diffraction diameter on image sensor calculator online
Use diffraction diameter on image sensor online for wavelength nm, f number, pixel pitch um. Geometric or data-budget estimate. Sensor behavior, processing, focus breathing and recording overhead are excluded unless explicitly modeled.
How to use it
Enter wavelength nm. Set f number, pixel pitch um. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
airy_diameter_um = 2.44*wavelength_nm/1000*f_number; airy_diameter_pixels = 2.44*wavelength_nm/1000*f_number/pixel_pitch_um (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply diffraction diameter on image sensor to the case below, keeping the displayed units and assumptions. Geometric or data-budget estimate. Sensor behavior, processing, focus breathing and recording overhead are excluded unless explicitly modeled.

Exposure equivalence, depth-of-field equivalence and file storage describe different questions. Review whether a value is a focal length, a crop factor, a shutter time, a frame rate or a bitrate before calculating.
Limitations and common mistakes
- Geometric or data-budget estimate. Sensor behavior, processing, focus breathing and recording overhead are excluded unless explicitly modeled.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
