Concave Mirror

Concave Mirror

Concave Mirror –  – Scientific Laboratory Educational Equipment A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light. Mirrors, highly slivered, optically true (spray painted  at  the  back)  with  a beautiful  ring  … Continue reading “Concave Mirror”

Convex Mirror

Convex Mirror – Scientific Laboratory Educational Equipment A convex mirror is a spherical reflecting surface (or any reflecting surface fashioned into a portion of a sphere) in which its bulging side faces the source of light. Automobile enthusiasts often call it a fish eye mirror while other physics texts refer to it as a diverging … Continue reading “Convex Mirror”





Double Concave Lens

Double Concave Lens

Double Concave Lens – Physics Optical Equipment Spherical Double Concave Lenses are highly polished and well edged. Manufactured from plate Glass, optically true.  These lenses have negative focal lengths. These lenses diverge collated incident light and form virtual images, which are seen through the lens. They are often used to expand light or increase focal … Continue reading “Double Concave Lens”





Double Convex Lens

Double Convex Lens

Double Convex Lens – Physics Optical Equipment Spherical Double Concave Lenses are highly polished and well edged. Manufactured from plate Glass. The fact that a double convex lens is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its principal axis. A double convex lens is … Continue reading “Double Convex Lens”
