Seeing and Feeling is Believing Micro250 pictured with the Oakley Half Jacket; multiple frame options available The Micro250 is the lightest loupe in clinical magnification that provides you with an exceptional field-of-view (up to 6 inches) and an extra long depth-of-field (as long as 14 inches). The Micro250 only weighs 10 grams* – compared to up to 30 grams for other 2.5x loupes – and when combined with our patented Ergo Frame or one of the many frames from our exclusive Oakley line, you will hardly feel a thing on your face. (*weight of loupe ocular pair) The Micro250 helps you see and feel your best since it combines the best in vision and ergonomics with SurgiTel’s ErgoVision HD technology. You will see your magnified images in high definition while working with an ergonomic neck posture.
