New O-Like Blu-Ray Diode Housing with Glass Lens

[REVENGE]

Looks just like the housing for red diodes, except this one supposedly has an AR coated lens designed for 405nm light.

Cost is $50, and claimed power loss is 10-15%.

Are you referring to the price or the power loss?

;D ;D ;D that would be price ;D ;D ;D i'ma acrylic type of guy

10-15% power loss that's high and not worth it. Losses for an AR coated lens should run around < 0.5 % per lens surface

10% loss isn't bad at all...

With an acrylic non-coated lens we are losing like 40% of raw output power...

Those lenses you linked to have a 10% loss, at best. Higher at different wavelengths.

Here is the chart for the lenses you linked to at edmund

From what Igor told me its more like a 25% loss with an acrylic non-coated lens, give or take. So in reality its only about a 15% increase over plastic. For that money I'd stick with the 405-G-1 lens which will give you 28% increase over plastic.

;D So you have been paying attention...

You just may be a Blu-Ray Junkie after all! ;D

Re: New O-Like Blu-Ray Diode Housing with Glass Le

i'd be interested to see raw diode output vs output after jayrobs lens. I'd be willing to bet that you'll see around 10% loss. Jayrobs lens is great, I just think that the acrylics are a lot more lossy than we think, based on my own testing.

Re: New O-Like Blu-Ray Diode Housing with Glass Le

It would not surprise me to find even less than 10% loss. The lens data sheet claims 95% transmission.

The thing is, it's hard to get an accurate 'raw' reading. Because the light from the raw diode spreads out so fast...

price droped to $28 !

Re: New O-Like Blu-Ray Diode Housing with Glass Le

That price is a lot better - i might try one

Re: New O-Like Blu-Ray Diode Housing with Glass Le

I thought it was a 10-15% loss? You guys are confusing me :-?

Anyone buy one of these yet?
