  • 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.
