All Leica objectives are marked with codes and labels. These identify the objective, its most important optical performance properties, and the main applications it can be used for. For more information, refer to: Labeling of Objectives

Leica achromats are powerful objectives for standard applications in the visual spectral range, offering field flatness (OFN) up to 25 mm. The absolute value of the focus differences between red wavelength and blue wavelength (2 colors) is ≤ 2x depth of field of the objective.

Leica semi-apochromats are objectives for applications in the visual spectral range with higher specifications, offering field flatness up to 25 mm. The absolute values of the focus differences for the red wavelength and the blue wavelength to green wavelength (3 colors) are ≤ 2.5x depth of field of the objective.

Ocular lensmicroscope function

The objective lens of a microscope forms a magnified, real, intermediate image of the sample or specimen which is then magnified further by the eyepieces or oculars and observed by the user as a virtual image. When a camera is used to observe the sample, then a phototube lens is installed after the objective in addition to, or even in place of, the eyepieces. The phototube lens forms a real image of the sample onto the camera sensor. The objective’s numerical aperture (NA), its ability to gather light, largely determines the microscope’s resolution or resolving power to distinguish fine details of the sample. Also, the working distance, the distance between the sample and objective, and the depth of field, the depth of the space in the field of view within which the sample can be moved without noticeable loss of image sharpness, both greatly depend on the properties of the objective lens.

The Snell family’s dedication to providing an exceptional cinema experience has not gone unnoticed. As Snell’s middle brother works on opening a new theater in Enid, Oklahoma, the family envisions expanding their brand one location at a time.

Leica apochromats are objectives for applications with highest specifications in the visual range and beyond, offering field flatness up to 25 mm. The absolute values of the focus differences for the red wavelength and the blue wavelength to green wavelength (3 colors) are ≤ 1.0 x depth of field of the objective.

Tim started the Edmond Business online magazine in May 2020 to fill a need in the community when The Edmond Sun shut down and stopped publishing their monthly magazine, The Business Times.

Different family members run other locations. Snell explained, “My two older brothers opened their own personal theaters while I own the one in Edmond.”

For standard applications, Leica Microsystems offers an extensive range of top-class microscope objectives. There are also Leica objectives which have been optimized for special applications. The highest-performance Leica objectives feature maximum correction and optical efficiency and have won several awards. All over the world, scientists are relying on Leica microscope objectives to gain insights into their area of research.

Tim is a public speaker, author, publisher of Edmond Business, and the owner of Backslash Creative. He helps businesses that are worried they don’t have the expertise or time required to invest in doing their own digital marketing. He helps them plan where and how much to invest and often helps execute the plan.

By mid-2021, posters outside the theater let the public know about the new owner. The Icon Cinema poster hung next to pre-COVID movie posters, symbolically representing the location’s past and future.

Additionally, Icon Cinema offers a unique self-serve concession system, providing unlimited refills for popcorn, drinks, and ice in the lobby, enhancing the movie-watching experience.

Notably, Edwin Snell himself has embraced the Edmond community. He has relocated to the area and is actively involved in the theater’s day-to-day operations. “I even moved here myself and absolutely love the area. So it’s been a really nice reception from the community so far,” shared Snell.

In addition to the Edmond location, Icon Cinema has locations in Oklahoma City, Colorado Springs, Albuquerque, and San Angelo. They plan on opening additional locations as well.

After a wait of many months, the new Icon Cinema opened its doors earlier this year, replacing Kickingbird Cinemas near the corner of Danforth and Bryant. This family-owned theater has captured the attention of locals, providing a unique and welcoming movie-watching experience.

Leica microscope objective lenses are designed and made by our optics specialists to have the highest performance with a minimum of aberrations. The objectives help to deliver superior microscope image quality for many applications, such as life science and materials research, industrial quality control and failure analysis, and medical and surgical imaging.

Snell intended to purchase just the seating from the previous owners but ended up buying the whole building to start his own operation. Then in May of 2022, Icon Cinema opened in Edmond. Many residents were happy to see the location remain an independent and family-owned operation.

In March 2020, Kickingbird Cinemas closed down for the pandemic. Although Edmondites didn’t realize it at the time, they were never to open under the old ownership again.

What sets the theater apart is its commitment to creating a friendly and enjoyable environment for moviegoers. “We’re a night out at the movies,” Snell said.” You should be greeted at the door, welcomed in. Everything should be extremely clean.”

The optics of the most basic microscope includes an objective lens and ocular or eyepiece. The objective lens is closest to the sample, specimen, or object being observed with the microscope (see the schematic diagram below).

The first Icon Cinema opened in Roswell, New Mexico, 11 years ago. Since then, Edwin Snell has been running the theaters with his family.
