The active formula below can be used to model the different parameters which affect diffraction through a single slit. More conceptual details about single slit diffraction With a general light source, it is possible to meet the Fraunhofer requirements with the use of a pair of lenses. The use of the laser makes it easy to meet the requirements of Fraunhofer diffraction. The diffraction pattern at the right is taken with a helium-neon laser and a narrow single slit. Fraunhofer Single Slit Diffraction Fraunhofer Single Slit If you see any problems with this telescope calculator tool, or any of our interactive tools, please send an email to. Here is an analysis of your telescope's performance using the parameters selected above: Scope Calculator v1.0 Telescope aperture = For example, a 1st-magnitude star is 100 times brighter than a 6th-magnitude star. The higher the magnitude, the fainter the star. Approximate Limiting Magnitude of Telescope: A number denoting the faintest star you can expect to see.This tells you the closest double star you can expect to separate. Theoretical Resolving Power: The angular size of the smallest detail you can see at high magnification. ![]() (That's because, for an average adult, the pupil of the dark-adapted human eye is only 7 mm wide.) So in that case you should switch to a higher magnification. If the exit pupil is larger than 7mm, it means your eye probably won't see all the light coming from the eyepiece.
