A flat convex lens is a special type of lens where one side is flat and the other side is convex. So what are the applications of flat convex lenses?

optical instrument

Microscope: Used in the objective and objective lenses of a microscope to magnify and focus sample images.

Telescope: In a telescope, it can serve as an eyepiece to help users observe distant objects.

Projector: Used in a projector to focus light sources and project images onto a screen.

Photography and videography

Camera lens: A flat convex lens is a part of the camera lens used to focus light to capture clear images.

Camera lens: Similarly, flat convex lenses are also used in camera lenses for capturing videos.

laser system

Laser focusing: can be used in laser systems to focus laser beams and achieve high-precision processing or measurement.

Medical equipment

Ophthalmic examination: It can be used for fundus examination and corneal curvature measurement in ophthalmic examination.

Laser surgery: In laser surgery, it can be used to focus the laser beam for more precise treatment.

Measuring instruments

Telescopic rangefinder: A flat convex lens can be used in a telescope rangefinder to estimate the position of a target by measuring the angle and distance between the target and the observation point.
