What is a Concave Mirror?
A concave mirror is a spherical mirror with a reflective surface that curves inward, resembling the interior of a sphere.
Due to its unique geometry, concave mirrors can converge parallel light rays to a single focal point, making them essential in optical systems requiring light focusing, magnification, and image projection.
What is the difference between a concave and a convex mirror?

![]()
Concave Mirror → Parallel rays converge at a real focus.
![]()
Convex Mirror → Parallel rays diverge, appearing to come from a virtual focus behind the mirror.
Key Features of Concave Mirrors
- Light Convergence: The mirror can effectively reflect and focuse incoming light.
- High Reflectivity: Coated with aluminum, silver, or dielectric layers for maximum efficiency.
- Customizable Parameters: Chenyu can customize various diameters, curvatures, and coatings.
- Durability: Scratch-resistant surfaces with protective overcoats, suitable for most harsh environments.
- Precision Manufacturing: Low surface roughness and tight tolerance control.
Applications of Concave Mirrors
- Telescopes & Astronomy – It can be used in reflecting telescopes to collect and focus distant starlight.
- Laser Systems – For beam focusing and optical cavity designs.
- Medical Instruments –Some dental mirrors and diagnostic devices also need the mirror.
- Lighting & Projection – Concentrating light in lamps, projectors, and headlights.
- Solar Energy – Focusing sunlight in solar furnaces and thermal power systems.
