Specification Notes:
- Standard working distance is 5 mm for all ILW and ILH.
- Diameter tolerance is +0/-0.05 mm for all ILW and ILH.
- Resolution is measured on a U.S. Air Force chart while a 100X microscope is focused on the back surface of the imaging lens (see Figure). The chart is placed at 5 mm, the standard working distance, away from the lens. Resolution is measured at both lens center and 80% of the lens radius and normalized by the magnification factor.
- Field curvature is the difference in focal positions between the lens center and at 80% of the lens radius.
- End surface is inspected at 20X magnification. No chips and cracks are allowed within 90% of the lens radius.
- Material Toxicity: This product contains components which might be toxic. The user is advised to pay special attention to such toxicity when using this product in medical devices for people or animals.
- Storage and Handling.
