Abstract
A near infrared illuminator can facilitate the adjustment of an optical axis thereof with favorable accuracy. The near infrared illuminator can include: a light source configured to emit near infrared rays; and a projector lens configured to project the near infrared rays emitted from the light source forward to form a predetermined light distribution pattern in front thereof. The projector lens can include a light distribution control section configured to project part of the near infrared rays emitted from the light source forward to form the predetermined light distribution pattern, and a marker forming section configured to project part of the near infrared rays emitted from the light source forward to form an alignment marker for positioning the light distribution pattern at a predetermined position beside the light distribution pattern.
