Thanks for the reply! There is no field aperture positioned between lenses 2 and 3, the diffraction orders of the DMD are recombined with the 4f-setup.
Hi! I'd like to calculate the diffraction-limited resolution for the following optical setup:
Source: multimode fiber end, NA = 0.2 --> smallest NA, likely limiting?
Wavelength: 1500 nm
Lens 1 & 2: f = 50 mm & d = 25 mm
Lens 3: f = 30 mm & d = 12.5 mm
Is it correct to assume that the...
Thanks a lot for your replies. I will try to recombine higher diffraction orders too.
Thanks a lot for the input and the simulation results! :smile:
My idea was to collimate the light before the DMD and to scale the projection of the individual mirrors (10.8 x 10.8 µm) down a bit using the...
Hi everyone,
I have a question regarding the design of an optical setup based on a Digital Micromirror Device (DMD) and would love to hear your thoughts. 😊
I am using a multimode fiber-coupled laser (fiber core diameter = 50 µm) to illuminate my DMD. The setup is intended for an optical test...
