What to check before ordering

  • 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.

Reference / cross-reference

  • Closest published Chroma part for reference: RT785rdc

Chroma RT785rdc is 25.5 × 36 × 1 mm; DX-DI785R-25x36 is 25.2 × 35.6 × 1 mm — confirm fit in your holder. Our measured edge is ≈ 798 nm (50% T); AOI data is on request. Brand specifications are quoted from their public product pages as published at the time of writing — check the brand’s current datasheet for the latest values.

See the brand part reference table for the full list of published differences. “Closest part” means the nearest published part by wavelength and function; it does not imply identical performance.
