I got a standard unit.

Hello I got the projector. Learnt a lot while trying to measure the beam length at full power by projecting horizontally - 10 km(white) Yes- the white beam(28W) is more visible than The 10 W green as the white beam length was visible for 2 more Kms. Oh yeah - world is round and the beam...

Thanks for the reply. Here is a link I found on Luxor with costing https://gamboool.com/luxor-light-can-you-see-the-luxor-sky-beam-from-space-and-what-is-the-light-bill-on-that-thing I read somewhere Luxor light is an FAA designated markers for pilots to confirm they 're over L.A. (What...

Yes. Since my projection angle is vertically up, hence the high power.

Thanks a lot for your inputs My laser projector is arriving in a few days. Will keep you posted on performance /visibility/distance etc Pranam

Yes. The white will be brighter.. But in terms of visibility how to compare white (composite of all wavelengths) and a 520 nm beam? 2 corrections in my data inputs : 1. Visibility needed is only 15 miles (aerial distance ) - my bad. 2. The angle at which the laser will be projecting is a...

The visibility needed is only 19 miles (30km) Back to my original question- would a 10 w green opsl be more visible than a 29 W white ? Beam diameter is 5.5 x 6mm at source and beam divergence is 1 mrad (a full angle)

http://www.kguttag.com/2011/12/16/diode-green-lasers-part-1-wavelength-and-efficiency/ I referred the above link for checking the lux level of laser beam at various distances (attachment in first query) But unsure if these values hold true for Green- OPSL + Blue & Red - DPSS Will the beam be...

Sorry about the lack of detailed specs in my query.. The guaranteed power is 29 W Red - 637nm - 8000mW Green - 520 nm - 10000 mW Blue - 460+445nm -11000 mW (not sure of the power split up between the two blues) The purpose of this project is 1. Create a "Pillar of Light" 2. And to provide a...

Any one out here in LPF who can help me out?

I have compared the beam diameters of two high range lasers(see pic) Assuming zero lumen drop , see the lux levels at different distances. Clearly , the LD - low divergence of .5 mrad is having twice the range . This exercise was an attempt to find our the visibility of white beam. Assuming...

Hello all, I am new to the laser. I am in the verge of ordering a laser projector. Basically an electrical engineer, graduated in 2012. Currently volunteering for a Non profit organization Need your inputs on laser beam Vs visibility vs power
