If rural Canada is going to survive, thrive, and compete economically, the people and businesses in these communities need fast, reliable internet networks. Canadian Fiber Optics funds, designs, builds, and operates fiber networks to get Canada connected faster, with fiber technology and fewer government dollars.

At Canadian Fiber Optics, we believe rural Canada deserves equal access to the economic and social benefits of the internet. Unlike other companies, we focus only on connecting rural Canadian communities and enterprises with high-speed fiber networks.

If Canada is going to thrive, compete, and build back better, the people and businesses in rural communities need fast, reliable fiber internet networks.

Curvature of field in optical microscopy and how it is a common and annoying aberration that is familiar to most experienced microscopists is explained in this featured interactive tutorial.

Aberrations are divided into two main categories: errors that occur when polychromatic light (white light) is passed through a lens, and errors that are present when only a single wavelength (monochromatic) of light is utilized. The selected references listed in this section contain information about the cause and correction of the most common optical aberrations encountered with microscope and other lens systems. Bear in mind that the optical designer must correct for both polychromatic and monochromatic aberrations simultaneously in the production of well-corrected microscope objectives.

We collaborate with enterprise and community leaders to ensure any network we build will be financially viable, better residents’ lives, and boost the economy.

Aberrationsmeaning

Explore the relationship between astigmatism and comatic aberrations, and how astigmatism aberrations are manifested by the off-axis image of a specimen point appearing as a line or ellipse instead of a point.

Explore the two most prevalent types of distortion, positive and negative, and how they can often be present in very sharp images that are otherwise corrected for spherical, chromatic, comatic, and astigmatic aberrations.

Objectives are made with differing degrees of optical correction for both monochromatic (spherical, astigmatism, coma, distortion) and polychromatic aberrations, field size and flatness, transmission wavelengths, freedom from fluorescence, birefringence and other factors contributing to background noise. Depending upon the degree of correction, objectives are generally classified as achromats, fluorites, and apochromats, with a plan designation added to lenses with low curvature of field and distortion. This section addresses some of the more common optical aberrations that are commonly found (and often corrected) in microscope objectives.

Curvature of field in optical microscopy is an aberration that is familiar to most experienced microscopists. This artifact is the natural result of using lenses that have curved surfaces.

“High-speed internet is a need-to-have versus a nice-to-have for our residents and businesses, which is why we approved the broadband strategy and are investing up to $7.3 million for the pilot project area. Sturgeon County is very excited to be working with Canadian Fiber Optics to help fulfill Council’s vision for a connected community. Their experience with rural connectivity solutions and appreciation of the challenges faced by rural communities made them a clear front-runner for the Sturgeon County broadband project.”

Departures in lens action from the ideal conditions of optics are known as aberrations. Optical trains typically suffer from as many as five common aberrations: spherical, chromatic, curvature of field, comatic, and astigmatic.

An ideal microscope objective produces a symmetrical diffraction limited image of an Airy pattern from an infinitely small object point. The image plane is generally located at a fixed distance from the objective front lens in a medium of defined refractive index. Microscope objectives offered by the leading manufacturers have remarkably low degrees of aberrations and other imperfections, provided the appropriate objective is selected for the task and the objective is utilized properly in accordance with the manufacturer's recommendations. It should be emphasized that objective lenses are not made to be perfect from every standpoint, but are designed to meet certain specifications depending on their intended use, constraints on physical dimensions, and price ranges.
