Full Page Fresnel Lens Magnifying Sheets. These are good quality magnifying sheets. They are great for reading newspapers, books and menus. Each 3X magnification sheet measures 7 x 10.25 inches with no boarder. They are made from Flexible high quality optical PVC. This allows them to be thinner with less distortion then thicker 3X magnification sheets and also makes them very lightweight and easy to hold. Optical PVC is also virtually shatterproof. Despite being flexible, they can still be held level over a surface with just 3 fingers on one corner or a side as pictured. Each sheet is protected in a reusable protective plastic sleeve. Lens Specifications: 7.00" x 10.25" (Inches). Thickness: 0.4mm. Weight: 26 grams. Material: optical PVC. Groove pitch: 0.3mm. Focal length: 300mm. Magnification: 3X.
Compact Versatility This petite and portable digital weight scale has the accuracy to meet a high range of needs with consistent and reliable results. Quickly measure ingredients, postage, gems, medication and more with a weight capacity of up to 2000 grams. Calculate in g, oz, tl, ct, and gn and convert between units instantly with a single press of a button without having to re-measure. The bright blue backlit LCD screen displays the weight in real time as more ingredients or pieces are added to the platform. It's quick and easy to manually calibrate and the scale includes auto taring capability for easy weight subtraction and summation. The scale is built with high quality stainless steel for a longer lifetime and easier maintenance. It's small and lightweight, making it easy to store and take on the go without excessive added weight, bulk or hassle. Count Pieces & Parts This digital table-top scale takes the work out of counting large quantities of small pieces. Instead of tediously separating and counting hundreds of parts or pieces through manual labor, simply pour them onto the scale platform and the scale will have the counted amount accurately calculated in less than a second. This feature is incredibly helpful for hunting, jewelry, and cooking. It's simple technology for smart living. To adjust the idle time for the auto off function: 1.Â Â Â Turn on the scale and press and hold the 'T' tare button until a default number appears on the screen. 2.Â Â Â The number on the screen indicates the idle time in seconds needed for auto-off. 3.Â Â Â Press the 'M' unit button to cycle through the preset auto-off options: 60, 120, 180 and 0 seconds. 4.Â Â Â Once you're at the desired amount of time, press the power button to confirm your selection. NOTE: The '0' seconds option deactivates the auto-off function.
A 3x magnifier with a rubberized handle, tucked in an acetate gift box. Unfold the handle and give the rubberized portion a light tug to reveal the battery compartment. Insert one AAA battery, replace the handle and slide the ridged button up to illuminate the long-lasting LED light. (LED light lasts for 8 continuous hours, or 100,000 hours if used only intermittently.) Powerful magnification and light are now in your hands for on-the-spot magnification of reading materials or hobby-work. The scratch-resistant acrylic lens measures 2" x 3" - the perfect size for using while still being comfortably portable. Product size shown is with the handle folded in. The handle itself measures approximately 4" long. Product dimensions (imperial): 4.25 inch H x 3 inch L x 0.625 inch W Product dimensions (metric): 107.95 mm H x 76.20 mm L x 15.88 mm W
AmScope Optical Glass Lens All-Metal LED Compound Microscope, 6 Settings 40x-1000x, Portable AC or Battery Power
Manufacturer: United Scope LLC.
AmScope M100C-LED 40x-1000x All-Metal Student Cordless LED Field Biological Compound Microscope with All Optical Glass Lenses From Manufacture AmScope M100C-LED is the most cost effective yet high quality biological microscope for young scientists and scientific enthusiastic age eight and up. It is ideal for viewing cell tissues, bacteria, and fungi in both self-prepared slides and pre-made-slides, such as onion cells, leaf cells, cheese bacteria, etc. It makes the microscopic world within the reach to everyone. Built to Last AmScope M100C-LED comes with all glass optical elements and solid metal body. The microscope provides sharp clear images and will last long enough to cover all the way from elementary to high school. The sturdy metal construct offers stable images at high magnification levels instead of shaking ones. The build-in battery slot uses three AA batteries to power the microscope on-the-go, and an 110V-4.5V transformer can be plugged in when using indoor setting. Excellent Optics AmScope M100C-LED features five levels of magnification settings that produce crystal clear image without any frustrations. Glass achromatic objectives minimizes aberration and last longer. About Microscopes 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, o...

â€œElementary, my dear Watson.â€ The Lighted 5â€ Round Magnifier evokes the signature style of that great literary detective, but updates a classic look with a black, ergonomic handle, silver-tone lens frame, and the utility of a super bright LED. This is the largest of our round magnifiers, and with 2x magnification and our most powerful 6x bifocal, it can handle large-scale projects down to the finest detail. The lens frame projects out on both sides, protecting the lens surface when the magnifier is set down. The crisp, white LED light enhances subtle detail and increases the contrast of text. Ideal for art aficionados, stamp and coin collectors, readers of maps and manuscripts - in short, anyone who needs to see more than what first meets the eye.
