2. Hunting Scope Optical System
The optical system is the core of a hunting scope.
A typical design includes:
Objective Lens → Internal Optical System → Reticle → Eyepiece
The objective lens collects incoming light, while the internal lens system processes and magnifies the image.
The final image quality depends on:
Optical Glass + Lens Design + Coating + Alignment + Assembly
This means a scope with a large objective lens does not automatically provide better optical performance.
3. Objective Lens Technology
The objective lens is the large front lens of the scope.
Common sizes include:
-
32mm
-
40mm
-
44mm
-
50mm
-
56mm
A larger objective can increase the amount of incoming light, but it also increases the size and weight of the scope.
Therefore, objective diameter should be matched with the intended magnification and application.
4. 40mm Hunting Scope
A 40mm objective is a popular choice for compact optical scopes.
Advantages include:

5. 44mm Hunting Scope
A 44mm objective provides a slightly larger optical aperture.
It can be paired with configurations such as:
4-16×44
This combination provides a wider magnification range while maintaining a relatively manageable product size.
6. 50mm Hunting Scope
A 50mm objective provides greater light collection potential.
It is commonly paired with higher magnification systems such as:
5-20×50
or
6-24×50
The larger optical system may be suitable for users who prioritize magnified viewing and low-light optical performance.
7. Magnification Range
Magnification determines how large distant objects appear through the scope.
Common variable-power configurations include:
-
3-9×
-
4-12×
-
4-16×
-
5-20×
-
6-24×
A wider magnification range provides more flexibility, but it can also increase the complexity, size, and weight of the optical system.
8. Low Magnification
Low magnification provides a wider field of view.
This can make it easier to:
-
Scan an area
-
Observe moving objects
-
Maintain situational awareness
-
Locate a distant object
Low-power scopes are often compact and lightweight.
9. High Magnification
High magnification provides greater image enlargement.
However, increasing magnification generally results in:
-
Narrower field of view
-
Smaller exit pupil
-
Greater sensitivity to movement
-
Increased sensitivity to atmospheric conditions
Therefore, high magnification should be selected only when it provides meaningful benefits for the intended application.
10. Field of View
Field of View, or FOV, describes the visible area through the scope.
For example, a scope with a wider FOV allows users to see more of the surrounding environment.
The relationship is generally:
Higher Magnification → Narrower FOV
Lower Magnification → Wider FOV
Professional product pages should clearly specify FOV values and the corresponding magnification.
11. Eye Relief
Eye relief is the distance between the eyepiece and the observer's eye while maintaining a full usable image.
Good eye-relief design can improve:
-
Comfort
-
Viewing stability
-
Ease of use
-
Optical ergonomics
For international buyers, eye relief should be included in the technical specification table.
12. Exit Pupil
Exit pupil is the diameter of the light beam leaving the eyepiece.
The approximate formula is:
Exit Pupil = Objective Lens Diameter ÷ Magnification
For example:
A 40mm objective at 8× magnification provides:
40 ÷ 8 = 5mm
This is a useful specification for comparing optical configurations.
13. Lens Coating Technology
Lens coatings are critical for modern optical products.
Common terms include:
-
Coated
-
Multi-Coated
-

It is a suitable option for buyers seeking a traditional reticle design.
17. Mil-Dot Reticle
Mil-Dot reticles contain reference points that can represent angular measurements.
They are often selected by users who prefer angular-reference reticle systems.
Manufacturers should provide accurate reticle dimensions and calibration information.
18. BDC Reticle
BDC means Bullet Drop Compensation.
A BDC reticle provides additional reference points associated with expected trajectory conditions.
Because real-world performance depends on equipment and environmental variables, users should verify the calibration for their specific configuration.
19. Illuminated Reticle
An illuminated reticle uses an electronic light source.
Common functions include:
-
Adjustable brightness
-
Multiple brightness levels
-
Central reticle illumination
-
Low-light visibility
Illumination improves reticle visibility but should not be confused with thermal imaging or night vision technology.
20. FFP Hunting Scope
FFP means First Focal Plane.
In an FFP scope, the reticle is positioned in the first focal plane.
When magnification changes, the apparent size of the reticle also changes.
This can be useful when reticle markings are intended to maintain angular relationships across magnification settings.
21. SFP Hunting Scope
SFP means Second Focal Plane.
The reticle is positioned in the second focal plane.
Its apparent visual size generally remains consistent as magnification changes.
This can provide a familiar and uncluttered reticle appearance.
22. FFP vs. SFP Comparison
| Feature | FFP | SFP |
|---|---|---|
