The FM820Tis an upright fluorescence microscope with transmitted and reflected lighting, and a six-filter turret. The microscope is built around an infinity-corrected optical system with a 40X-1000X magnification range, and Koehler diascopic and episcopic illumination. The powerful 100W, wide-spectrum, mercury-vapor episcopic illuminator uses a rotary filter-selector which can house up to six fluorescence filter-blocks; already included are ultraviolet, violet, blue, and green excitation blocks. The sub-stage illuminator uses a 30W halogen lamp with field-lens and diaphragm for even, high-contrast lighting. The backwards, quintuple nosepiece holds five plan-achromatic objective lenses, including: 4X, 10X, 20X, 40X, and 100X (oil). The Siedentopf-design head features a 30° incline, and a 48-75mm interpupillary-adjustment range. A trinocular photo-port provides a stable, dedicated mount for an imaging system. The microscope uses coaxial coarse and fine focus-adjustment, as well as coaxial control over X and Y translation of the 7.2" x 5.6" stage. The digital imaging-system provides real-time 1080p video on an 11.6" LCD monitor at up to 60fps. Designed primarily for standalone use, the system's internal software is controlled via the included USB mouse. Photos and video can be captured, and stored on the built-in Secure Digital drive. The camera can also be connected to a Windows PC via USB, allowing for software-control with a range of editing and measuring tools.
