Product Details

Ultra-Thin Flexible Optical Glass Slotted Windows

Groove parameters can be precision-designed and fabricated to match specific application requirements, delivering functions including optical path guidance, beam limiting and polarization control. These components are widely deployed in optical fiber communication systems, especially inside fiber couplers, to achieve accurate fiber alignment and boost coupling efficiency.

1. Structural features：

Slots are fabricated on optical windows (round, square and other profiles) via cutting, milling or etching processes. Slots can be through-cut (fully penetrating) or blind slots (partial depth only).

2. Common slot shapes:

(1) Straight grooves: single or multiple parallel grooves (e.g. linear bar grooves).

(2) Cross grooves: orthogonal double grooves creating four-quadrant segmentation.

(3) Circular grooves: concentric or eccentric circular recesses.

(4) Custom shaped slots: made to order, such as L-shaped and curved profiles.

3. Material selection：

(1) Substrates share the same material options as conventional optical windows and must satisfy defined optical performance specifications.

(2) UV-Vis range: fused silica (UVFS), calcium fluoride (CaF₂).

(3) Infrared range: zinc selenide (ZnSe), zinc sulfide (ZnS).

(4) General visible applications: N-BK7 glass, borosilicate glass.
