The AmScope M500A-LED cordless monocular compound microscope has interchangeable 10x widefield and 25x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, LED illumination, coaxial separate coarse and fine focus, a 1.25 NA Abbe condenser, and a plain stage. 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. The head 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. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens, 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). 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. The microscope can be powered by a 110V wall outlet or by three AA rechargeable batteries (included). Batteries can be recharged using the included power cord/recharger.

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 AmScope. The company, founded in 1996, is headquartered in Irvine, CA.

Un microscopio muy decente para escolares. La calidad de construcción metálica y el ajuste fino del enfoque ayuda muchísimo al igual que el porta muestras desplazable. La calidad óptica estándar por lo que se pueden adquirir nuevos objetivos u oculares. por lo que se adapta a las diferentes tipos observaciones .Los x2000 es complicado llegar y que la solución que viene para alimentarlo es bastante mala , por eso no le doy las 5 estrella.

Light stopped working after light use. Warranty requires buyer to pay two way shipping. What a joke. It's probably cheaper to buy a new one instead of paying two way shipping. I wanted to support a US based company and was willing to pay more for quality. You can find dozens of Chinese brands for a fraction of the price. Is this what we get when we try to support local business and pay more? Lesson learned. Very disappointed!

It's my first Microscope but I like it!I recommend buying AmScope Graduated Mechanical Stage for Compound Microscopes - it's necessary for moving slides with precision;and also buy usb digital camera for microscopes - it increases ability to see objects in higher magnification.PS: don't forget to buy slides.
