In short, optical zoom allows to you bring the object close before you capture it. With digital zoom, your thermal uses a part of the image and sizes it later. That's why the risk of losing image quality is greater with digital zoom.
Navigating the thermal imaging landscape requires a keen understanding of the subtle but significant differences between optical zoom and digital zoom. In the realm of heat signatures, where precision is paramount, the choice between these two zoom mechanisms can profoundly impact the clarity and reliability of the captured thermal data.
On the other hand,digital zoomoperates by electronically enlarging the image. While this may seem like a convenient way to get closer to your goal, it comes with trade-offs. Digital zoom sacrifices image quality, often resulting in pixelation and loss of detail. In thermal vision, where detecting subtle temperature changes is critical, digital zoom can impact the ability to accurately interpret thermal signatures.
Our MH-thermal binoculars series have different resolution options: 384*288px and 640*512px sensor, higher resolution means clearer image, electronic zoom to 2X-4X is generally used in our MH thermal imaging series, imagine you are using our MH-6100B/MH-675 and other handheld thermal imaging equipment to measure a wide landscape. With optical zoom, you can zoom in on specific areas smoothly and clearly, capturing intricate thermal details that might otherwise go unnoticed. However, if you choose 2X/4X to enlarge the image, you can distinguish between different heat sources and see the target object you want to see.
