How do you know your coating is working as advertised?

• Light Losses (if coating working properly)

  • No Coating ~ 4% lost/surface
  • Fully Coated ~2% lost/surface
  • Multicoated ~ 1.5% lost/surface
  • Fully Multicoated ~ <=1% lost/surface

• ¼ of 550 nm is 0.000000137 meters or 1370 angstroms. One MgF2 molecule is ~2.5 Angstroms.... coating should be 550 molecules thick.

• If the coating is twice as thick, the waves will reinforce, not cancel. The thickness is critical!!!!
