The slumping of optical surfaces during coating.
Slumping of optical surfaces takes place while antireflection substrates are being coated at 205 degrees C. Greater slumping is experienced at higher temperatures. Optical glasses held in kinetic-designed holders exhibit variable memories of reslumping. Glass elements held in nonkinetic and kinetic holders are compared at 205 degrees C.
