Diffraction Limit Calculator vs Hologram Diffraction Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Diffraction Limit Calculator
Calculate the smallest resolvable spot or feature that an optical system can distinguish, based on wavelength and aperture. Use it when designing cameras, telescopes, or microscopes where resolution is critical.
- Answers
- Angular Resolution (μrad)
- Inputs
- Wavelength, Aperture Diameter, Focal Length, Diffraction Criterion
Hologram Diffraction Calculator
Find the diffraction angle of light leaving a holographic grating for any order, wavelength, and incident angle. Useful for designing holographic optical elements, spectrometers, and display systems.
- Answers
- Diffraction Angle (degrees)
- Inputs
- Grating Period, Illumination Wavelength, Incident Angle, Diffraction Order
