Optical Dicing Calculator
Calculate filter yield from a square wafer with blade and margin constraints.
Wafer Size (mm):
80 x 80 mm
60 x 60 mm
100 x 100 mm
Custom
Choose a preset square wafer size, or pick Custom to enter your own value.
Custom Wafer Size (square, mm)
This sets both wafer width and height.
Filter Shape:
Rectangle
Round
Select the geometry of each filter piece.
Filter Size (mm):
Use preset sizes or choose Custom to manually enter dimensions.
X (mm)
Rectangle width in millimeters.
Y (mm)
Rectangle height in millimeters.
Diameter (mm)
Round filter optical diameter in millimeters.
Process Preset:
Default (Blade 2.0 mm, Margin 5.0 mm)
Optimized (Blade 0.5 mm, Margin 2.0 mm)
Custom (manual blade + margin)
Preset applies both blade width and wafer margin values.
Blade Width (mm):
Kerf width removed by each blade cut.
Margin (mm):
Safety edge excluded from the wafer boundary.
Note: Real-life yield is not 100%. Different coating designs can produce very different actual yields.
