One of the most common applications of UV transmitting plexiglass is indoor tanning beds. In order to effectively tan skin, UV rays have to be absorbed by the skin. Traditional plexiglass does not allow enough UV rays through, although it is more than UV filtering plexiglass does. Other applications include:

Objective lenses are responsible for primary image formation, determining the quality of the image produced and controlling the total magnification and ...

Note: A laser interferometer is used for actual optical performance evaluations, thus providing evaluation with a single wavelength. Unless otherwise noted, Olympus offers Strehl ratio values measured with the e-line laser (544nm).

EKSMA Optics offers crystal quartz and achromatic retardation plates. Multiple order, low order or zero order wave plates are available.

UV Transmitting acrylic sheeting was designed specifically for indoor tanning applications as its properties allow for high UV light transmission, while retaining structural stability.

Although UV filtering acrylic is more popular than UV transmitting and has more applications, UV transmitting acrylic is important in places where the UV rays are required. With impeccable clarity, excellent weatherability, and high light transmission, this plastic has no additives to block the transmission of UV light. While UV filtering acrylic blocks up to 98% of UV rays, UV transmitting acrylic allows up to  92% UV ray transmission.

Assuming a convergence ratio in the image field of an aplanatic optical system (light intensity converging on an airy disc) as 100%, the convergence ratio in an optical system with an aberration is referred to as a "Strehl Ratio (SR)". As shown in the graph in Figure 2, an optical system with a higher SR value is closer to an aplanatic optical system.

Although the most common application of UV filtering acrylic plastic is for framing, this plexiglass is warranted for a variety of projects including:

UV filtering acrylic is one of the most popular specialized acrylic sheeting solutions on the market today. Although UV filtering plexiglass can not completely prevent colors from fading or darkening, it does filter out up to 98% of harmful UV light. This makes it the ideal plastic sheet material for protecting artwork, paper, or other keepsakes, that can turn yellow, fade, and become brittle.   It’s important to know that not all UV filtering plexiglass sheets are created equally, as some block more UV rays than others, and some even filter out harmful visible light rays. The UV protection of this acrylic sheeting only blocks UV wavelengths shorter than 400 nanometers. Visible light can also be harmful, especially in the lower violet range from 400-500 nanometers, and is blocked by certain kinds of UV filtering sheeting such as UF3 acrylic and museum grade acrylic.

Greenhouses are the second most common application of UV transmitting acrylic sheeting as plants see better growth due to high light transmission.   There are some things that both UV transmitting and UV filtering acrylic have in common:

Plastic sheeting with unique UV characteristics is often used where UV rays are an issue, whether it is UV filtering or transmitting. Applications that commonly see problems with traditional acrylic sheeting include display cases, museum lighting, animal habitats, tanning beds, and more. UV filtering acrylic sheet is used when UV light is not desired, and UV transmitting acrylic is used when UV light is required.

When a point light source is observed, an aplanatic optical system concentrates a light beam into one point at the image location. Contrarily, an optical system with aberration does not concentrate the beam into a point, resulting in a divergence. Figure 1 shows the appearances of a point image (intensity distribution of a point image) in both optical systems.

A Strehl ratio of 80% is commonly known as the diffraction limit. An objective lens below this limit is not assumed to have satisfactory performance. An objective lens with a Strehl ratio of more than 95% compares favorably with an aplanatic lens in performance for common observations.
