1. The objective lens has a diameter of 33. This dimension is crucial as it affects the amount of light that can enter the lens, potentially influencing the clarity and brightness of the images captured. 2. With a magnification of 22, it can greatly enlarge the subject being observed. This high magnification allows for detailed examination of small objects or distant features that might otherwise be difficult to discern. 3. The combination of an objective lens diameter of 33 and a magnification of 22 provides a relatively balanced setup. It both the ability to capture a reasonable amount of light and the power to magnify objects significantly. 4. A diameter of 33 enables better light gathering compared to some smaller lenses, enhancing the overall quality of the visual output. Along with the 22x magnification, it is suitable for various applications such as microscopy or wildlife observation. 5. The 33 diameter objective lens and 22 magnification work in tandem. They allow for a closer look at objects while still maintaining sufficient light input, facilitating clear and detailed visual exploration. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
