This is a feature-packed, economical metallurgical microscope with an upright design, and both trasmitted and incident illumination. The episcopic illuminator includes removable polarizer and analyzer, as well as adjustable field and aperture diaphragms. The plan-achromatic optical system offers sharp, flat-field images with excellent color-correction. With 10X and 16X eyepieces, twelve magnification settings are provided: six metallurgical (50X, 80X, 100X, 160X, 500X & 800X), and six bright-field (40X, 64X, 100X, 160X, 400X & 640X). The Siedentopf head with dual diopters and high-eyepoint eyepieces provides a comfortable and adjustable viewing platform. There is also a dedicated photo port for simultaneous viewing and imaging. The 18MP digital camera captures still images and video, and allows you to view a live stream on your PC. With software available for Windows, Mac, and Linux, it's a multi-platform imaging solution. The included Windows software offers image-development and measurement tools, as well as advanced compositing features such as image-stitching and extended-depth-of-focus. Independent preview and capture resolutions allow you to view high-speed video while capturing high-definition images. For Mac and Linux, there is a lite version with limited processing features.
