Imaging, resolution, sampling, light and optical systems.
- Microscope depth of field calculatorEstimate an objective’s depth of field, separating the diffraction contribution from the detector contribution.
- Microscope field of view calculatorCalculate the microscope field of view, from the sensor (rectangular field) or from the eyepiece field number (circular field).
- Microscope optical resolution calculatorCalculate lateral and axial resolution of an objective using Abbe, Rayleigh or confocal conventions, with the Airy disk.
- Nyquist sampling calculator for microscopyCheck whether your camera samples your objective’s resolution adequately: recommended step, verdict and required magnification.
- Pixel size at specimen plane calculatorCalculate the real size of a pixel at the specimen plane from sensor pixel size, magnification and binning.
- Snell’s law calculatorRefracted angle, critical angle and total internal reflection, Brewster angle. Refraction computed with its verdicts, never a NaN past the critical angle.
- Thin lens, conjugation relation and magnificationImage position and nature, magnification, optical power, with the algebraic sign convention set by the tool.
