Ramsden’s Eyepiece and at the back of the field lens in Huygens’ Eyepiece. A micrometer scale for measurement can be placed coinciding these images.
eyepieces, Ramsden’s eyepiece, Huygen’s eyepiece, Gaussian eyepiece, comparisons o For refraction at the first surface (from air to lens) we can write.
eyepieces – Constant deviation spectrometer – Calculation of Difference between Huygens and Ramsden eye piece: Write about coma in lenses.
State the merits and demerits of Ramsden eyepiece 29. Write the conditions for minimized spherical and chromatic aberration 30. Why the Huygens’ eyepiece isLecture 10: Stops, eyepieces. • Aperture stop. • Entrance, exit pupil. • Field stop. • Eye pieces. – Ramsdens eyepiece. – Huygens eyepiece
