Concave Mirror FL10, FL15, FL20

Concave mirrors with focal lengths FL10, FL15, and FL20 are high-precision optical components designed with an inwardly curved, reflective surface that converges incident parallel light rays to a focal point. These mirrors are widely used in physics education, optical experiments, and scientific demonstrations to illustrate the principles of reflection, focal point behavior, and image formation.

Key Features:

• Focal Lengths:
  • FL10: Focal length of 10 cm – produces sharper convergence of rays, suitable for short-range experiments.
  • FL15: Focal length of 15 cm – ideal for medium-range optical applications and educational use.
  • FL20: Focal length of 20 cm – allows for longer image distances and broader demonstrations.
• Surface Type: Spherically concave reflective surface, typically aluminized or silver-coated for high reflectivity.
• Material: Made from high-quality optical glass or acrylic with a polished surface and protective backing for durability and clarity.
• Mounting Design: Often comes with a rim or flat back to enable secure placement on mirror stands or holders for ease of use in laboratories.
• Image Characteristics: Capable of producing real and inverted images when the object is beyond the focal point, and virtual, upright, magnified images when the object is within the focal length.

Applications:

• Demonstrations of light reflection, image formation, and mirror equations in physics and optics.
• Use in experiments involving focal point location, ray diagrams, and converging systems.
• Employed in optical instruments like telescopes, solar concentrators, and headlamps.
• Essential in classroom optics kits for hands-on learning of fundamental concepts.

These concave mirrors (FL10, FL15, FL20) are vital educational tools that deliver reliable performance and clarity, making them indispensable for teaching and experimentation in optics and physical science.
