AMTECH ErgoAm is a refractive loupe that uses lenses to refract, or bend, light in order to create a magnified image of an object being viewed. The advanced optics allows you to keep your head completely upright while working, which reduces strain, especially during long procedures. Try it out during the demo to see if it’s the right loupe for you. AMTECH ErgoAm comes in 3.5x, 4.0x, 5.0x and 6.0x magnification.
