The T720-TP is a feature-rich microscope with a turnkey 9.7” touchscreen tablet-based imaging system. Designed for professional biological applications and advanced education, the microscope offers high-end features. Its infinity-corrected optical system ensures reliable, low-distortion magnification, with plan-achromatic corrections for accurate colors, excellent field flatness and edge-to-edge sharpness. The Koehler-design LED illumination system provides bright, evenly-distributed light for maximum contrast and definition. Key Features include... 40X - 2500X achromatically-corrected magnification 10X & 25X eyepieces included 9.7" Touchscreen Tablet included Integrated with 5MP Camera for video and photo captures Fixed 23mm tube Objective Parfocal Distance: 45mm Stage Dimensions: 216mm x 50mm / 8.5" x 5.9" LED Illumination Includes AC Adapter Objective Lenses included... 4X, 10X, 40X, 100X Tablet Specifications include... Android OS Dual-core 1.5GHz 1GB DDR3 Memory 2GB Internal Storage MicroSD External Storage 9.7" Color Touch Screen 1024 x 768 Resolution 360° Display Mount Rotation 5MB CMOS Camera The trinocular head accommodates simultaneous viewing through both eyepieces and the top-mounted photo port. The binocular viewing tubes use Siedentopf adjustment to easily fit any user. Focusable eyepieces are used to compensate for users with astigmatism or asymmetrical sight. The included 9.7” tablet has an integrated 5MP C-mount camera which attaches to the head’s photo port. Use the touchscreen interface to capture photos and videos while you monitor specimen activity on-screen. The tablet is wi-fi enabled, and supports file-sharing through MicroSD cards or compatible USB drives.The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, soil, and bacteria. 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 large 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. 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.Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The LED light-source ensures cool, energy-efficient illumination with low heat for live specimens. The bright light-source is daylight-balanced to produce natural colors for imaging. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm 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 illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.
