Ray Approximation: In many optical systems, light is modeled as a straight-line “ray.” This simplifies the analysis of how light interacts with different components.
Why It Matters: This concept is key to designing robust optical systems and underpins imaging and laser applications.
The Equation: $$ n_1 \\sin(\\theta_1) = n_2 \\sin(\\theta_2) $$ where \( n_1 \) and \( n_2 \) are the refractive indices, and \( \\theta_1 \) and \( \\theta_2 \) are the angles of incidence and refraction.
Key Insight: This law governs how light bends when moving between media, critical for minimizing optical aberrations.
Convex (Converging) Lenses: Focus parallel rays to a single focal point. The lens equation, $$ \\frac{1}{f} = \\frac{1}{u} + \\frac{1}{v} $$, relates object distance (\( u \)), image distance (\( v \)), and focal length (\( f \)).
Concave (Diverging) Lenses: Spread parallel rays to form a virtual image and are often used for image correction.
The simulator displays key parameters such as lens dimensions and ray trajectories, which help fine-tune optical designs for improved performance.
Use convex lens simulations to model light focusing onto sensors. Adjusting focal lengths, lens dimensions, and curvature optimizes the field-of-view and depth-of-field for cameras, telescopes, and microscopes.
Precise control over ray paths is essential for designing systems with well-collimated beams or precise focusing. Simulation insights help optimize optical assemblies for laser applications.
For advanced displays like autostereoscopic systems, optimizing lens arrays and waveguides is key to achieving high resolution with minimal distortion.
Simulations enable quick iterations and informed design decisions, refining optical configurations for optimal performance and manufacturability.
