I Help Needed for Lens Selection for Fiber optics

AI Thread Summary
For collimating light from a fiber optic cable with a 30-degree half acceptance angle for fluorescence applications, selecting the appropriate lens is crucial. Both plano-convex and double-convex lenses can be effective, but aspheric lenses may provide better performance by reducing spherical aberrations. Users are encouraged to research lens options online for more insights. Gaining a foundational understanding of lens characteristics will facilitate more informed discussions and assistance. Proper lens selection will enhance the efficiency of the optical setup.

I am using a fiber optic cable through which led light propogate, fiber's half acceptance agle is 30 degree. I want to make the light (diverging)comes out of fiber into collimated beam and this collimated beam will pass through filters, sample and will be used for Fluoroscence application. hope you got the instrumentation set up. Which type of lens would best work for this application. Either Plano convex or Double convex , aspheric ! Please help me to find the best solution.
Thanks in advance

Thread 'The Physics of unloding sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'I need to simulate clothing meshes for hanging garments'

I don't need cloth simulation. I need to simulate clothing meshes. Made of triangles and I need an answer that someone with High School math can understand. I am actually using the time it takes for someone to answer to create a model with less geometry than the one I have been using. I want clothing that can be removed on a model that will be animated. I don't need stretching or wrinkles on my meshes, I just need gravity. I have an idea of how I could do it, but I don't know how to apply...
