The thang-kng region of an accurate small area is left, and other regions on this face of triangular prism need to carry out sandblasting or frosted
Processing, because the thang-kng region and frosted regions on this face of triangular prism are in approximately the same plane, in triangular prism plated film
, it is necessary to protect triangular prism thang-kng region not to be grit blasted or frosted processing, otherwise by shadow when carrying out sandblasting or frosted processing afterwards
Ring the optical property in triangular prism thang-kng region.
It is usually first to connect a technique cover sheet in laminating in the region gluing of triangular prism thang-kng in the prior art, then
Sandblasting is carried out to triangular prism again or frosted is handled, technique cover sheet is removed again after sandblasting or frosted processing, will for precision
High optical element is sought, the positional precision and form accuracy in triangular prism thang-kng region require very high a, work in splicing
Need accurately to position bonding position during skill cover sheet, it is to avoid the triangular prism thang-kng regional location skew processed is led
Cause product unqualified, it is therefore desirable to design positioning precision height, protect reliable frosted processing positioning fixture.
