M158C2LPB10WM Cordless Compound Monocular Microscope WF10x and WF25x Eyepieces 40x1000x Magnification Upper and Lower LED Illumination with Rheostat Brightfield SingleLens Condenser Coaxial Coarse an
The M158C-2L-PB10-WM monocular compound microscope has interchangeable 10x widefield and 25x widefield eyepieces, a forward-facing nosepiece with three DIN achromatic objectives, upper LED and rheostat-controlled lower LED illumination, coaxial coarse and fine focus, a 0.65 NA single-lens condenser, and a plain stage. The forward-facing revolving nosepiece has 4x, 10x, and 40x DIN achromatic full-glass objectives that provide high-resolution color-corrected images. The monocular viewing head has one 10x widefield eyepiece on a fixed 45-degree vertical inclination to reduce eye and neck strain and 360-degree rotation capability to provide a more comprehensive view and enable sharing. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired. The microscope has upper (episcopic) incidental illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and 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. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. Rheostat control capability allows the viewer to control light intensity. The 0.65 NA single-lens condenser and disc diaphragm control the amount of light illuminating the specimen. The plain stage is 3-1/2 x 3-1/2 inches and has an opening for light transmission and stage clips to secure the slide or specimen in place while viewing. A stage stop prevents the stage or specimen from coming into contact with the objectives. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers. All mechanical components are constructed of metal for precision and durability, and the solid-metal frame has a stain-resistant enamel finish. The microscope is powered by a 110VAC adapter (included) or by three AA batteries (sold separately) for field use. The microscope comes with five blank slides, five prepared slides, and The World of the Microscope book.

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. United Scope manufactures microscopy equipment and accessories under the brand name. The company, founded in 1996, is headquartered in Irvine, CA. What's in the Box?

Kids M50CB14 40X1000X Dual Illumination Student Microscope Gift Package Awarded 2016 Top 3 Ranking Best Kids Microscope Blue
This is a terrific beginner microscope for kids and young adults. With 3 objective lenses, and 2 eyepieces, you can use 5 magnification levels from 40X to 1000X. The magnification range is ideal for viewing microscopic organisms, like what you might find in water samples from a lake or ocean. It's also great for looking at crystal structures and metallurgical samples. The top and bottom LED illumination provide light for both translucent and opaque objects. This means you can look at ultra-thin tissue samples, or plant leaves and insects. And since the microscope is battery-powered, you can take it anywhere. The easy-to-use controls guarantee that anyone can get the hang of using the microscope in no time. The 3-lens turret can switch between the 4X, 10X, and 40X objective lenses by simply rotating. The specimen-stage has two clips to hold a slide or other object in place, while focus is adjusted by turning the large knob on either side of the microscope. A switch on the back will select the top light for opaque objects, or bottom light for translucent ones. An aperture wheel under the stage can be rotated to change the focus of the bottom light, which can increase or decrease the detail in the specimen. This kit includes 5 prepared slides, as well as a collection of tools for making your own slides. There's a Petri dish for holding liquid samples, and 5 blank slides and cover slips for mounting thin-section specimens, like tissues. There's an easy-to-use microtome for slicing specimens, and red and blue stains to improve contrast in highly-translucent specimens. A vial, stirring rod, and pipette will help prepare wet-mount slides. And, of course, there are tweezers to help with the more-delicate subjects.
