Large Aperture: The maximum aperture of the iris diaphragm can reach 23mm, and the light transmittance is stronger, which can make the observed object clearer and brighter in the dark without receiving external light sources. Compared with using a small hole to pass through the aperture, the convenience of use is greatly improved. Adjustable Aperture: The adjustable aperture is 1.5mm-23mm, and the dynamic adjustment range is wide. A single original can be used in multiple scenes, and it gets rid of the burden of needing multiple sets of apertures due to inappropriate apertures, making it more convenient to use. Durable: The outer casing of the microscope aperture is made of aluminum alloy material, which is stable in structure and durable, protects the internal structure from damage, and greatly improves the service life. Stability: The blade part of the iris adapter is made of stainless steel metal, which is resistant to wear and provides accurate measurement. The compact and practical design makes the diaphragm work more stably. Easy to Use: The aperture of this microscope can be changed through the handle, which is easy to operate, compact and easy to carry, and is a very practical laboratory accessory. Specification:
This microscope adjustable iris adapter is an indispensable component of laboratory microscope accessory. It is used to control the amount of light entering and change the brightness by adjusting the diameter of optical cable. The large aperture perfectly solves the problems such as the limitation of application range and the lack of brightness of light source.
