Focus-position compensator |
摘要 |
The present invention is directed towards a focus-position compensator for reducing focus variations on a microlens array. The focus-position compensator comprises a plurality of tiles that are affixed to a structure disposed between the lenslets of the microlens array and the target of the collimated light from the lenslets. Each tile refractive index and tile thickness is chosen to obtain a tile focus-position correction that will apply to a region of the microlens array.
