The B120B-WM compound binocular microscope has pairs of 10x widefield and 20x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield (BF) LED illumination, a 1.25 NA Abbe condenser, and a double-layer mechanical stage. The Siedentopf binocular head has interchangeable pairs of 10x widefield and 20x widefield eyepieces with 53 to 77mm Siedentopf inter-pupillary adjustment, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to provide a more comprehensive view and enable sharing. Dioptric adjustment accommodates individual eye-strength differences. The forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that combine with the eyepieces to provide color correction of magnified images at eight magnifications. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil objective provides increased resolution over a standard objective. 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. 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 double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. Separate coarse and fine focus knobs speed focusing. The enamel-coated cast-steel body is durable and resistant to stains and corrosion. The microscope comes with The World of the Microscope: A Practical Introduction with Projects and Activities.

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

Size: Feet & nbsp; | & nbsp; Color: White, A Family Company located in the USA, is proud to manufacture this high quality and durable coaxial cable. This cable is available in Black and White, and comes in lengths from 1 foot to 200 feet (including our most popular lengths of 6 feet, 10 feet, 25 feet, 50 feet, 75 feet, and 100 feet). The center conductor is made of high grade Solid Copper (SC) and has been swept to 3.0GH z, making this a great application for Satellite, Cable, Wireless (including cell services), and Communication uses. The use of solid-copper allows for very low voltage drop along the center conductor over long runs. With very low signal attenuation ( 2.75 dB at 750MHz for our 50' cable) it can be used on long runs without the loss of signal or picture. We use high grade 360 degree compression connectors to ensure that this cable remains water and weather proof, without the loss of any signal. This ensures that the ends can withstand pulling, weather, extreme hot and cold (rated up to 167 degrees F). The coaxial shielding is 60% aluminum magnesium alloy braid and 100% solid aluminum foil (including an 18% overlap) to ensure that there is no interference from neighboring or rouge signals. The outer jacket is a flexible UV resistant PVC and has been tested to be used in many extreme conditions for use both inside and outside. The dielectric center is made from gas injected foam PE and has an almost perfect consistency of 75 Ohms +/-3 throughout the entire length of the coax cable. The outside diameter of the cable is 0.27 inches, about 6.85 mm, with the connectors being slightly larger at. 4375 (7/16) of an inch ( 11.11 mm). The cable also has length markings every two feet on the side to make it easier to cut to length, if you need a shorter wire. We also offer a repair and splice kit for those who would like to cut and reinstall the ends on the wire. The kit comes complete with instructions and free technical support. We back our product 100%, with free returns, as well as
