Available Lower Protective Lens Sizes
This collection covers BOCHU BOCI lower protective lenses, also called lower protective windows, for the lower protective position in BLT fiber laser cutting heads. Available size families include D25.4×4, D34×5, D37×7 and D50×8. Each family may have different part numbers and BLT model mappings.
How to Select the Correct Lower Protective Lens
Start with the lower installation position, then match the exact dimensions, BOCHU part number and compatible BLT model shown on the product page. Similar diameter or appearance does not establish compatibility. Use listed power information only as an additional configuration cross-check. If uncertain, send a photo of the existing package, label or cutting-head nameplate for confirmation.
