Note This product's magnification can be changed continuously from 25? to 175? without changing the lens. After using a low magnification to quickly find the location that you want to observe, you can then increase the magnification. This product is standard-equipped with 2 types of illumination heads : a contact type and a non-contact type. The non-contact type has an observation distance of 25.5 mm, which gives it excellent operational efficiency. A great number of illumination adapters can be attached to this product, which makes it possible for this product to adapt to a wide variety of observation uses.
