The FL series refractors show remarkable improvement in chromatic aberration over d-ray(yellow), c-ray(red), F-ray(blue) and g-ray(purple) in comparison with an ordinary F15 achromatic refractor.The wave length of light transmitted by the Fluorite lens extends from 0.125 micron to 10 microns, which is twice as wide as the transmitting light of BK7 lens. The FL series refractors exhibit their power especially when you take photos of the faint objects, such as nebulae and clusters, and are also most suitable for observing planets at high powers.
