The B450 binocular compound microscope is designed for educational and professional use. The medium-sized profile offers streamlined ergonomics with plenty of working room. The heavy-duty metal build and enamel coating will last for many years through rigorous use. High-quality semi-plan achromatic optics and LED transmitted illumination produce sharp, high-contrast images with improved field flatness for biological applications. To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on the left ocular tube to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain. The head can also be rotated 360° to accommodate multiple users. Various eyepieces can be used to increase the overall optical magnification.The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stages 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. An adjustable height limit can be set to prevent damage to the lenses and specimens while focusing. The LED sub-stage lighting provides cool, energy-efficient illumination. The 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.
