82-M-0820 Magnifying Glasses & Loupes > Monoculars with near focus
The Specwell M-820 Monocular is a handheld telescope with 8x magnification and a 20 mm aperture, which can be used to observe objects at a minimum working distance of 300 mm up to infinity.
Specwell monoculars make excellent visual aids due to their high light sensitivity, true image, and magnification. Whether as a portable spyglass or reading aid for private use. Also used in industrial applications for installation and service. The magnification and working distance for short and long ranges allow for a wide spectrum of applications.
Note that the depth of field is limited in the near range, so precise focusing is required. The image is not inverted. Both lens systems (eyepiece and objective lenses) are achromatic and feature an anti-reflective coating as standard. The compact design is a significant advantage for recreation, as monoculars are significantly smaller than a regular binocular. Case included.
