Author Correction: Super-achromatic monolithic microprobe for ultrahigh-resolution endoscopic optical coherence tomography at 800 nm

Abstract

The original version of this Article contained an error in the third sentence of the ‘Animal studies’ section of the Methods, which incorrectly read ‘The sheep anesthesia was initiated with ketamine (25 mg kg−1) and then maintained by continuous intravascular (IV) infusion of propofol (800 mg kg−1 h−1) during imaging.’ The correct version states ‘800 µg kg−1 h−1’ in place of ‘800 mg kg−1 h−1’. This has been corrected in both the PDF and HTML versions of the article.
