Axetris' Shack-Hartmann lens arrays are the heart of Shack-Hartmann wavefront-sensors. These microlens arrays are available in fused silica and in a variety of focal lengths. • Diffraction ...

... in a square grid with a lens pitch of 150 µm or 300 µm. The arrays with a pitch of 150 µm have round lenslets. The arrays with a pitch of 300 µm have square lensets, allowing for a fill ...
