Microscope Magnification Calculator
Calculates total optical magnification by combining ocular eyepiece lens and objective lens powers.
⭐ Standard Laboratory Specimens & Optical Scenarios:
Light Microscope Total Magnification
Total Magnification = M_ocular × M_objective × M_auxiliary
Total Optical Magnification
400×
Active Objective: 40× High Power Dry (Blue Band)
M_total = M_ocular (10×) × M_objective (40×) × M_aux (1×) = 400×
What is Optical Magnification?
Optical magnification is the ratio between the apparent size of an object as viewed through compound microscope lenses and its actual size.
Formula & Step-by-Step Calculation
Total Magnification = Ocular Lens Power (×) × Objective Lens Power (×)
Standard compound light microscope optical power product.
Worked Step-by-Step Examples
Example 1
10× ocular eyepiece with a 40× high-dry objective lens
Solution: 400× Total Magnification
• 10 × 40 = 400×

Frequently Asked Questions
Q: What lens requires immersion oil?
The 100× objective lens requires immersion oil to prevent light refraction due to air gaps.
