We present a compound adaptive objective lens in which a water-filled membrane lens is inserted into a front group (one lens) and a back group (two lenses). This adaptive objective lens works in the ultrabroad near infrared waveband (760nm ∼ 920nm) with the volume scan of > 1mm3 and the resolution of 2.8 μm (calculated at the wavelength of 840 nm). The focal range is 19.5mm ∼ 20.5mm and the numerical number is 0.196. The size of the adaptive lens is 10mm (diameter) × 17mm (length). This kind of lens can be widely used in three-dimensional (3D) volume biomedical imaging instruments, such as confocal microscope, optical coherence tomography (OCT), two photon microscope, etc.
