Provides high magnification (up to 1000x or more) and high resolution for viewing fine details of cells, tissues, and microorganisms.

Commonly used in biological research, medical diagnostics, and educational settings for detailed examination of specimens.

A microscope is a scientific instrument used to magnify and observe objects that are too small to be seen with the naked eye. It works by focusing light or electrons to create an enlarged image of the specimen.

The lens power of eyeglasses is measured in diopters. This measurement reflects the amount of power needed to focus images directly onto the retina. When looking at an eyeglass prescription, you will see the following abbreviations:

A contact lens prescription includes more information than an eyeglass prescription. Special measurements are taken of the curvature of the eye. In addition, your child's healthcare provider will determine if their eyes are too dry for contact lenses. The provider will also see if there are any corneal problems that may prevent your child from wearing contact lenses. Trial lenses are often tested on the eyes first to make sure of the correct fit.

Uses two separate optical paths with two objective lenses to provide a stereoscopic (3D) view of larger, opaque specimens.

The terms monocular, binocular, and trinocular refer to the different types of microscope heads, each offering a distinct way of viewing the specimen.

Magnification is the process of enlarging the appearance of an object, making it look bigger than its actual size. In optics, it is the ratio of the size of the image produced by a lens or microscope to the actual size of the object being viewed.

A phase contrast microscope is an optical microscope designed to enhance the contrast of transparent and colorless specimens without the need for staining. It works by exploiting differences in the refractive index of different parts of the specimen, transforming these differences into variations in light intensity.

Parents know they need to protect their children's skin from harmful sun rays. But many forget that the eyes need to be protected, too. Nearly 5 out of 10 American parents don’t regularly provide their children with sunglasses that protect their eyes from the sun's ultraviolet (UV) rays. Sun exposure may set children up for possible vision problems later in life.

Compound Magnification is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece.

Concave lenses. These are thinnest in the center. The numerical prescription in diopters is always marked with a minus (-) symbol. These lenses are used to correct nearsightedness (myopia).

Navigate effortlessly through magnification levels and focus adjustments. Our microscopes feature intuitive controls, allowing you to concentrate on your research without the hassle of complicated settings.

Contact lenses. Contact lenses are worn directly on the cornea. Like eyeglasses, contact lenses correct refractive errors. They do this by adding or subtracting focusing power to the cornea and lens.

About 45 million Americans wear contact lenses. About 9 out of 10 people who wear contact lenses use soft lenses. In general, there are 2 types of contact lenses:

If your child is old enough, let them play an active role in choosing their own glasses. Think about the features below when buying eyeglasses for children:

Compound microscopes are suited for detailed examination of microscopic structures, while stereo microscopes are more appropriate for observing larger objects in three dimensions and for tasks that involve manipulation and dissection.

The sun can cause sunburned corneas, cancer of the eyelid, cataracts, and macular degeneration, among other problems. In addition, children are more susceptible because their lenses don’t block as much UV as adult lenses. Children also tend to spend more time outdoors than their parents, often in places where there is a lot of sun reflection. These include beaches, pools, and amusement parks. It is also important for your child to wear sunglasses in the snow as well. Most UV eye damage is the result of years of exposure.

Buy your child sunglasses that block both kinds of UV rays. Make sure the sunglasses fit correctly and are comfortable.

Earpieces that wrap around the ear (cable temples) are advised for children under 4 years. Straps may also be advised to hold the glasses in place.

Convex lenses. These lenses are thickest in the center, like a magnifying glass. They are used to correct farsightedness (hyperopia). The numerical prescription in diopters is always marked with a plus (+) symbol.

Eyeglasses. Eyeglasses are the most common form of eyewear used to correct or improve many types of vision problems. They consist of a frame that holds 2 pieces of glass or plastic to correct refractive errors. Refractive errors can include trouble seeing far away (nearsightedness or myopia) and trouble seeing close up (farsightedness or hyperopia). They can also include blurring due to an irregularly shaped cornea (astigmatism). Eyeglasses work by adding or subtracting focusing power to the cornea and lens.

A trinocular microscope head combines the benefits of binocular viewing with the capability to capture digital images or videos of specimens. It is particularly suited for advanced research, educational purposes, and industrial applications where precise imaging and documentation are essential.

A binocular microscope head utilizes two eyepieces for simultaneous viewing with both eyes, providing enhanced comfort, depth perception, and superior image quality. Ideal for professional and research settings requiring detailed observation, its design minimizes eye strain and enhances ergonomic support compared to monocular microscopes.

A monocular microscope head is a basic type of microscope head with a single eyepiece, ideal for cost-effective and straightforward applications. It is particularly useful in educational settings and for beginners, but it can lead to eye strain over long periods and lacks the depth perception provided by more advanced binocular and trinocular heads.

Microscope objectives are vital lenses that determine the magnification, resolution, and quality of the images produced by a microscope. They come in various types and magnifications, each suited for different applications and levels of detail, making them indispensable in scientific research, medical diagnostics, and educational settings.

A stereo microscope, also known as a stereoscopic or dissecting microscope, provides three-dimensional viewing of larger, opaque specimens through dual optical paths with objective lenses. It offers lower magnification (typically 5x to 40x) than compound microscopes but enhances depth perception. Ideal for tasks in biology, geology, and manufacturing, it allows comfortable, extended viewing with ergonomic adjustments.

A Compound Microscope is a type of optical microscope that uses multiple lenses to magnify small objects. It consists of two sets of lenses: the objective lens, which is closer to the specimen and provides the initial magnification, and the eyepiece lens, which further magnifies the image for the viewer's eye. Light passes through the specimen and is magnified by the objective lens, then further magnified by the eyepiece lens, resulting in a highly magnified image visible to the observer. Compound microscopes are commonly used in biology, medicine, and other scientific fields for viewing cells, tissues, and other small structures.

Capable of high magnification, which is achieved through the combination of the objective lens (typically 4x, 10x, 40x, and 100x) and the eyepiece (usually 10x).

Magnification works by bending light through lenses or using digital technology to enlarge the appearance of an object, allowing for detailed observation and analysis.

A specimen is a sample or example used for scientific study. It can be anything from biological tissues to materials, examined under a microscope or other instruments for analysis.
