On the Drlava's prisms, what is the clear aperture? Is magnification adjustable; and if so what is the range?

Whatsa goez inta....vs. whatsa goez auta ??? OK....the goez auta is 2.4 W....What is the power going into the cube...for each 445 LD seperately....That... of course will give us a handle on PBS efficiency....and that can be compared to the JML PBS optic.

Beam Axiom #1 ~The Quantum well is DEEP ! Photons for ALL !!

Beam Axiom #2 ~Yes...As a matter of fact...I DO wear tinfoil on my head !!

Beam Axiom #3 ~Whe'n dout...Po ah Donk awn et !!
.
Beam Axiom #4 ~A Chicken in every Pot, and a Laser Lumia in every Livingroom !!
.
Beam Axiom #5 ~"Abstract Photonic Expressionism"....is "Abstractonimical" !!
.
Beam Axiom #6 ~ "A Posse ad Essea" ~ From being possible to being actual ...is the beam target !
Yeah neat little set up ... while you at it, maybe U can tell us what the drive current is @ those powers
also if the PBS doesn't have an AR coating ...aren't you worried about back reflection ?
Not a lot of cooling visible in those pics ... does the setup get hot ?.... or maybe you have a hidden TEC ...
@planters = DrLava uses cylindrical lenses not prisms @ a fixed ideal adjustment for best beam collimation.
Cheers

Catalanjo,
You're right of course. What I should have asked was what is the clear aperture for the anamorphic prisms that are being compared to the Drlava cylinders? Cylinder optics are easy to source if not so easy to set up. Sourcing prisms is more difficult.
Laserkits....thats the deal...your set up is very compact....great...I tend to over-engineer things...Ya !!! See the discussion in the 445 section !!! What is your beam geometry at 40 feet ???????????????? ( What does the spot on the wall look like ???? )
