Motic DM-143 Series
Digital Stereo Zoom Microscopes

The DMW-143 / DM-143B / DM-143C Digital Stereo Microscopes provide clear, unreversed 3-dimensional images sharply focused over the entire 10x-40x magnification range. The large and stable streamline base post stand features incident and transmitted halogen illumination with an auto switch transformer in the base plate. See Optical Specification Chart for other magnifications with the use of optional auxiliary objective lenses.

Both microscopes incorporate fully integrated digital cameras in the system (see description below) and are easy to operate, see Camera Specifications. These stereo zoom microscopes are fully functional and my be used independent of the integrated camera. The DM-143 Series packages present exceptional value coupled to ease of operation with a quality stereo zoom microscope, a heavy duty stand and a versatile integrated video CCD/CMOS camera.

Optical System

• Widefield eyepieces 10x / FN20 with dual diopter adjustments and 45° inclination. Interpupillary adjustment from 54 to 78mm. Viewing head rotates 360°.
• Magnification zoom range from 10x-40x with standard supplied lenses. Positive click stops at 10x, 20x, 30x and 40x. Achromatic color corrected parfocalled optical system.
• 79mm working distance with standard lenses.
• Total magnification range with optional lenses 2.5x-180x.

Focusing

• Ergonomic dual focusing knobs, heavy-duty rack & pinion with slip-clutch to prevent damage to mechanism. Tension adjustment eliminates focus “drift”.
• Working distance range with optional lenses 33-133mm.

Streamline Base Post Stand for DMW-143 and DM-143C

• Large Base Post Stand, with built-in transformer for extra stability and space saving.
• Auto-switch power supply for 100-240V, 50/60Hz.
• Stage working surface approximately 200 x 200mm deep (7.87 x 7.87").
• Includes two 95mm frosted glass and black/white contrast plates.
• Locked on stage clips.

Dimensions and Weight

• Streamline Base Post Stand (FBGG), depth: 280mm, stand width 330mm, overall height 450mm.
• Maximum specimen height 105mm.
