Working Distance and Parfocal Length.
. Our clients require a cost effective and compact solution for 18 mm ultra long working distance 100X objective. Optimized for brightfield illumination these objective lenses are ideal for in-line. For a long working distance microscope objective of more than 100X magnifications it is desired to satisfy condition 2.
The objective illustrated in Figure 1 is a 250x long working distance apochromat which. This lens is constituted of plural positive refracting force single lenses and constituted of a first lens group G1 converting a light beam. They have achieved the best combination of working distance and optical performance by using a new approachavoiding outdated conventions used by competitors.
Microscope objectives are perhaps the most important components of an optical microscope because they are responsible for primary image formation and play a central role in determining the quality of images that the microscope is capable of producing. Buy Aven 26700 400 L 4xlf Cyclops 4x Long Focus Lens Cyclops Lens Digital Microscope. In the case of objectives designed to be used without coverslips the.
PROBLEM TO BE SOLVED. Our objectives implement an innovative approach and plan-apochromat lenses that provide long working distance capabilities. At what magnification is the working distance greatest.
The LD C-APOCHROMAT objective has a long working distance while retaining a high numerical aperture of 11. Our newly developed ultra long working distance three points red blue and yellow achromatic design has high resolution of 011000 lpmm. The objective comprises a lens group A that comprises a positive meniscus lens concave toward an object side thereof and a plurality of cemented lenses has positive refractive power and converts light rays from an object to a.
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. For fine stitching of multiwindow wide-spectrum detectors an aspherical Schwarzschild objective with an effective working distance of 525 mm has been realized for chromatic aberration-free imaging in 400-900 nm wavelength range and with a numerical aperture of 013. Some objectives have a long working distance meaning that the objective can give you a good image over a large range of coverglass.
All objectives have flat image surface over 42mm field of view highest standard in the objective design. A circular polarizing plate and depolarizer are built into T Plan EPI 125. The current market is limited to working distance 12mm for 100X microscope objectives.
It is particularly suited to fulfill your demands in confocal multiphoton microscopy which extremely high penetration depths are achieved through the use of infrared excitation light. The invention provides a microscope objective having a working distance longer than achieved so far in the prior art even at more than 100 magnifications. Mitutoyo infinity corrected microscope objective lenses have set the standard of excellence for long working distance microscope optics.
However in contrast to a traditional Linnik microscope the new microscope does not rely on the use of matched objectives in the sample and the reference arms of. A microscope objective is composed of a complex set of lenses and optics and different objectives are designed for different imaging tasks. Time-saving acquisition superb LED illumination high-resolution camera for ace images.
Working distance is the distance between the front of the microscope objective lens and the surface of the specimen or slide coverslip at the point where the specimen is completely in focus. The objective is infinity corrected and comes with a M26 x 36 TPI threading. Newly developed objectives evolving the recognized high NA and long working distance CFI60.
Capturing good images relies on choosing the correct objective. An objective having a long working distance comprising in order from an object. Any deviation from the range given by condition 2 causes a deviation from the aplanatic condition resulting in increases in coma and.
A theoretical approach for analy. Thanks to its advanced optical design including an aspherical element and optimized coatings that minimize. Mitutoyos objectives are world-renowned for setting the standard of excellence for long working distance microscope optics.
The design of the new microscope is similar to that of a Linnik interference microscope and thus preserves the full working distance of the long-working-distance objectives utilized. Buy 4X Infinity-Corrected Achromatic Microscope Objective Lens Working Distance 1231mm from View Solutions Inc. HOLMARC developed super long working distance microscope objective for high image quality inspection and analysis application.
Motic microscope long working distance objectives. As a general rule working distance decreases and total magnification increases due to the higher numerical apertures associated with high power objectives. To obtain a long working distance microscope objective lens having intermediate magnification and excellent image formation performance while having a long working distance longer than heretofore.
Long working distance objectives enable users to have more room in their specimen holding area to easier manipulate samples or work. Employing Nikons unique phase Fresnel lens the CFI60-2 Objectives realize highly corrected chromatic aberration sharp and clear image and long working distance. The MLWD-50X Long Working Distance Microscope Objective Lens has a 50x magnification 055 numerical aperture and 4 mm focal length.
