A photometer used for measuring light intensity typically uses a lens that focuses the light onto a sensor or detector. The type of lens used can vary depending on the specific application and the desired level of accuracy or sensitivity required for the measurements.
A convex lens is a type of lens that can magnify an object. This lens is thicker in the middle and thinner at the edges, causing light rays to converge and create a magnified image.

A photometer is an instrument used to measure light intensity, therefore, the eclipsing binaries are best studied as we observe a periodic decrease of sunlight intensity as one member of the binary passes in front of the other.
Hypermetropia is corrected with a converging lens, specifically a convex lens. This type of lens is thicker in the middle and helps to focus light rays onto the retina, correcting the vision problem associated with hypermetropia.
The type of image formed by a lens is determined by the focal length of the lens, the distance between the object and the lens, and the placement of the object relative to the focal point of the lens. Depending on these factors, the image can be real or virtual, upright or inverted, and magnified or diminished.
Photometer is an equipment commonly used on a clinical laboratory. It has different kinds which can do certain jobs like testing blood samples. The examples of photometer used in a clinical laboratory are the flame photometer and Hemoglobin Photometer.

Another type of lens is the opposite called a reducing lens.

A reflectance photometer is typically used to measure reflection by detecting the intensity of light reflected off a surface. It measures the amount of light reflected by an object at specific wavelengths to determine its reflectance properties.
