Thermo Scientific™ Olympus™ 40X Oil Objective, X-Apo, 1.40NA/0.13WD

Description

• This 40X apochromat objective is from the new Olympus X line with exceptional optical performance
• Through new manufacturing technology, the X-Apo objectives offer improved performance compared to standard Apo objectives in several critical areas: larger numerical aperture (NA), better image flatness, and a wider range of chromatic correction of 400–1,000 nm
• These objectives deliver superb brightness and resolution across a large field of view for applications where the best possible image quality is desired
• The Olympus objectives are compatible with all EVOS cell imaging systems
• Our wide selection of EVOS and Olympus objectives satisfies needs across the spectrum of magnifications and optical specifications
• Additional characteristics of this Olympus objective: Magnification: 40X Numerical Aperture: 1.40 Working Distance: 0.13 mm Immersion: oil Superb image quality Image quality Microscope objectives may be the most important components of a microscope because they are responsible for primary image formation
• High image quality is crucial to experimental success and often a requirement for publication; Olympus objectives afford that quality across the visible spectrum to near infrared light
• This performance results from years of lens manufacture experience, and the broad selection of objectives means that you can choose the optimal objective for your imaging requirements
• Objective classes Achromat objectives are perfect for general applications, with standard correction of color and focus
• Fluorite objectives deliver excellent resolution and are made with higher numerical apertures than achromat objectives, resulting in brighter fluorescence signal and higher contrast imaging
• The higher optical quality greatly reduces optical aberrations, and corrections for color and focus are at higher levels than achromat objectives
• Fluorite objectives are ideally suited for fluorescence and demanding transmitted light applications, where the higher contrast make them ideally suited for color imaging
• Apochromat objectives are manufactured to the highest levels of resolution, fluorescence brightness, and contrast; chromatic aberrations are almost eliminated
• They are recommended for the most demanding applications, particularly at magnifications of 60x and above
• Apochromatic objectives are the best choice for the capture of color images in white light
• Brightfield contrast versus phase contrast objectives Brightfield is the most basic form of light microscopy and is accomplished by sample absorption of light
• A higher density area in a sample will absorb more light, thus increasing contrast in those areas
• Phase contrast objectives are most useful for hard to see, translucent specimens
• This method of contrast is accomplished by converting phase shifts, caused by light passing through a translucent specimen, into brightness changes (i.e., contrast)
• Long working distance versus coverslip-corrected objectives Long working distance (LWD) objectives are optimized for use through vessels with a nominal wall thickness of 0.9-1.5 mm
• This includes vessels commonly used in cell culture and cell-based assays, such as slides, cell culture dishes and flasks, microtiter well plates, etc
• Coverslip-corrected objectives are optimized for use through #1.5 coverslips (thickness approximately 0.17 mm)
• These objectives have a higher magnification/NA ratio and provide higher resolution compared to LWD objectives.
