Optical Theory and Calculations
Total Magnification: M = M₀ × Mₑ
Objective magnification: M₀ = v₀ / |u₀|
Eyepiece magnification: Mₑ = 1 + (D / fₑ) where D = 25 cm
Lens formula: 1/f = 1/v - 1/u
Current configuration:
• Objective magnification (M₀) = 5.0
• Eyepiece magnification (Mₑ) = 6.0
• Object distance (u₀) = -1.50 cm
• Image distance (v₀) = 7.50 cm
• Eyepiece object distance (uₑ) = -4.17 cm
• Lens separation = 11.67 cm
