The AmScope M500B-MS monocular compound microscope has interchangeable 10x widefield and 20x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, tungsten illumination, coaxial separate coarse and fine focus, a 1.25 NA Abbe condenser, and a plain stage with a mechanical specimen holder. The monocular viewing head has a fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing. An anti-mold head preserves optics in high-humidity areas. The forward-facing revolving nosepiece has 4x, 10x, 40xS, and 100xS (oil) DIN achromatic objectives that provide color correction of magnified images. The 40xS and 100x S objectives are spring loaded to prevent damage to the slide or objective when focusing. The 100xS oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. The fully-coated optical system provides sharp, high-resolution images. A compound microscope is used 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. Tungsten (incandescent) illumination provides bright light, and a rheostat controls the amount of light emanating from the lamp. The 1.25 NA 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 plain stage has clips to secure the specimen in place, and is 4-3/8 x 4-3/4 inches (110 x 120mm) (W x D; where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). A mechanical specimen holder can be added to the plain stage to provide precise movement, perform measurements, and record coordinates. Separate coaxial coarse and fine focus eases focusing for left- and right-handed viewers, and a rack-and-pinion mechanism provides precise and secure focusing. Focus tension control prevents stage drift. All the mechanical parts of the microscope are constructed of metal to provide durability and resistance to wear. The metal frame has a stain-resistant enamel finish for durability and to ease cleaning.

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.

Together, these kept my kid entertained forever! Big note though- if that's something they like, you might really want to get some blanks so you can explore puddle water, your cheek cells, plant leaves, etc).
Great great microscope. Much better than what I'd hoped for. Please spend the extra money on one that's quality. Don't get one with a mirror for a light source, or that is made of plastic (you'll be very disappointed in the lens quality), or that uses only a battery (there's a reason this has a big fat cord, and it's because the light is nice and bright!). It's a whole lot easier to learn on a quality piece of equipment and then dumb it down if necessary, than to always have to try to figure out new things because you've been taught on something much simpler and of lower quality (well, that's my opinion, anyway...it IS a review!).
Well-made, easy to use, and reasonably priced.
If you go to the website they have a picture too, showing where the teeny tiny screw is.
There is a small screw on the side of the eye tube. Use a tiny
phillips head screw driver to remove the screw so that you can
take the eyepiece out and insert a new ones. If you need to turn the
microscope upside down for any reason, make sure to tighten this
screw, or remove the eyepiece first.
This particular microscope is definitely worth what we paid for it. It includes *almost* everything you need to get started. The only thing I did supplement with (besides the prepared slides) is a set of blank glass slides and covers. I would recommend this microscope to anyone.
