Product Description

This cutting edge digital polarizing video microscope is ideal for jewelers, engineers, and scientists where close-up inspection and recording is essential. The video microscope sends live video instantly to laptops, desktops and tablets. The GT820 enables professionals to take microscopic measurements, share images, and keep digital records. The GT820 delivers these advanced capabilities, and much more, at a small size and truly economical cost.

Firefly’s GT820 delivers exactly 2 Megapixels of detail without using interpolation techniques. While such a large quantity of pixels may normally cause significant lags in capturing and displaying images, the GT820 is equipped with a cutting edge image processing engine which significantly eliminates visual lag, enabling an intuitive user experience.

Provides up to 235x native optical magnification and up to 700x digital magnification. To reduce glare in highly reflective objects, the GT620 is equipped with a polarizing filter that can be manually adjusted for 12 levels of polarization.

Highest quality ultra-bright LEDs are deployed with variable brightness control.

The GT820 is controlled directly with the FireflyPro professional image processing software which is bundled with the microscope. This state-of-the art software enables users to capture, measure, store and view images and videos in real time. Its intuitive interface empowers users to get right to work anytime and anywhere.
