Abstract

At the primary focus of JNLT, three-lens correctors with two aspheric surfaces will be used. They are designed for the wavelength region of 320-500 nm and 440-1100 nm, respectively, and provide images of less than 0.2 arcsec rms radius for a field of 30 arcmin diameter. The corrector for the blue region will include an atmospheric dispersion corrector. Characteristics of aberrations that arises in JNLT primary corrector are discussed.
