who here has a laser using this method so i may see it in practice?

what size spot will that method produce at longer distances?

yes please, the more pictures the better! thank you very much!

i understand the many setups out there are very different and they will vary widely and that's just what i'm looking for, i'm interested in seeing how the very different setups stack up against each other at 200 feet because 200 feet will magnify the differences of all of the very different...

this is narrowed down... 1 - HH (hand held - in the title) 2 - beam profile (shape & size) 3 - at two hundred feet 4 - all the 1 watt or higher lasers 5 - of the many types and builds 6 - here at LPF and i'll add one more... 7 - from anyone who would like to share this information here...

i'm curious about the beam profile out at two hundred feet of all the 1 watt or higher lasers of the many types and builds that are here at LPF? thank you for your time...

they are listed under "Additional Custom Capabilities" in the catalog as they are not "asphere" lenses... wouldn't a lens like this eliminate the need of cylinder lens pair for fast axis correction after the beam is collimated by correcting the fast axis before collimating the beam?

are you talking about the "aspheric lens optimized to collimate Nichia’s blue laser diode" or the "Circulight Anamorphic Lens"? do you have a link?

at the cost of $155.00 US each it would have be the best lens on the planet by a large margin... LightPath makes another interesting lens that is placed right by the diode to slow the fast axis while allowing the slow axis to "catch up" to the fast axis before the beam is collimated? it's...

i sent them a email asking why their numbers don't add up and this was their response... for a full 17x the input beam could be no larger than 1.5mm?

here are the specs for the 352673A-00 lens... Aspheric Lens, EFL 4.01mm, NA 0.60, OD 6.33mm, MLBB-A coating Ravg<0.5% from 350-700nm, AOI=0 deg

the "BEW Series Beam Expanders" can be used with a "Beam Size of 4-10mm Diameter", that's the biggest i've seen...

has anyone seen these beam expanders before? the "BEW Series Beam Expanders" look very large? Beam Expander for green, blue, red DPSS laser.

during the chat i was told that Edmund does not make a lens that is equivalent to the LightPath 352673A lens in terms of performance when paired with the Nichia blue laser diodes...

Edmund Optics is a distributor of LightPath lenses... https://www.edmundoptics.com/products/lightpath-lenses/ yet they don't carry the 352673A lens and for some unknown reason they can't get them but she would not elaborate why that is?

no, not the 352673A, i live chatted with a sales rep and they said they don't carry the 352673A lens and they couldn't get them.

expensive, $145.00 US! for that amount money i would expect them to out preform a standard "G2" lens by a fair amount. :confused:

yes, could it be noticeably better with Nichia’s blue laser diodes than a standard "G2" lens since it is designed specifically for them?

here it is as a jpg uploaded here, the pdf which is also uploaded here is much better. this is the text... • Optimized for Nichia® blue laser • Compatible with other blue diode lasers • Aspheric molded glass lens • Diffraction limited performance • Compact, single lens design • Short...

has anyone seen this make of lens before? it's a aspheric lens that has been optimized to collimate Nichia’s blue laser diodes.
