BelOMO 20X Quadruplet
This is the a high quality 20x quadruplet. A quadruplet means that there are a total of four lenses.
The housing for the 20x is the same metal enclosure as is found on the popular 10x triplet, it will not break like some other cheap hand lenses. The viewing area though is smaller, as is the focal length. The lenses are coated for improved quality and longer life. The lens on this quadruplet is 17.5 mm diameter, 7 mm viewable. The large lens area allows for collection of the maximum amount of light gathering. True 4 element achromatic lens provides a bright and crisp view without color distortion. Focal distance is 8 mm. Can be disassembled for easy cleaning. For this price, you can't go wrong with this one. Buy two or three, you won't regret it.
The focal length on any 20x lens is very small, for this reason a 20x loupe is not meant for all uses. Our 10x is a much better all around hand lens. A 20x loupe is suitable for viewing small areas under high magnification. It is often used for viewing flat objects where a large focal length is not needed.
