摘要：
We present a new liquid crystal-based device for correction of spherical aberration, which is commonly observed in microscopy and related methods. The device is significantly larger than previous direct laser written aberration correctors, measuring 1 mm across. The device operates in transmission mode for easy integration into the optical path and is capable of continuous greyscale tuning of up to a total amplitude of 2 pi rad. This device could present a cost effective and simpler to use alternative to traditional wavefront modulation technologies used in adaptive optics.
