Carson JS-40 magnifying glass - 2.5x (75 mm) with 5x spot lens
Looking for a reliable and comfortable handheld magnifier for everyday use? The Carson JS-40 magnifying glass is a practical choice for anyone who needs a clear and sharp view of fine details - whether you are reading small print, working with components, studying maps or learning in school. The generous 75 mm lens diameter provides a sufficiently large field of view, making work with the loupe pleasant and natural.
Two optical elements in one tool
The JS-40 combines two optical elements in a single device. The main lens, with a diameter of 75 mm and 2.5x magnification, offers a wide overview and is ideal for comfortable reading or inspecting larger surfaces. The integrated 5x spot lens is designed for a quick look at extremely fine details - such as small-print text, component markings or material structures. Switching between the two modes is instant and intuitive.
Ergonomic design for extended use
The handheld magnifier with a 75 mm lens is well balanced in the hand thanks to its size - it is not so small that the field of view becomes limiting, yet it is not bulky either. The ergonomic handle allows for long-term comfortable use without fatigue, which you will especially appreciate during extended work in the office or while studying.
Wide range of applications
This magnifier is at home in a wide variety of settings:
- School - useful for students and teachers during science lessons or work with written materials
- Office - makes it easier to read contracts, invoices and small-print documents
- Seniors - the combination of a large lens and the additional 5x spot is particularly appreciated by users with reduced vision
- Hobbyists and collectors - provides a detailed view of items of interest, components or collectibles
