The FM820T is 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 wide magnification range and Koehler diascopic and episcopic illumination. The powerful 100W, wide-spectrum, mercury-vapor episcopic illuminator uses a rotary filter selector that can house up to six fluorescence filter blocks, including ultraviolet, violet, blue, and green excitation blocks. The sub-stage illuminator uses a 30W halogen lamp with a field lens and diaphragm for even, high-contrast lighting.
Viewing Head
The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field of view to see more specimens at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to align the oculars without readjusting focus properly. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses and is height-adjustable to match focus with the eyepieces. The port is compatible with YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens - ideal for 1" format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.
Optics
The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, ensuring highly precise images. The quintuple objective turret provides instant access to 5 magnification levels. This allows you to efficiently move through magnifications from 40X to 1000X. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are achromatically corrected to improve resolution and color accuracy, with planatic flat-field correction to provide edge-to-edge sharpness.
The Stage
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides, with a large translation range for viewing larger samples. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. Symmetrical focus controls are coaxially mounted for fast, intuitive focusing. A height limit can be set to prevent contact damage, as well as presetting optimal focus distance.
Koehler Transmitted Illumination
Built on Koehler illumination principles, the sub-stage lighting provides evenly distributed light for optimal contrast. The rear-mounted 30W halogen light source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with an NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth of field. The condenser holder uses rack-and-pinion height adjustment for precision control and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light spread, optimizing contrast and definition in specimen features.
Epi-fluorescence Illumination
The epi-fluorescence illumination system adds incredible versatility to the microscope. The ability to isolate fluorescing compounds allows you to target individual proteins and other nuances. This microscope is equipped with a six-position filter turret for easy transitions. Four filter blocks are already mounted (ultraviolet, violet, blue, and green) for popular labeling agents and natural fluorophores. The illuminator uses a high-power mercury arc lamp for wide-spectrum excitation.
Fluorescence
Mercury HBO lamps produce a wide spectrum of wavelengths, including ultraviolet. While this fluorescent light-source can excite fluorophores throughout its entire spectrum, there are peak wavelengths with optimal output.
Digital Imaging
The ultra-sensitive 2.3MP digital camera uses a cutting-edge global-shutter CMOS sensor which provides better motion-rendering, eliminating rolling-shutter artifacts. The design based partly on CCD architecture provides extremely high sensitivity, ideal for fluorescence microscopy and other low-light applications. In brightfield applications, the camera can record up to 30fps. The camera captures still images and video and allows you to view a live stream on your PC. With software 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.
