XSP-200E Binocular microscope with Iris Diaphragm Filter

A binocular microscope with an iris diaphragm filter is a type of microscope that provides enhanced control over the amount and direction of light passing through the specimen. It consists of a binocular head that allows for comfortable and ergonomic viewing, along with an iris diaphragm filter that is placed near the light source. The iris diaphragm filter is a circular mechanism with adjustable blades that can be opened or closed to regulate the intensity of light entering the microscope. It helps in controlling the brightness and contrast of the specimen, improving the visibility and clarity of the image. The iris diaphragm filter can be particularly useful when observing transparent or translucent specimens, as it allows for better illumination and reduction of glare.
