A binocular head is a laboratory instrument used in microscopy to provide a binocular viewing experience for the user. It consists of two eyepieces and a viewing head that can be adjusted to different inter-pupillary distances for comfortable viewing. The binocular head typically has a diopter adjustment to correct for differences in the user’s eyesight, and may also have an adjustable inclination angle for greater comfort during use.

It is commonly used in research and clinical laboratories for a variety of applications, including histology, pathology, and microbiology. The binocular head provides a more ergonomic and comfortable viewing experience compared to traditional monocular observation heads and is especially useful for prolonged use or high-magnification microscopy.
