What is known is the optical construction: a roof type lens structure with an anti-sidelight 45 degree design, a 20x mirror magnification, an 18mm objective lens diameter and a 16mm eyepiece diameter. These values define the core build of the unit. No further material claims are made because none are provided.

Size and Practical Fit

The product size is 33 x 94 mm, making it a compact item for carrying with a phone. The exit pupil distance is 3mm and the eye point distance is 9.6mm. The observation distance of 3 metres to infinity and the 250m/1000m (16°) field of view give a clear idea of where it can be used. All measurements are as stated in the source text.

Uses and Placement

This lens is intended for smartphone-based observation at distances from 3 metres to infinity. It can be used in outdoor settings where a closer view of a distant subject is wanted, and the 16° field of view offers a defined viewing area.

Event or Professional Use

With a 20x mirror magnification and an 18mm objective lens, the lens can be used for viewing events or scenes where a phone camera needs extra reach. The roof prism and anti-sidelight 45 degree design are part of its optical setup. The 250m/1000m field of view and 3 metres to infinity observation distance are the stated performance limits. It is available in model options 12X, 14X and 8XL, and in black or white.

Everyday Home Use

For everyday use, the compact 33 x 94 mm size makes it easy to keep with a phone. The 3mm exit pupil distance and 9.6mm eye point distance are fixed values from the source. It can be used for looking at distant objects from a garden, balcony or other open space. The quantity options are 1pc or 2pcs, so a spare can be selected if needed. No other home uses are claimed beyond the stated observation range.

Benefits and Buying Value
