The C & A Scientific Premiere MS-01L Basic Monocular Compound Microscope has a 10x eyepiece with pointer, a forward-facing nosepiece with three DIN achromatic objectives that are parcentered and parfocal, LED illumination, nested coarse and fine focus, disc diaphragm, and a plain stage with stage clips. The monocular viewing head has a fixed inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing. An eyepiece pointer is used to identify features for students. 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. A forward-facing nosepiece eases changing objectives. The 40xR objective is retractable and spring-loaded to prevent damage to the slide or objective when focusing. A basic compound microscope is used in classroom, home school, and hobbyist settings for inspection and dissection of specimens when two-dimensional images are desired.

The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. The LED light source provides bright, cool light for working with temperature-sensitive or live specimens, and has a six-hole disc diaphragm to control the amount of light illuminating the specimen. The plain stage has an opening for light transmission, and stage clips to secure the slide or specimen in place while viewing. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers.

W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
