In these devices lenses are occasionally paired up with curved mirrors to make a catadioptric method in which the lens's spherical aberration corrects the alternative aberration inside the mirror (for instance Schmidt and meniscus correctors).
(그것때문인지 아직까지 아큐브 모이스트를 사용하시는 분이 많은게 사실이라 생각되구요)
이상태로도 풀프레임에서 쓸만하지만, 조리개를 한두스탑 조여주면 광량저하가 개선되어 더욱 괜찮아진다.

Chromatic aberration is a result of the dispersion of the lens material—the variation of its refractive index, n, With all the wavelength of light. Given that, within the formulae above, file is dependent upon n, it follows that light of various wavelengths is concentrated to different positions. Chromatic aberration of the lens is found as fringes of colour throughout the impression. It may be minimised by making use of an achromatic doublet (or achromat) where two supplies with differing dispersion are bonded jointly to variety one lens.

The signs of the lens' radii of curvature show whether or not the corresponding surfaces are convex or concave. The indication convention utilized to stand for this varies[citation desired], but in the following paragraphs a good R implies a floor's Middle of curvature is even further alongside inside the way of the ray journey (appropriate, within the accompanying diagrams), whilst detrimental R signifies that rays reaching the floor have by now passed the middle of curvature.
