HOMEExamination Instruments
We develop and manufacture various medical diagnostic equipments and supply them for domestic and overseas markets.
The sight tester (L-7040) can measure visual function and refractive errors in the most normal condition with bright and wide fields of vision.
A universal trial frame light weight type (K-0547) keeps patients in comfort during the long duration of the test.
Along with their basic functions, all of our examination instruments incorporate our original ideas for the sake of convenient use by opticians, medical doctors and patients.
