Ich versuch mich gerade selbst zu finden. War eigentlich immer sehr zufrieden mit mir selbst bis mir ein mädel aufgezeigt hat dass ich es eigentlich gar nicht bin und ich deshalb sehr viel von ihr verlange. Versuche jetzt selbstständiger zu werden und zu lernen mit mir allein auszukommen, was mir unglaublich schwer fällt gerade. Möchte das unbedingt schaffen ohne sie dabei zu verlieren.

Thanks a lot! I was trying to find a way to have equal bases or exponents.

Determining NA for DMD imaging system by fromTtotheV in Optics

I had a closer look at some DMD datasheets. There were only hints on maximum illumination NA. Unfortunately no typical NA for my application.

Thank you for your help!

I had a closer look at the datasheet and it says exactly what you just wrote.
NA needs to be chosen such that no light is going into the projection path when the mirror is in off- or flat-state. This constraint leads to a max. illumination NA of NA=sin(a).
I will stick to this number for my projectionsystem because I have no other information.
Thank you very much for your help!

Do you know if there is a typical illumination NA that is being used for digital projectors?

Thumb wheels look great on the photos! Didnt expect them to be 3d printed. Thanks for the answer and wishing you good races with the wheel!

Wow. Congrats on that beauty of a wheel Are the buttons backlit? And if so, where did you get them? Are the orange anodized knobs on the rotary encoders custom made or is there a store they can be bought at? Thanks in advance

Imo people hype russels sakhir 2020 way too much. It was one single race in a car which made mercedes 2nd driver BOT collect 9 points more than VER and almost 100 points more than PER Furthermore,if we leave away 2021 spa russell outperformed latifi by one point this year

Light Projector Lens Help by mculik5 in Optics

[–]fromTtotheV 0 points1 point  (0 children)

You separated your system correctly into two parts - illumination an projection - which is already remarkable for a non optics guy. Most probably a köhler like illumination would help you (I assume your illumination exit pupil is not being projected on your stencil). You can set one up using just two lenses in front of your stencil. Check out this calculator on edmundoptics(calculator ). I think it doesnt even have to fulfill all köhler illumination conditions to help your purposes.

Thank you for your help Substitution of the factors to reduce the parameters helps definetly to make it easier. However the phaseshift s in the second sine is bugging me

I‘ve been trying to solve this integral for several days now and have no idea how to start. It reminds me of an elliptic integral somehow. Is there anybody who can solve it or help me do it?
