Title:
MEDICAL-USE STEREOSCOPIC MICROSCOPE OPTICAL SYSTEM AND MEDICAL-USE OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/051969
Kind Code:
A1
Abstract:
The purpose of the present invention is to make a medical-use stereoscopic microscope optical system and a medical-use observation device small and light, and make images high-resolution. From the object side to the image side, an objective optical system and a plurality of image forming optical systems are disposed in that order, and the image forming optical systems include at least one aspherical surface. Due to this configuration, spherical aberration and curvature of field can be improved, and the system and device can be made small and light, and images can be made high-resolution.
