Object Examination in Transmitted Light

Camera images taken in transmitted light are characterized by their high level of contrast and are ideal for determining objects’ outer dimensions and contours. Transmitted light applications are normally recorded with black-and-white cameras, that's why the back lights have red color. But other light colors such as white, blue, green and IR are also possible upon request. Back lights have an M12 plug, are directly connected to a 24 V power supply and do not require a separate controller. Switching mode is also possible.

Back lights from Polytec come in 15 standard sizes with dimensions ranging from 25 x 102 mm to 152 x 305 mm. Due to the modular structure (25 x 51 mm), we are more than happy to create individual solutions especially for your application too.
