plan fluor vs plan achromat
Researchers sometimes require Apochromat for spherical color correction and higher numerical apertures, and a whole host of other reasons. 1) THREAD PATTERN: What is the thread pattern on your microscope? The main determining factors for choosing lenses includes the number of fluorescence colors you may want to detect, the quality of images required, and the working distance (distance between sample and the lens). The main determining factors for choosing lenses includes the number of fluorescence colors you may want to detect, the quality of images required, and the working distance (distance between sample and the lens). 40X Infinity Plan Achromatic Fluorescence Objective: Objective Optical System: Infinite: Objective Optical Magnification: 40X: Objective Type: Plan Achromatic Objective: Objective Parfocal Distance: 45mm: Objective for Focal Length: 180mm: Objective Working Distance: 0.35mm: Numerical Aperture (N.A.) Lomo 3.7x 0.11 Microscope Objective vs Nikon CFI Plan Fluor 4XA 4X/0.13 Microscope Objective vs . The image you see through a compound microscope is framed in a circle. You’ll need to make sure you have the correct thread size for your microscope when ordering an objective. Authorized Leica Dealer Thorlabs offers both air and oil-immersion designs of Olympus and Nikon visible imaging objectives. Plan Achromat Lenses are the mid-range quality lens and have been corrected to bring 2 wavelengths (red & blue) into focus on the same plane. Plan achromats provide flat-field corrections for achromat objectives (Figure 2). To avoid this, cancel and sign in to YouTube on your computer. If an objective is not labeled, it is achromatic. Achromatic lenses are corrected to bring two wavelengths into focus in the same plane – typically red (~0.590 µm) and blue (~0.495 µm). The main determining factors for choosing lenses includes the number of fluorescence colors you may want to detect, the quality of images required, and the working distance (distance between sample and the lens). The three objectives discussed above all produce a curved image. They have many different magnification powers and types such as plan achromat, plan fluor and planapo objectives lenses The difference from low power lenses are not obvious, which means that can be ignored. To restore the microscope system to the original condition (magnification and field of view), replace the 10X eyepieces with 20X eyepieces. Let WPI be your trusted partner as you stock your research laboratory with equipment, surgical instruments and supplies. These terms may help you determine the best objective for your application: Achromatic objectives–This objective brings red and blue light to a common focus, and is corrected for spherical aberrations for green. Browse our extensive lineup. ©Copyright 2021. This combination also affects the field of view. 863-644-3555 This is called infinity correction. A “Plan” objective maintains image flatness throughout image from center towards the outer edge. Achromat lenses are the basic quality lens and have been corrected to bring 2 … Nikon CFI Plan Fluor Objectives feature high transmission from the ultraviolet to the infrared, along with exceptional flatness across the entire field of view. The next level of correction is found in the ‘Plan-Achromatic’ objectives. Cancel. They will have the infinity sign on them (the sideways 8) or have /160 designating the 160mm tube length. Following on from achromatic lenses are the Plan-achromatic objectives (abbreviated ‘Achroplan’ or ‘Plan Achromat’). Common microscope objective lenses include achromatic, plan achromatic, Fluorite, plan fluorite, apochromatic and plan apochromatic lens. Most new microscopes are “infinity corrected” with a 200mm tube length. • APO, plan fluor and plan achromat objectives available • Rack and pinion focusing mechanism for smooth focusing control • Rackless, X/Y mechanical stage with adjustable tension • Modular design allows for flexibility in system configuration • Trinocular and ergonomic tilting trinocular head options • 10x/22mm eyepieces The use of these two options restores the visual field of view and magnification range back to the original condition with the added benefit of a larger working distance. Plan Achromat objectives standard, Plan Fluor (optional) Wide range of magnifications: 2X, 4X, 10X, 40X, 60X, 100X. The various wavelengths have different focal points. CCIS EF-N Plan Achromat objective 100X / 1.25 / S-Oil (WD=0.13mm) More Products by Motic. 3) Don’t confuse the focal length with the actual size of the objective.
