Tracked international express. Delivery terms: DAP (Delivered At Place). The buyer is responsible for import duties, VAT/GST and any customs brokerage charges in the destination country.
Each shipment includes the spectral / test data for the supplied batch.
The curve shown is typical measured transmission (T) from our manufacturer data, redrawn; it is not a reflection measurement. Reflection is specified as R 99% at 785 nm. The lot-specific test report supplied with each order is the reference for the batch you receive.
Angle-of-incidence data is available on request — include your intended AOI when you request a quote.
Size is 25.2 × 35.6 × 1 mm. Confirm fit in your holder or Raman head against your current part’s drawing.
If your instrument, method or purchasing rules call for a specific brand part number, keep using that part. Brand parts publish their own datasheets — check the brand’s current datasheet for the latest values.
