have time to look for those aluminized scanner mirrors?

well the 7020H is only like £3 per lens, it only has a plastic lens, but gives far better output power than a standard aixiz lens and aixiz glass lens. it also produces a small beam than both aixiz.

the lens27 is about £20 per lens, but it is amazing and the results are fantastic.

Andy, would you happen to have one of the lens27 collimators? I'm assuming you have access to the 7020H lens, but if you could compare the two, against the AixiZ lenses, we would all be very greatful. £3 per lens is a great price if the lens truly proves better than the AixiZ glass lens. I believe the AixiZ glass lens is a multi-element assembly.

Thanx;
