Aluminium Eyeglass Focal Length 2.5″

Description

Ideal for close-up work, offering higher magnification and precision useful for detailed tasks such as watch or jewellery inspection.

A 2.5inch focal length refers to the distance the object must be placed from the lens to be in a clear focus.

To get a sharp image, the object should be positioned about 2.5inch (approx. 6.35cm) from the lens a shorter focal length generally corresponds to higher magnification.

Therefore, a 2.5inch focal length lens offers greater magnification than lenses with longer focal lengths.

It allows the viewer to be closer to the object, making it ideal for examining finer details but with a more restricted field of view compared to longer focal lengths.

It is made out of anodized aluminium which offers increased durability, corrosion resistance, and aesthetic appeal.
