Latab Line light illumination is typically used in combination with line scan cameras as a reflecting or transmitting light source. An important feature of line lights is the homogeneous light distribution, which can be even further increased by using diffusers. Line lighting itself is also applicable for the illumination of surfaces (two lines in parallel or four lines in a square formation are available). The standard lengths range from 38 mm to 542 mm, which also allows easily lengths up to 3 m.
