Linear Light

Linear Lights are lighting components that illuminate line illumination. The linear lights consist of quartz rod and aluminum casing. Its excellent lighting characteristics, including its high uniformity of intensity, make it one of the most suitable lighting systems for scanner and inspection instruments that are used with CCDs or line sensors. Halogen and metal halide lamps as well as LED fiber light guides can be used as a light source. Linear Light also has a low thermal transmission coefficient. Furthermore, as the rod and light source sections are separated from each other, it is easy to maintain Linear Light and to replace lamp. Effective light emission lengths ranging from 100 mm to 2,700 mm are available.

  • The directivity is high. Thus, irradiation light near parallel beam is achieved, makes it possible to illuminate consistent intensity, with small uneven intensity.
  • Irradiation width is 2~10mm(5mm is standard.). It is possible to design freely from 100mm to 2700mm in effective radiation length.
  • Heat emission from the irradiation surface is small. Thus, objects are not chosen.
  • Because transmitting light and light source part are separated, lamp exchange is easy for maintenances.
