UP FOR BIDS IS A NEW IN PACKAGE OPCO LAB ACROMATIC DOUBLET TELECENTRIC LENS 35mm FL x 18mm Dia, MgF2 Coating. SURPLUS ITEM FOR CCD CAMERA VISION INSPECTION SYSTEM FOR SPEEDLINE TECHNOLOGIES PART NUMBER P9704. PLEASE SEE THIS SITE FOR MORE INFO. http://opcolab.com/micro-optics/ An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus in the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as F2, which has relatively high dispersion, and the other is a positive (convex) element made of crown glass such as BK7, which has lower dispersion. The lens elements are mounted next to each other, often cemented together, and shaped so that the chromatic aberration of one is counter balanced by that of the other. In the most common type (shown), the positive power of the crown lens element is not quite equalled by the negative power of the flint lens element. Together they form a weak positive lens that will bring two different wavelengths of light to a common focus. A telecentric lens is a compound lens which has its entrance or exit pupil at infinity; in the prior case, this produces an orthographic view of the subject. This means that the chief rays (oblique rays which pass through the center of the aperture stop) are parallel to the optical axis in front of or behind the system, respectively. The simplest way to make a lens telecentric is to put the aperture stop at one of the lens's focal points. THANK YOU FOR VIEWING MY ITEMS, GOOD LUCK BIDDING.
