Aspheric Mag, one more!

As we all know, reasonably priced 52mm aspheric lenses are hard to find. I didn't want to pay 50 euros for a coated aspheric lens and I solved the problem my way. I bought a 55mm F38.5mm lens from Surplusshed (PL1014) and I made a bezel to house the lens. The light engine is a Cree XR-E Q5 driven by GD1500.

SSC P4 modded Gladius on left. The lights are 190cm off the wall.
1/1600s F3.5

The Gladius seems really lacking when compared with the aspherical mod.

:goodjob:

Nice light and nice bezel construction!

Could you post some more pics showing the bezel better? I would really like to see what you did. Can you focus the diode on objects really far away? I rigged mine up to focus at 10ft to about 1000!
Looks great!
Edit*** I just looked again and now the bezel picture loaded. Nevermind!

I wonder if the 55mm has more throw and focuses better than the 52mm, if so, have you tought of making and selling some bezels?

Ledean reported that his 52mm aspherics threw much better than the 50mm ones.

I somehow predicted that question

. Sorry, I have no time to make more bezels. I made the bezel at the school with manual machines.

I have no lux meter to measure the throw. Maybe I'll get somewhere outside the city during christmas holiday so I could take long distance beamshots.

Two beamshots

Distance: 95 meters

Distance: 35 meters

Try finding a 52mm somewhere for less than $25.

KD has them but they aren't selling them yet. Price is set at $15 shipped.

I changed the led to a blue cree and I wired two KD SKU2958 drivers in parallel to power it.
