Performance
● Emented lens is an achromatic lens formed by splicing the low dispersion plus lens and minus lens. Different
dispersion values and lens shapes are optimized to minimize the chromatic aberration.
● Such lenses are allowed in the entire VIS region. The spherical aberration is also optimized in design. The
spherical aberration of achromatic double emented lens is much smaller than that of a single lens. When it is
used in the infinite conjugate state, the spherical aberration is the smallest.
