Method Details

newtonian

public static OpticalSystem newtonian(Real primaryMirrorRadius,
 Real primaryMirrorAperture,
 Real eyepieceFocalLength)

Creates a Newtonian reflecting telescope.

Parameters:

primaryMirrorRadius - Radius of curvature of primary mirror (meters)

primaryMirrorAperture - Aperture diameter of primary mirror (meters)

eyepieceFocalLength - Focal length of eyepiece (meters)

Returns:

An OpticalSystem representing the Newtonian telescope

cassegrain

public static OpticalSystem cassegrain(Real primaryRadius,
 Real secondaryRadius,
 Real aperture,
 Real separation)

Creates a Cassegrain reflecting telescope. Uses primary concave + secondary convex mirrors.

Parameters:

primaryRadius - Radius of curvature of primary mirror

secondaryRadius - Radius of curvature of secondary mirror (negative for convex)

aperture - Aperture diameter

separation - Distance between mirrors

Returns:

An OpticalSystem representing the Cassegrain telescope

angularMagnification

public static Real angularMagnification(Real objectiveFocalLength,
 Real eyepieceFocalLength)

Calculates angular magnification for a telescope. M = f_objective / f_eyepiece

Parameters:

objectiveFocalLength - Focal length of objective (mirror or lens)

eyepieceFocalLength - Focal length of eyepiece

Returns:

Angular magnification

lightGatheringPower

public static Real lightGatheringPower(Real apertureMeters,
 Real pupilMeters)

Calculates the light-gathering power relative to the human eye. LGP = (D_aperture / D_pupil)²

Parameters:

apertureMeters - Telescope aperture diameter in meters

pupilMeters - Human pupil diameter (typically 0.007m = 7mm)

Returns:

Light gathering power ratio
