Abstract: The present invention provides an optical filter for its use. In the present invention, it is possible to provide an optical filter that effectively blocks ultraviolet ray and infrared ray and exhibits high transmittance in visible light. Furthermore, it is possible to provide an optical filter where the transmission characteristics are stably maintained even when an incident angle is changed. Moreover, it is possible to provide an optical filter that does not exhibit problems such as ripple or petal flare.

Abstract: The present invention provides an optical filter having a narrow bandpass, high transmittance in the bandpass, low transmittance outside the bandpass, little change in optical properties even when the incident angle of light changes and thus, being advantageous in terms of yield and cost per hour. In addition, the present invention may provide a LiDAR system including the optical filter and an application of the optical filter and the LiDAR system.
