Is Higher Magnification Always Better for Microscopes?

When it comes to digital microscopes, the calculation of magnification differs significantly from traditional optical microscopes.

For traditional optical microscopes, magnification is determined by multiplying the objective lens magnification by the eyepiece magnification. However, digital microscope magnification is based on the ratio of the object’s size on the display screen to its actual size. This means the larger the display screen, the higher the magnification a product can claim.

This discrepancy has led some manufacturers to advertise magnifications of 1000x or even 2000x. However, these figures often result from simply enlarging the display screen, not from genuine optical magnification.

This raises questions among consumers: Is higher magnification truly better? Does a higher price always mean better performance?

The Reality of High Magnification

Higher magnification comes with significant drawbacks:

• Smaller Field of View (FOV): The observable area becomes extremely restricted.

• Shallower Depth of Field: The focus range becomes very narrow, making it nearly impossible to observe anything beyond a single plane. This is highly inconvenient for inspection or manipulation tasks.

These limitations make extremely high magnification unsuitable for tasks requiring speed and flexibility, such as defect inspection or repair.

Qzzy: Achieving the Perfect Balance

Qzzy digital microscopes offer an optimal magnification range of 2.5x to 60x (based on an 8-inch screen). This range is ideal for applications in the PCB industry and manufacturing sectors, particularly for defect inspection and repair. Within this magnification range, users can:

• Achieve excellent depth of field and capture clear defect images.

• Maintain an appropriate field of view to examine larger areas.

• Freely use both hands to manipulate objects for repairs and adjustments.

Educating Consumers

At Qzzy, we believe it is our responsibility to inform users that higher magnification is not always better. Choosing the appropriate magnification range is the correct way to use a microscope.
