Smallest curvature radius in gradient index optics

Click For Summary
SUMMARY

The smallest radius of curvature achievable with current gradient index optics (GRIN) technology is approximately 5mm. This figure is determined by the minimum bend radius that graded index fibers can accommodate while maintaining functionality. To optimize performance, one must analyze the grading required to support specific mean bend radii and compare the maximum refractive index of various transparent materials.

Hello,

would someone know what is the smallest radius of curvature achievable with current gradient index optics (GRIN) technology?
I mean, how much could one "curve" a ray of light?

Many thanks! :smile:

That would be proportional to the smallest radius turn that a graded index fibre can still work at - and manufacturers tend to publish that figure.
I'm seeing figures of order 5mm.

You could figure out what the grading needs to be to support a particular mean bend radius and compare the maximum refractive index with transparent materials.
