Depth of Field Calculator

Calculate the depth of field, hyperfocal distance, and sharp focus range for any camera setup. Use this when planning shots where controlling foreground-to-background sharpness is critical.

Critical Angle Calculator

Calculate the critical angle beyond which light undergoes total internal reflection at the boundary between a denser and a rarer medium. Essential for fiber optics, prism design, and understanding optical phenomena.
