Title:
LENS AND OPTICAL SYSTEM DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/201052
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a lens and an optical system device with which optical characteristics of a light source and an optical element can be measured in a simple configuration. A lens 1 has an optical axis, comprises an incident surface F and an emission surface B, and is formed such that the incident surface F and the emission surface B cause light entering the incident surface F at an illumination angle θ relative to the optical axis from a first position O to be emitted at an emission angle θ/m (m>1) relative to the optical axis from the emission surface B by means of refraction by the incident surface F and the emission surface B, and all of the apparent positions of the light emitted from the emission surface B begin at a second position P. In addition, an optical system device is formed of the lens 1 and a diffusion plate for diffusing the light emitted from the lens 1.
