    Information and Notes

  • 1. Density filters are using CR coating to control the transimttance.
  • 2. Reduces the amount of light without affecting the color.
  • 3. The transmittance curves are based on actual measurements and may be different with manufacturing lots.
  • 4. Transmittance is a average value at 420 to 700nm.
  • 5. Browse below for more information and products,
