What is the difference between an optics lens and an anatomy lens?
The lenses have different responsibilities. A optic lens is often concave which means it fold inward. An anatomy lens is mostly convex which means it folds outwards. Both lens' help you see.
What is a 4 letter name for eyepiece?
Lens.
What is a CPU camera lens?
A CPU camera lens has electrical contacts on it. This means that it also has the auto focus option, which is where the lens will focus itself.
When curvature lens is bigger what happens to the focal point?
When the curvature of a lens is larger, the focal point moves closer to the lens. This means the lens has a shorter focal length and will converge light rays at a point closer to the lens.
In relation to cameras what is a USM lens?
If a camera lens has the letters USM printed on it, it means UltraSonic Motor. This means that the motor is built into the body. These lenses tend to cost a little more than a lens without a USM.
What part of the eye starts with the letter L?
The Lens.
What does achromatic mean?
Achromatic means "without color". An achromatic lens is a lens that is virtually free from prismatic color distortions.
Which lens is a converging lens a double-convex lens or a spherical-convex lens or a plano-concave lens or a convexo-concave lens?
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
How much is letter e magnified under lpo?
The letter "e" is magnified 1000x under an LPO (Low Power Objective) microscope. This means that the image of the letter "e" appears 1000 times larger than its actual size when viewed through the LPO lens.
What is a bifocal lens?
bifocals are glass lens that you place upon your nose & push up. they help you see better & / read
What is the relationship between the focal length and magnification of a lens?
The relationship between the focal length and magnification of a lens is inversely proportional. This means that as the focal length of a lens increases, the magnification decreases, and vice versa.
What are the differences between a lens with an aperture of f 1.4 and a lens with an aperture of f 1.8?
A lens with an aperture of f 1.4 allows more light to enter than a lens with an aperture of f 1.8. This means the f 1.4 lens can create a shallower depth of field and better low-light performance compared to the f 1.8 lens.
