The Motic B3 Series is purpose-built for high school education and light-duty clinical microscopy, with a quintuple nosepiece and built-in Koehler illumination as standard equipment. It features a fully rotating, 30-degree inclined binocular or trinocular Siedentopf viewing head with 10X widefield eyepieces, 53mm to 72mm of interpupillary adjustment and individual diopter adjustment for each ocular tube.

Available with Achromatic Super Contrast objectives or Full Plan optics, this new microscope series brings versatility and ergonomics to a wide range of education and professional applications.

The standard Achromatic Super Contrast objectives (4x, 10x, 40xS, 100xS-Oil) are housed in a reversed quintuple nosepiece and bonded with contrast-enhancing coatings to produce images free from chromatic aberration. Optional full Plan objectives include PL4x, PL10x, PL40xS and PL100xS-Oil immersion providing flat, sharp images, making them ideal for the teaching laboratory or Life Science application.

Stage & Focus

A large double-layered mechanical stage features a spring-loaded slide clamp with dropdown coaxial controls for convenient 'eyes down' operation. The stage range of movement is 70mm x 30mm. Focusing includes high quality rack and pinion mechanics for longer life and coaxial coarse/fine focus controls for easier focusing. The fine focus scale value is 0.002mm.

The right hand focus control features finger tip controls while the dimmer switch is conveniently located immediately under the right hand focus control. Both controls can be operated during 'eyes down' observation. Safety features include a rack stop to ensure that the stage does not impact and damage the objectives or slides, and a slip clutch minimizes the risk of damage due to over-extension. The condenser is a professional centering and focus-able Abbe 1.25 NA with iris diaphragm and filter for optimal adjustments. High-quality Koehler illumination is powered by 12V 20W halogen with variable intensity.
