Aspheric loupes are characterised by very high imaging properties:

 Even the very finest details are resolved with unchanging high contrast over the whole image field. The sophisticated optical correction, the use of aspheric surfaces and an MC coating provide the following features:

•  No color fringes at high-contrast borders
• No-fatigue vision thanks to stable image position even if the eye is moved
• Sharp focus,
• High contrast 
• No distortion over the whole format
