NA is the Numerical Aperture. In most cases the material between the objective and sample is air, and “n” equals 1.00. For water, it’s refractive index is 1.33, and specialized immersion oil for microscopy is 1.52. For a low magnification objective such as a 4X or even a …

Now, attocube offers two versions of apochromatic objectives for low temperature operation. Whereas one version features high numerical apertures (NAs) of 0.81-0.82 within six color bands ranging from the UV to the IR, the other line of apochromatic objectives boosts the working distance to 5.0 mm while maintaining high NA of 0.63-0.65.

95mm parfocal distance for turret compatibility. The objective lens is the most complex and the most important component in a microscope. The multi-element design of these lenses works to produce the real image, which is then seen through the ocular lens. With Olympus’ range of microscope objective lenses, we provide outstanding optical performance from visible light to near infrared.

High-NA objective lenses are widely used in optical lithography, microscopy, etc. Consideration of the vectorial nature of light in the simulation of the focusing is therefore fundamental. VirtualLab Fusion supports both ray and field tracing analysis of such lenses with great ease.

Browse our extensive lineup. These objectives are ideal for use with UV lasers, such as 3rd and 4th harmonic Nd:YAG lasers. The rear conjugate of these UV fused silica objective lenses is corrected for infinity, ideal for interacting with collimated laser beams.

For example, a simple low-NA objective may contain a meniscus lens and an achromat. A high-NA objective typically contains a more complicated combination of various types of lenses of hemispherical, meniscus, achromatic doublet and triplet type. There are also reflective objectives, containing curved mirrors and no lenses.

In simple terms, the NA of a microscope objective is the ability of the lens to gather light at a fixed distance from the object on view. As light passes through … The NA of a microscope objective is important particularly concerning the following aspects: It determines how bright the observed image can be for a given illumination intensity. Obviously, a high-NA objective More importantly, the NA sets a limit to the obtained spatial resolution: the finest The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance. Image-forming light waves pass through the specimen and enter the objective in an inverted cone as illustrated in Figure 1 (a). 2021-03-20 2020-02-19 2020-07-04 The FLUAR objectives stand for maximum light transmission and photon collection. Manufactured from special glass, these objectives have been developed specifically for qualitative and quantitative analyses of ion modifications and for demanding fluorescence applications. Good flatness of field up to 23 mm, high numerical apertures and very high The objectives are labeled with their magnification, followed by the particular NA value, for instance 10x/0.40 or 63x/1.40.
