This method avoids many problems associated with other forms of lens "grinding." The process has been commercialized and could have a marked effect on the cost of implementing aspherics in eyepiece designs. Now I'm waiting for the distortionless, Plossl-sized eyepieces with 100 deg. fields for $200!! What about cheap objectives with above average quality? I don't know how large a lens it can be applied to. -Rich |
