Infrared 12-LED flashlight pointed into DSK (pulled out just at edge of "clipping" of highest band). LEDs emit visible deep red (which can be blocked by a typical IR-rejecting filter). Brand unknown (flashlight case is slight bluish silver in color). This appears to be the same model.-- (Cloned calibration from calib1)

Operation Date Description

Operations enable reversible modification of data -- they act like filters which process the data. The graph you see above represents the data after these operations have been run. Delete them to undo their effects, or to apply them in a new order.

  • The thumbtack symbol indicates that data has been saved in a snapshot upon running that operation.
  • The symbol indicates that the operation's data snapshot is being referred to by another operation. Click it to learn more.
  • Operations with a #000-style suffix, like subtract:3243#2414 are referring to a specific snapshot (in this example, #2414) of another spectrum. Click to learn more.

Device apparently claims to be 850nm, this is not wrong but we see here that its max band is 838-852nm, with another crest between 596-619nm, which probably accounts for the "deep red" color visible to the eye.
