In this section, created with the book "Pencil of Rays", written by the former vice president of Nikon, Tadao Tsuruta, in mind, short essays on random topics concerning optics are provided.
  The section mainly consists of the "Misconceptions" series, which features common misconceptions regarding optics and the "New Optical Thoughts" series, which offers a consideration of optical technologies from new perspectives. Moreover, we are planning to add various topics such as the "Lyrical Understanding of Optics Theories" series, which presents easy understandings of difficult matters, and "Place With No Address", which features more recreational content. Please stay posted.
