![]() Mounting thread: M26 x 0.706 pitch (36 TPI). ![]() All stated magnifications are based on a tube lens focal length of 200mm. For an infinity correction system, a secondary (or tube) lens is required. Optimized for bright field illumination (incident illumination parallel to optical axis), these lenses are ideal for in-line illumination applications. Plano Apochromats are typically very expensive, but high volume production has made it possible to keep the cost down to that of standard Achromat long working distance objectives. Infinity Super-Long Working Distance Plan Apochromatic Metallurgical Objective, Find Details and Price about Objectives Microscope Accessories from Infinity. An apochromatic objective lens is chromatic aberration corrected for red, blue, and yellow while a standard achromatic objective lens is only corrected for red and blue. These objective lenses are an M Plan Apochromatic design which offers a flat field correction, long working distances and superior optical performance. and contrast as possible, the lenses are all Plano Apochromats. ![]() Making the objectives larger and longer has made the designs easier (95mm parfocalization length). ![]() They have achieved the best combination of working distance and optical performance by using a new approach-avoiding outdated conventions used by competitors. Mitutoyo’s objectives are world-renowned for setting the standard of excellence for long working distance microscope optics. ![]()
