Reviews

Situated above the sensitive internal lenses of Bochu (BOCI) BLT cutting heads, this long-life second-upper protective window plays an important role in safeguarding critical optical components. At this position, exceptionally high fused silica purity and stringent anti-reflective (AR) coating standards are essential to minimise optical losses and help protect the lenses beneath from contamination.

Manufactured from high-purity fused silica with a premium AR coating, this precision optical window provides excellent laser transmission, low absorption and long-term durability. Designed for extended service rather than frequent replacement, it should only be changed when necessary and with exceptional care to preserve the cleanliness and integrity of the internal optics.
