Regarding the Dental loupes and Srugical Loupes. there are different style and different frames for the loupes. chich konds frames is aviable for? (1)Flip Up dental loupes surgical loupes Galilean loupes (2,5x 3.0x 3.5x ): the Ni-alloy frames ,sports frames and Titanium frames are all good choice. Sports frames and Titanium frames is lighter than Ni-alloy frames. Kepler (Prismatic loupes) 4.0x 5.0x 6.0x 7.0x 8.0x . the best choice is Headband style, becaue the Prismatic loupes is a little hearier than Galilean loupes. and another choice is N-alloy fraems or Titanium frames, sports frames is not aviable for the Kepler loupes . (2) TTL style loupes. As our experience, we suggest user choose the NEW TTL combines Flip Up Loupes, this style is new designing and called "new generation loupes". it is TTl style and with Flip Up Functions, and also can be mounted prescription lens. regarding the Normal TTL loupes, As our experience, the Ni-alloy frames and Titanium frames is good choice, though we supply the TTL with sports frames, but we don't suggest the clents choose this style. becaue the Normal TTL loupes design, need making a hole and glue the optics barrels on the lens. when wear the sports frames, the flex of temples of frames will be changed a little, this will be caused the loupes pupil distance chaged a little. so this is reason why we don't suggest chose the Normal TTL loupes wiht sporst frames. TTL combines Flip Up is new desing, and this problem will be not happened. because the lens is devided from the frames and temples. |
