Quality of Optics the best method to evaluate loupes' optic quality is to look at an object with straight black lines. The most common signs of poor quality optics are low resolution as shown in figure A. Higher quality optics will have lines that appear straight and clear, as shown in figure C.

Quality of Frame can be determined by looking at the material of the frame and tightness of all the components.

Magnification requirements are determined by the type of tasks you perform while wearing your loupes. If you are dental hygienist, you might only need a 2.5x magnification loupe system. But if you perform surgical tasks like root canal procedures, then you may need a loupe system of 4.0x magnification or more.

Light Transmission is important not only for quality of the image but also for the comfort and safety of your patients. Optimized light transmission means that you can work with less light thus reducing your eyestrain while minimizing the exposure of your patient to bright light.

Depth of Field is defined as the range of distance that is in focus without moving your head. The ergonomic benefits of a large depth of field are clear because there is less need to move your back, neck and head to work effectively.

Field of View refers to the amount of the original object that you can see from left to right and top to bottom. Different applications have different needs. A larger field of view is not always the best choice. For example, an endodontist might prefer to see only the small area being treated, whereas a periodontist might like to see as much of the surrounding area as possible.

Working Distance requirements vary by the user's height and body type, and also by how you sit or stand while work with your patients. The best method of determining your working distance is to measure the distance from your eyes and the patient’s teeth, while sitting or standing in an ergonomic position at your normal workspace.

TTL vs Flip Up
TTL stands for "Through The Lens". It means the loupe optics are glued to the lens. Although TTL is slightly lighter than Flip-Up systems, it can not be moved from the line of vision and the user can not make adjustments to the angle of declination to accommodate for the patient's position. Each pair of TTL loupes are custom made, so they are more expensive than the Flip-Up loupes.

Comfort of Use is determined by the weight of the whole system and the ergonomic design of the frame. Our frames are made from titanium, one of the lightest and toughest material used for high end glasses, that ensures the ultimate comfort for long periods of usage.
