Walter Products 40-CXM-LED Basic Monocular Compound Microscope, WF10x Eyepiece, Plan Objectives, 40x-400x Magnification, Brightfield, LED Illumination, Iris Diaphragm, Plain Stage, 110V

The Walter Products 40-CXM-LED Basic Monocular Compound Microscope has a 10x widefield eyepiece with pointer, a reverse-mounted nosepiece with three DIN plan achromatic objectives, LED illumination, nested coarse and fine focus, 0.65 NA condenser with iris diaphragm, and a plain stage. The monocular viewing head has a fixed inclination to reduce eye and neck strain, and rotation capability to enable sharing. An eyepiece pointer is used to identify features for students. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. Plan achromatic objectives provide color correction and improved focus over the entire range of the viewing field. Parcentered and parfocal objectives ensure that the image stays centered and focused when the magnification is changed. 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. An iris diaphragm optimizes 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. A stage stop prevents the stage or specimen from coming into contact with the objectives.

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.
