A flat surface is a two-dimensional space with no curves or angles, such as a table, floor, or wall. It is a level plane that remains constant and uniform across its expanse.
A light ray typically undergoes two refractions as it travels through a lens: one at the entrance surface and another at the exit surface. These refractions cause the light ray to change direction based on the shape and refractive index of the lens.
Convex refers to a shape or surface that curves outward like the exterior of a circle. In mathematics, it describes a set where any line segment connecting two points within the set lies completely within the set. Convexity is often used in optimization and geometry to simplify problem-solving.
A diverging lens, such as a concave lens, will produce an inverted image when the object is located more than two focal lengths away from the lens. This is because the diverging lens causes light rays to spread out, resulting in the image being flipped vertically.

The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.

The bulbs are replaceable behind the lens, so the lens (two screws for the front and 4 for the back) must be removed to change the bulbs.

The lens comes off. There's two indentations opposite the switch, on the front edge of the lens. Use a small flat bladed screw driver to remove the lens.
Two numbers, such as 4x32, indicate the magnification (4 times) and the size of the front (objective) lens- 32 mm. A bigger lens is usually brighter. Three numbers, such as 6-24x42 or 6x24x42 will indicate a variable power scope- from 6 to 24 power, with a 42mm front lens.

remove the two light lens be careful not to break them. then remove the two torx screws behind the lens. give a slight pull down on the front of the console to remove the two clips and you are done.
