Title:
VISIBLE LIGHT AND NEAR INFRARED LIGHT IMAGING SYSTEM
Document Type and Number:
Japanese Patent JP2021036257
Kind Code:
A
Abstract:
To provide an imaging system that allows imaging of visible light and near infrared light without complicating and increasing the size of the system.SOLUTION: An imaging system has a reattachment that branches subject light incident on a replaceable imaging lens into visible light and near infrared light with a reflection member, and visible light imaging means and near infrared light imaging means that perform imaging of the visible light and the near infrared light, respectively, which are branched by the reattachment. The imaging lens has focusing means, performs focusing of any one of the visible light imaging means and the near infrared light imaging means, and performs, with different focusing means, focusing of one imaging means whose focusing is not performed by the imaging lens. An optical member arranged inside the reattachment is the reflection member alone and appropriately satisfies a conditional expression related to a flange back.SELECTED DRAWING: Figure 1
