aspherical mirrorの例文
- In this paper , we brought forward an innovative idea : according to the characteristics of easy deformation of ultra - thin mirror , we employ a sphere mirror , which is easier to fabricate and test , to replace the aspherical mirror , then the sphere mirror is deformed into an aspherical one by active optics technology . on this purpose , we need to study the mechanism and method of shaping a spherical mirror into an aspherical one
- The projection optics with aspherical mirror of sub - nanometer accuracy are required to get a resolution of less than 0 . 1 m m and wide exposure area simultaneously . the precision of polishing and testing for such ashperical surface is fairly high and it has not been achieved yet in our current state
