Understanding extended depth of field (EDOF)

Extended depth of field (EDOF) is a technique that helps you create images with a greater depth of field than ordinary microscope camera photos. 

What is depth of field?

Depth of field refers to the area in an image that appears sharp and in focus. Everything outside this zone will appear blurry.

Dino-Lite’s EDOF microscopes come in—they let you overcome this limitation and create an image that is completely in focus.

Whether you’re looking for greater understanding or to show off your specimens in all their glory, EDOF is the perfect solution.

How EDOF works

EDOF (also known as focus stacking) involves taking multiple photos at different focus levels and then digitally combining them into one image that’s sharp and clear from top to bottom. This process doesn’t compromise the quality of your image—it keeps all the fine details and high resolution intact. Plus, you can save, adjust and view your images easily with the included software.

Key features of EDOF

• Refocus mode: This handy feature lets you adjust the focal point anywhere within your image, so you can zoom to specific areas of interest with ease.
• DPQ depth acquisition: This tool measures the real-world depth differences in your specimen by analysing tiny changes in focus. It’s perfect for studying things like grooves, holes or any topographical details in your sample.
• One-touch autofocus: With just one tap, the camera will automatically adjust the focus to any part of the image within the focal range.

By using EDOF technology you can create incredibly detailed images, making it a valuable technique for any hobbyist or professional.
