Walter Products 30-CXT-100-LED Basic Dual-View Monocular Compound Microscope, WF10x Eyepiece, 40x-1000x Magnification, Brightfield, LED Illumination, Abbe Condenser, Iris Diaphragm, Mechanical Stage, 110V

The Walter Products 30-CXT-100-LED Basic Dual-View Monocular Compound Microscope has two 10x widefield eyepieces (one with pointer), a reverse-mounted nosepiece with four DIN achromatic objectives, LED illumination, nested coarse and fine focus, 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The dual-view monocular viewing head has two eyepieces for simultaneous independent viewing, fixed inclination to reduce eye and neck strain, and rotation capability to provide a more comprehensive view. An eyepiece pointer in one of the eyepieces 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. Achromatic objectives provide color correction of magnified images. The 40xR and 100xR objectives are 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. The Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen. The condenser is controlled using a spiral mechanism. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. 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, and a tension adjustment ensures specimen stays focused during viewing.

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.
