Ken-a-Vision designed the 110VAC US version of their binocular-head configured TU-19644C Dual Purpose Digital Monocular Microscope from the ground up to optimize the digital learning experience by providing plug-and-play compatibility with Windows, Mac and Linux operating systems, as well as supporting interactive white boards and simultaneous multi-camera classroom setups. Utilizing an angled binocular head preserves stereoscopic vision allowing for a more comfortable viewing experience with a true depth of field that monocular heads are unable to provide.
A 5.0MP digital camera is built into the head and is co-witnessed with the eyepieces so what is seen in the eyepieces is exactly what the camera sees. The camera captures video and still-images in up to 2595x1944 resolution and outputs in 1080p at 30fps. In addition to the optical magnifications provided by the eyepiece and objectives, there is an option for up to 16x digital zoom. An included 6' (1.8m) USB cord supplies power to the camera and sends data to the computer.
The optical system features two 10x eyepieces - one with an integrated pointer - set in a 30°-angled monocular head, and a four-objective 360° rotating turret with click-stop positions at each lens. Four objectives from 2x to 40x produce a broad magnification range of 20x to 400x making this microscope a versatile observation tool. Its achromatic glass objectives are designed to correct for chromatic and spherical aberrations in the center 60% of the field of view, so images have a true color representation with virtually no distortion. If users need to change or replace objectives, Ken-a-Vision designed them to DIN standards to enable eyepieces form many manufacturers to be installed without making modifications.
A mechanical stage with spring-loaded specimen clips moves in both the X and Y axes. Each axis has its own adjustment knob, and a stage locking screw holds the stage in place when needed. Specimens are lit from below with an LED powered by either the included power adapter or permanently installed rechargeable batteries. To control the amount of light illuminating the specimen from below is an Abbe condenser and iris. An additional LED is set above the stage for use when observing solid or opaque specimens that require them to be lit from the top. The LEDs have a rheostat providing additional light control. This multifunction adjustability enables precision illumination for the perfect image.
