Designed as a classroom instrument for teaching forensics and comparative sciences, Ken-a-Vision's 220 VAC European version of the TU-19243C-230 Comparison Scope 2 Microscope features two identical microscope bodies connected by a bridge with a single binocular head for making detailed side-by-side comparative observations. It can run from a 220 VAC European voltage outlet or a permanently-installed rechargeable battery for use in the field. The battery has an 8-hour charge time, with a 40-hour runtime.
The binocular head has two 10x eyepieces - one with an integrated pointer - set at in a 30° angle for comfortable both-eyes-open observations that preserves stereoscopic vision with a depth of field that monocular heads are unable to provide. This 3-D vision is especially important when viewing objects like coins, fabrics, stones, and just about anything beyond slides.
Two identical bodies, connected by a bridge, each feature a four-objective 360° rotating turret with click-stop positions at each lens. The four objectives from 4x to 100x produce a broad magnification range of 40x to 1000x making this microscope a versatile observation and educational tool. 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 in the center of the viewing area.
If users need to change or replace eyepieces and objectives, Ken-a-Vision designed them to DIN standards to enable parts from 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. For additional versatility, the TU-19243C-230 features upper and lower LED illumination that allows transparent specimens like prepared slides to be lit from below, and opaque subjects to be let from above. An Abbe condenser and iris diaphragm under the stage in addition to a rheostat for the LEDs provides precision illumination for all specimens.
