PEAK SILVER LUPE SERIES
We have added three kinds of epock-making silver lupes to Peak Lupe series so far supplied.
It is well known in Europe from several hundred years ago that the silver having purity of 92.5% is stable chemically and has a hardness best for use. We have used the sterling silver 925 to supply these splendid lupes.
Aster Lupe & Plain Lupe usage:
Keep the lens as close as possible to your eye. Then keep the object you observe away from the lenses and find where it is in focus.
Desk Lupe usage:
Place the Desk Lupe above the object you observe and find where it is in focus by up-down motion of your eye. Or use the Desk Lupe just like you use the Aster Lupe and Plain Lupe.
