Product Details

Product Model: 61-6881-58
Product Brand: SIGMAKOKI CO., LTD.

Features

  • You can *** an ND filter that varies the optical density at equal intervals to cycle through the transmitted light levels.
  • Can be ***d for calibration of densitometers and colorimeters.
  • Beca*** 11 levels of evenly spaced optical density are arranged on a sheet of glass, a visual comparison can provide an approximate optical density value for an unknown optical density sample.
  • Since it is chrome coated, it can also be ***d to adjust the amount of light of the laser beam.
  • Since it is chrome coated, the optical density does not change even if the wavelength changes in the visible light range.
  • * The uniform transmittance range is 4.6×25 mm.
  • * Use with a beam of φ3mm or less.
  • * Transmittance varies logarithmically with the amount of movement.
  • * This is not a proportional relationship.
  • * Cannot be ***d for high energy pulsed laser.
