About this spectrum2 notes
Source & details
Source category: estimated
Estimated response: not a primary measurement (e.g. diffraction-grating closed-form recovery, model prediction). Independent of profile_type and quality/confidence grades.
Type: estimated
Estimated response, not a direct measurement; quality and confidence are assessed separately.
Quality: unassessed
Quality has not been assessed; no grade is inferred. Raster graph digitization; source measurement uncertainty is not documented.
Confidence: unassessed
Confidence has not been assessed; no confidence level is inferred. Exact chip and mode documented; complete camera equivalence is not established.

Methodology

As-is
Samples rendered verbatim: no smoothing, no interpolation, no zero-padding, no gap bridging in the browser. Documented null sparse cells render as visible gaps.
Uncertainty
Extraction tolerance is documented in the downloadable JSON; it does not quantify source measurement uncertainty.

Known limitations
  • A single monochrome trace changes display color with wavelength; those colors are not separate RGB channels.
  • The manual has inconsistent IMX455AQK-K/ALK-K part suffixes; the curve is associated with the explicitly monochrome camera and generic mono IMX455 family only, not a particular die suffix.
  • Camera AR window contribution is not separated. No data beyond 700 nm are supplied by this graph.
  • Digitized manufacturer reference for ZEUS 455M Pro. Other cameras using this sensor can have different filters and windows.
  • Exact-model QE graph; protective-window contribution is not separated.

Sensor information

Other cameras in the same sensor family (8)

Sensor-family links do not mean the complete cameras have identical spectral responses.

Source and sensor identification

Documented camera-to-sensor mapping from the official SBIG Aluma AC455 source. The source record establishes the listed camera model, sensor, and mode. Both linked records are sensor-scoped absolute-QE measurements, not full camera responses; keep them as separate source curves. This record does not claim a complete camera response or create a stock spectrum.

Player One ZEUS 455M Pro camera manual

Image area and resolution are documented for this reference camera; other cameras may use a different crop or binning mode.

Player One's manual prints IMX455AQK-K while other Sony documents distinguish the mono ALK-C and color ALK-K variants; the catalog identity stays at family level.
