Dichro Adjustment

[Banthai]

and dont forget this layout ( that im using )

its from a medialas projector, it was originaly posted by someone on PL and allows for easy near feild and far feild adjustment takes about 1 minute to align all beams perfectly ( easy peasy lemon squeazy )

i have shown the beam path in the bottom pic

all the best .... Karl

Hi Karl,

Mmmmm...I had not seen that geometry layout before.... I will strongly consider it for Projector#2... I guess it really depends if one's " Golden Eye " can pick up very small losses in mw output !!! HaHa With the extra bounce mirror in the beam path,...with a good mirror....1% loss...
In a RGBP of 500mw Red...5mw...and 200mw Blue...2mw.....Who could detect THAT !!

Upside; Extreme ease of nearfield alignment
No float table needed
Assists with Thermal managment issues

Downside; Very very minor mw loss
Extra cost of mirrors and mirror positioner

Thanx for pics !!!
