How Much Does Lam Research 853-143791-912 Cost in 2026?

The 853-143791-912 Spectrometer Assembly with Excelitas PAX-1005-3LAM2 is priced at $699 (used) in 2026, with no refurbished units available due to its single-source sensor module. This represents 82–85% savings versus new units, which OEM lists at $3,883–$4,660. Caveat: Units with Excelitas sensors exceeding 5 years of operational age require recalibration at $125–$175, as photodiode sensitivity degrades by 3–5% annually beyond this threshold.
