The National Optical DC-128 Digital Compound Monocular Microscope has a 10x widefield eyepiece with pointer, a forward-facing nosepiece with four DIN achromatic objectives that are parcentered and parfocal, LED illumination, separate coarse and fine focus, 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The 0.4MP camera has a CMOS color sensor, image capture and editing software, and USB 2.0 output to capture or display still or video images on a computer or projector. The monocular viewing head has a fixed inclination to reduce eye and neck strain. An eyepiece pointer is used to identify features for students. A forward-facing nosepiece eases changing objectives. Rotation positions with secure, positive stops ensure accurate positioning and support a range of magnification options. Achromatic objectives provide color correction of magnified images. Parcentered and parfocal objectives ensure that the image stays centered and focused when the magnification is changed. The 40xR and 100xR objectives are retractable and spring loaded to prevent damage to the slide or objective when focusing. The 100xR objective is also an oil objective that provides increased resolution over a standard objective. A digital compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired, and where image capture, detailed records, or documentation is required.

The 0.4MP digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to a computer or projector. It includes image capture and editing software that provides still image and live video capture and editing capability, including measurement functions. The software supports the Motic SFC file format and is compatible with Windows XP and above, and Mac OS X. The camera has a USB 2.0 data port (cable included).

The microscope has lower (diascopic) Brightfield illumination that transmits light
