Abstract

Recently, more and more attention is paid to the multichannel optical system. They are often used in microscopy. Examples include metallographic microscopy, confocal microscopy, laser scanning microscopy, optical coherence tomography, and others. Usually, one channel of such systems is lighting, and the other is observation. Such systems usually do not pay attention to the uniformity of the divided light flux. Here it is important to illuminate the object and obtain an image, and if the illumination is insufficient, the luminous flux given by the source is increased. However, if both channels of the system are used for imaging (possibly with different characteristics), the uniformity of this splitting of the optical emission is an important part. Otherwise, we risk not getting the image we need in one of the channels.
