Title:
OPTICAL SCANNING DEVICE AND ENDOSCOPE DEVICE
Document Type and Number:
Japanese Patent JP2016161595
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To control a position of a convergence spot along an optical axis direction of emitting light from an objective lens in an optical scanning device and endoscope device.SOLUTION: A first lens 400 is arranged on an opposite side of a second movable reflection section 104 via a third stationary reflection section 206 in a plane view, and further, the first lens 400 is configured to converge incident light reflected by the third stationary reflection section 206. A second lens 300 is arranged between the third stationary reflection section 206 and the first lens 400 in the plane view, and further, the incident light reflected by the third stationary reflection section 206 is incident into the second lens 300. Furthermore, the second lens 300 is movable along an optical axis direction of the incident light reflected by the third stationary reflection section 206.SELECTED DRAWING: Figure 1
