Wide Angle Board Lenses or Fisheye Board Lenses
 
 
Wide angle board lens is usually called Fisheye Lens, because of its very short focal length and wide angle of field of view, usually wider than 100° and focal length less than 2.8mm. It is different from digital camera, in which area, the angel of view may reach 180°. This series of lenses can help the camera to catch a wider enough area in a shorter distance, such as to monitor a whole room while mounted in indoor place, or some mini device but requiring larger view area.
All Lenses are made of aluminum mechanical parts and optical glass elments.
 
Different types of filters can be optional for special application, such as IR cutoff filters for visible light viewing, IR Longpass filters for NIR light viewing.
