Laserwave Upgrade Dichroic asking for test

[bridge]

Thanks, Ian, good job.
Your chart make things more clearly, .
I also find there is little different when different people test, below is Ian and Maurice test together.
the same reflect red pass dichroic.
Maurice(Mccarrot) test result is:
red reflection, 97.5%
green transmission,96.3%
Ian(Doc) test result is:
Red reflection, 99%(look from the chart, maybe Doc would like give us exactly data)
Green transmission, 96%(look from the chart, maybe Doc would like give us exactly data)
Reflect blue pass green and red
Maurice test result is:
blue reflection, >99%
green transmission, 96.4%
red transmission,97.1%
Ian test result is:
Blue reflection,>98.5%
Green transmission,>94%(look from the chart)
Red transmission,>94%(look from the chart)
Best regards!

hi doc did you not try pass blue on the reflect red dichro ??
thanks

Hi Chris, as reflect red pass green and blue dichroic, most are using it to combine green and red lasers, so Doc thought, it is useless to test refelct red pass green dichroic's transmission rate of blue.

every person here has other measuring results?!?

I know, this is a big problem of the Chinese manufacturers... one part is good one is very good and a other is bad... and this in the same batch.... I don't know why, but it was all the time so.

exactly the same with the Edmund dichros! I know them very good and they are manufactured in china too! I had edmund Dichros with very good efficiencies >98% ... but a few weeks later I have ordered the same dichros from Edmund end they had only 90% efficiency.... so the quality of them is bad!

that's the reason why we have looked for a manufacturer which makes all dichros in the same very high quality with 98, or 99 or more % efficience. and this not only for a sample-piece.

why is it useless to test blue transmisson, ??
i wanted to know how much blue i would lose through the dichro, my blue laser is second in the line so it has to pass through the reflect red dichro
thanks

Hi Chris,
Maybe you can reference Mccarrot's test.
his result is:
red dichroic(reflect red pass green and blue)
red reflection, 97.5%
green transmission,96.3%
blue transmission,97.4%
you also can find this result in his threads.
Best regards!

Hi Vakuum,
Welcome join this threads.
Don't worry, there are 5 ruputation members test our dichroic here.other result will coming soon.
Maccrrot, had test result
Doc, had test result
Loopee, had test result
Allthatwhatis, I thought soon will had result
300EVIL, I thought soon will be had result too.
Thanks for your words, Laser-wave had been there long time, members here know Laser-wave and Bridge exactly, we don't want to sell only 1pcs products, make only 1 customer happy, Laser-wave always want to make all of our customers happy.in every laser-wave men's heart, customer satisfy is our most pleasure things.
Best regards!

Chris, chill man, I will test tonight and post the result

Vakuum, maybe the difference is due to the fact that I am using 650nm red and Maurice is using 660nm?

Bridge, I will add the exact figures when I get home from work.

Further data omitted from initial test; red dichro, pass blue performance:

Old Laserwave = 91%

New Laserwave = 96%

Series data added to chart for clarity:

[mccarrot]

Red = 400mW 658nm dual diode
Blue = 130mw 473nm
Green = 250mW 532nm

I REALLY HATE THE NEW FORUM LAYOUT HOW CAN YOU SHOW THE ATTACHMENT PICTURE NORMAL AND NOT AS ATTACHMENT???
