Galilean loupe is a type of magnifying glass or optical instrument that is commonly used for low magnification inspection or observation of small objects. It consists of a simple lens system that uses a convex objective lens and a concave eyepiece lens to create an upright and virtual image of the object being observed. All our Galilean loupes provide a wide field of view and superior depth of field which allows for more freedom of movement. Amtech loupes are made from high quality, antireflective, achromatic coated lens. Choose from a range of 4 different Galilean loupes (TTL1, TTL3, TTLA1 and TTLA3) with magnification from 2.5x to 3.5x.
