Abstract
1,128,080. Optical objectives. ASAHI KOGAKU KOGYO K.K. Sept.26, 1966, No. 42909/66. Heading G2J. An ultra-achromatic photographic objective of focal length F and power #, particularly for a wavelength range of 200 - 800 mÁ includes fluorite and fused silica lenses and consists of five air-spaced lenses wherein:- # 1 .... i being the resultant power of the first to the i<SP>th</SP> lenses. Optical data are given for the example shown wherein the positive lenses are of fluorite and the negative ones of fused silica.
