When we observe objects under a microscope, we often observe the following characteristics:

1. When the distance between objects increases, the corresponding observation magnification decreases, the visible range of observation increases, and the depth of field of the object that can be seen clearly increases;

2. When the distance between objects decreases, the corresponding observation magnification will increase, the visible range will decrease, and the depth of field range that can see objects clearly will decrease;

So, in order to obtain clear microscope observation images, is there any way to achieve the requirement of using larger magnifications while also obtaining a larger object depth range?

Dino Lite handheld digital microscope breaks through conventional observation methods and meets customers' demands for this feature.

In DinoCapture 2.0 software, emphasis is placed on developingEDOF (Extended Depth of Field) function, which is an image capture mode. It integrates multiple images with different focal points into one image with multiple focal points to increase the depth of observation.

As shown in the above figure, the image on the right is taken without using the extended depth of field function. When we focus on the top layer, the images at different heights in the lower layers are blurred. But after using EDOF (Extended Depth of Field) technology, as shown on the left, we will get an image with clear layers from high to low.

Does all Dino Lite handheld digital microscopes have this function? Actually, it's not. Only certain specific models have this feature. Below are the product models with this feature for your reference.

AM4815T/AM4815ZT/AM4815ZTL (1.3 million pixels, USB 2.0 connection)

AF4915ZT/AF4915ZTL (1.3 million pixels, USB 2.0 and wireless WIFI connection)

AM7915MZT/AM7915MZTL (5-megapixel, USB 2.0 connection)

AM73915MZT/AM73915MZTL (5-megapixel, USB 3.0 connection)

The above series of products all have EDOF depth of field extension function.
