A prismatic loupe is a type of magnifying instrument that uses prisms to create a magnified and corrected image of an object being viewed. Unlike a Galilean loupe, which uses only lenses to magnify the image, a prismatic loupe uses prisms to redirect and focus the light, which can result in a clearer and more precise image. Prismatic loupes can also correct for some of the optical aberrations that can occur in Galilean loupes, such as chromatic aberration, which can cause color fringing around the edges of the image. Prismatic loupes are typically more expensive than Galilean loupes, but they can offer higher magnification and better image quality. They are available in a range of magnification levels and working distances, and can be customized to meet the specific needs of the user. Amtech Prismatic TTLA2 comes in 4.0x and 5.0x Magnification.
