The four graduated scales include a 0.07mm dot, a 0.15mm dot, a 0.01mm crosshair, and a 0.01mm single line. Brightly illuminated grid lines on precision-ground glass construction provide accurate readings. The slide comes with a protective case. 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. United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA. \u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Microscope calibration slide for calibrating microscope eyepiece and camera reticles\u003c\/li\u003e\n\u003cli\u003e✅ Four graduated scales include 0.07mm dot, 0.15mm dot, crosshair, and single line\u003c\/li\u003e\n\u003cli\u003e✅ Brightly illuminated grid lines on precision-ground glass construction provide accurate readings\u003c\/li\u003e\n\u003cli\u003e✅ Includes case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e✅ Product Dimensions:\u003c\/strong\u003e 3.5 x 1.7 x 0.8 inches\u003c\/p\u003e\n\u003ch3\u003eShipping \u0026amp; Guarantees\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ FREE standard shipping within the United States (3–6 business days)\u003c\/li\u003e\n\u003cli\u003e✅ 100% money-back guarantee for lost or damaged items\u003c\/li\u003e\n\u003cli\u003e✅ Secure checkout with encrypted payment processing\u003c\/li\u003e\n\u003cli\u003e✅ Shipping via UPS, FedEx, and USPS\u003c\/li\u003e\n\u003cli\u003e✅ Ships to lower 48 states only (no PO Boxes \/ APO \/ FPO)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReturns\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ 30-day hassle-free returns\u003c\/li\u003e\n\u003cli\u003e✅ Items must be unused and in original packaging\u003c\/li\u003e\n\u003cli\u003e✅ Full refund if item is not delivered\u003c\/li\u003e\n\u003cli\u003e✅ Guaranteed delivery within 6–7 business days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePayment Methods\u003c\/h3\u003e\n\u003cp\u003e✅ Credit Cards, PayPal, Shop Pay, Apple Pay, Google Pay, Amazon Pay, Meta Pay\u003c\/p\u003e\n\u003ch3\u003eCustomer Support\u003c\/h3\u003e\n\u003cp style=\"text-align:left;\"\u003e✅ Questions?
