so that the liquid doesn't slide off
it has a convex lense because if it had a concave lense it wouldn't magnify, same with a flat lense.
if the strip will flat we can measure its thickness easily but if it is not flat i.e. its surface is irregular then it will thick only from some points and its other area will be thin and we cannot measure its thickness easily.same is the reason for wire.
ON average it should take a few minutes to get to the right temperature.
There are several main reasons a heating curve might have one or more flat spots: Heating water, as it moves from solid (ice) to liquid, a huge amount of energy is required to get past that temperature. That takes time and the substance will have nearly the same temperature all the way through thawing. There is an even larger flat spot for the boiling point. Heating a metal, even without having it go liquid or gaseous, the metal may go through a transition phase especially if it is an alloy. Heating a substance like a painted metal, the heating will go through a flat spot during the time that the coating is boiling off. This is one of the ways that the space shuttle keeps cool during re-entry: Some of the outermost layer of the insulating blocks vaporizes, keeping the substrate at a nearly constant temperature.
A confocal microscope works by a laser shining on two mirrors mounted on motors which allows it to scan the sample then the emitted light is focued through the pinhole to a detector which relays an image to the lens.
A stage is a flat surface where the slide is placed and Holds a lens

The flat microscope platform is on which an object is placed for viewing is called the stage.
Stage
The stage is the flat piece that the slides are placed on. The two stage clips hold the slide down.
the stage on a microscope is where you would place the object being microscoped. you would put the object lets just say a leaf, on the flat part with lenses above
compound light microscope (light passes through the specimen and produces a flat image)
Assuming that you are referring to a microscope wet mount slide, it is used to hold the liquid flat in place for the observation of miniature creatures in the liquid.
The stage of a microscope is the small flat platform upon which you mount your specimen slides. Stage clips - usually a pair, are designed to hold the specimen slide securely in place.
1. Always carry the microscope in an upright position with two hands. One hand should support the base and the other should be on the on the arm. Use lens paper and lens cleaning solution to clean the lenses on the microscope. Paper towel will scratch the lenses. Use a soft cloth to clean other parts of the microscope. Lens cleaning fluid and paper is a must. Do not substitute paper towel, which is far too coarse and will scratch the lenses. Always set your microscope on a clean, flat surface. 5. Always remove slides from the stage and rotate the nosepiece to the lowest power before returning the microscope to its storage area.
A microscope slide is used to hold objects underneath a microscope for examination. It is a thin, flat piece of glass that is usually held to a microscope with clips.
A cover slip is a thin square of glass that you put over a specimen on a microscope slide. The cover slip stops the specimen from drying out, and squishes it so that light can get though it easier
