All models come standard with Infinity Corrected Optical objectives (F=200) delivers bright, clear, high resolution images with superior contrast.
Viewing heads are supplied with a Siedentopf type binocular head, inclined at 30Deg or a trinocular Siedentopf head inclined at 45Deg. Interpupillary distance is adjustable from 53mm to 75mm. A graduated diopter adjustment is provided as a standard feature on the left eyetube of all units.
Eyepieces are widefield, high eye point eyepieces, with a 25mm reticle mount, and focusing eyepieces are available as an option. Anti-reflection coated, manufactured with a large diameter lens with more optical elements and high eyepoint to reduce eye fatigue and accommodate eyeglass wearers, and come equipped with a fold-down rubber eye-guards. The newly designed eyepieces allow for a wide field of view observation, making it possible to see the whole image of an embedded resin sample.
Infinity Corrected Plan. Semi Apo BD 5X, 10X, 20X and LWD 50X objectives are standard in all units. Objectives are made with extra-low-dispersion glass and utilize new advanced multilayer anti-reflection coatings. The advanced technology used in designing and creating objectives result in an objective with a higher resolving power, higher image contrast, wider field of view, improved flatness of field, and a sharp image with a minimum of flare and ghosting. The objectives are color corrected for chromatic aberration in the red and blue regions of the spectrum and offer and exceptional flat field of view.
