Long working distance (LWD) microscope objective lenses from Microscope World.
The Long Working Distance Microscope Objectives are designed around 426 o 656 nm to provide a chromatic aberration-free image with a flat field correction. The objectives have a parfocal distance of 95 mm which means that the objectives are interchangeable within the turret of the microscope system with the same working distance to the specimen.
Working Distance and Parfocal Length Microscope objectives are generally designed with a short free working distance, which is defined as the distance from the front lens element of the objective to the closest surface of the coverslip when the specimen is in sharp focus.
Thorlabs offers Mitutoyo Plan Apochromat Objectives with 5X, 10X, 20X, or 100X magnification. These plan apochromat objectives feature chromatic correction at three wavelengths and spherical correction at two wavelengths to provide a flat field of view. The long working distance provides a wide spac
To adjust the objective working distance, translate the slider back and forth to change from regular working distance values through Extra Long and Super Long working distances (ELWD and SLWD, respectively) utilized on reflected light and inverted microscopes. Actual objective working distance values vary over a wide range, depending upon the ...
Dino-Lite Long Working Distance. For tasks where extra distance to the object and a larger field of view is required Dino-Lite offers a series of Long Working Distance microscopes. The extra working distance and larger field of view make this series an ideal solution for tasks such as repair, rework or assembly or for working with bulky objects ...
Mitutoyo’s objectives are world-renowned for setting the standard of excellence for long working distance microscope optics. They have achieved the best combination of working distance and optical performance by using a new approach—avoiding outdated conventions used by competitors.
Description. The Working Distance (WD) is the distance between the end of the Dino-Lite handheld microscope camera and object being viewed. There are Dino-Lite models from zero working distance (touching or close to touching at highest magnifications) and enhanced working distance models for those that require a little space between the microscope and subject and magnification up to 140x.
Microscope objectives offering both high NA and long working distance in addition to high transmission made possible by Nikon's exclusive Nano Crystal Coat technology. CFI Achromat Series A microscope objective with dramatically improved correction of chromatic aberration with performance similar to the CFI Plan Achromat Series.
Since its inception, the Model K2 has been the definitive world-standard state-of-the-art long-distance microscope, capable of resolution and magnification comparable to that of regular compound laboratory-type microscopes but at many times greater working distances.
