BelOMO 20x 四つ組ルーペ. 7mm (0.28")

The BelOMO 20x quadruplet loupe is a viewing loupe of very high quality manufactured by the Belarusian Optical Mechanical Association (BelOMO/BelOMA) which is intended for viewing small objects that are invisible or poorly distinguished to the naked eye. The 20x magnifying loupe has four achromatic, colour correction, antireflection lenses that make it possible to see the image as precise and clear as in the original. Due to the presence of four lenses the magnifier is called a quadruplet.
