ENX, thank you I have emailed mfgcn regarding line lenses they have.. it does not say if its one line or multiple..

Hello Trying to find a web shop that sells lenses that makes patterns (like the ones you get with cheap laser pointers with hearts etc) but I am not sure what to search for. Does anyone have a clue where I could get a hold of patterns like this? More specifically I am looking for a pattern with...

Yes after searching all morning it seems hard to find focal length under 2mm. But like you say, will just have to use more lenses. When browsing for lenses I find a bunch of different types, convex, bi-convex, concave, plano-concave.. All new to me, anything in particular in this case I should...

Bionic-Badger: What kind of lens are you thinking of? Cyparagon: Math is not my stronger side hehe Here is the specs for the laser: DPSS Laser,Green laser,Blue lasers,Red lasers form Lasever Says beam size is 2x4

Hm, okay, I though I saw some expanders that were defined by angle but I might have misunderstood it. Any clue to where I might find expanders that will do large expansions then?

Hello all! Quick question Does anyone know where I might find inexpensive beam expanders that would be able to generate a (ca) 45 degree angle? I have looked around for expanders and found a couple of places that sells rather cheap ones, but they usually do not expand to that extent. Cheers!

Wolfman29; Thanks :) Sure will! Cyparagon; Well, thats wrong... Both wavelengths are essential for the chlorophyll pigments, to use only blue would result in weak plants that would not be able to give flowers, fruits, seeds etc and would be very susceptible to stress in all forms. One can spend...

That might just be enough, thanks guys :)

I only own one laser at the moment and it does not seem like I can get the head of it without breaking the housing. Do you know about what angle of light it would give if I would take the lens off?

By the way... Does anyone know where I can get appropriate lenses for splitting up light from a laser from a little dot to a rather big one? Kind of like the heads you get with some hand held laser pointers but instead of “i love you” or a star I need just a big blob of light :P

It would work if the wavelength were a bit higher or lower, but it would not be optimal. To use for example 660 nm instead there would be about 10-15% less energy uptake in a plant. But I think I will have to settle for 660 for starters, and take it from there if I get any good results. In this...

Ahh, okay, I see.. I will keep what you have said in mind for future experimenting, but it is probably as you say not controlled enough. Need to invest in a spectrometer first in that case, and they do not come to cheap :) I have been in contact with many hundreds of companies that produce both...

Trevor; Hm, “overdriven” ? How do you mean? Line width as in the width of the light/spectrum produced? I have been experimenting some time now with LED for growing plants, and lately been wondering about lasers and if that might be a even better way to go since from what I have seen they have a...

Hello all Been looking around a bit for lasers that can produce 665nm, but like with LED it seems hard to find. Does anyone know where I might find lasers of that wavelength? Preferably >100mW. Thanks! /Erik
