In the right column of Tables C and D, the values were obtained by measuring the same sample supported on a standard white background. High Gloss sheets in clear are highly transparent and colourless, allowing the most light through of any of our products at 92% light transmission. In addition, it is also shatter-resistant. Therefore, the 1/4” thick sheet transmits less light than the 1/8” inch thick sheet. Its source may be the sun, infrared heating elements or any hot object. 0.118” (3.0 mm) 0.177” (4.5 mm) 0.236” (6.0 mm) 86%. Edges should be highly polished to maximize light transmission. Ultimately, the color of the sheet results from the combination of transmitted and reflected light that the human eye receives from the sheet. See Table E below and Table F on to the right for a sampling of standard colors. Perspex® Opal Sheet. This broad range of flexible Tygon® tubing products are engineered to meet many user specifications including chemical resistance, fluctuations in temperature, abrasion, high purity and long service life.

White translucent cast and extruded ACRYLITE® sheet are available in different densities to provide a variety of options for light transmission, diffusion, lamp hiding power and surface brightness. Our acrylic sheets offer exceptional light transmission enhanced by LED lighting. Visible hot spots and luminance fluctuations are eliminated without affecting the light transmission properties. Colorless ACRYLITE® cast and premium sheet have very small amounts of light transmission below 345 nm. Each type of infrared radiation is characterized by a specific range of wavelengths. These thermoplastic panels are often used as a lightweight alternative to glass and other materials because they offer excellent optical quality, high light transmission… ASTARIGLAS® GP. Acrylic is having the best light technical characteristics. Acrylic is produced in two basic variations, cast and extruded. The information is provided by You have no items in your cart. Ultraviolet, visible, and infrared light can also be produced by artificial sources. It serves a multitude of applications from framing pictures to artistic use to light dispersion and even aerospace. Light reflectance is also important in sign applications. Therefore, its transmission characteristics can be predictably modified using dyes and pigments to create a variety of colored sheet. Some elements may not work properly. exclusive 10-year limited warranty on light transmission – your assurance of a quality product. Energy in the visible band is sensed as “light” due to the sensitivity of the human retina, which acts as a detector for energy at this wavelength. If light rays strike the sheet at angles greater than 30° from the vertical, the surface reflectance will be greater than 4% and the overall transmission will be smaller. Long wave radiation is emitted by the mass, such as soil or concrete, inside a greenhouse. Otherwise, the sign will look gray during the day when it isn’t illuminated from behind. This color is ideal for use in applications where it is desirable to conceal infrared security cameras or infrared transmitters and receivers. • Optical Clarity - 92% light transmission makes it clearer than glass. Cleaning & Industrial U.S. and get all the latest news, trends and offers straight to your inbox. 31% Light Transmission White Acrylic Sheet. The UV spectrum is commonly divided into three ranges: Wavelengths in the UV-A range are responsible for tanning and pigmentation of the human skin. Select a white color that not only transmits a high percentage of light, but also reflects a sufficient amount of daylight. Roto-molded LLDPE with thick walls for superior strength and durability. In the 1400 – 2200 nm range, ACRYLITE® cast and premium sheet transmit radiation at a gradually decreasing rate; at 2200 nm, transmission approaches zero. This helps to eliminate bright spots caused by the light source. Reflectance data is shown in Table C and D. When ACRYLITE® cast or premium sheet is used for a non-back-lit sign panel, a nearly opaque white such ACRYLITE® premium sheet color WT030 GT having a light reflectance value of 91% will provide good contrast for painted or fabricated letters that may appear on the sign.

UV-C radiation is absorbed in the ozone layer and never reaches the earth’s surface. We carry carry hose barb fittings in a variety of materials suitable for all sorts of applications. Therefore, it is very important to evaluate colors under the intended end use conditions. Transparent colors offer light transmission through the material enabling it to act as a colored or tinted window. The superior quality of light diffusing acrylic sheet diffuses the light source to reduce hot spots, while dramatically increasing light transmission compared to normal sign white plastic sheeting. Acrylic is easy to work with, can be sawed, drilled, painted, decorated, glued, and formed. Acrylics have outstanding resistance to long-term exposure to sunlight and weathering. Perspex cast acrylic has been made in the UK since 1933 and trademarked in 1934. The visible band of the electromagnetic spectrum, which is the only range that can be detected by the human eye, falls between 400 and 700 nano-meters (nm). Light transmission depends on the reflectance at both surfaces of the material and the absorption of light into the material. Acrylic plastics have proven themselves over the past 35 years as a weather-resistant, maintenance-free skylight glazing material. The approximate relative distribution of solar energy (mean noon sea level sunlight) from 200 to 2200 nm is represented in Graph 2 above. Some colors are quite similar in appearance under reflected light but transmit light at different rates. You'll save money buying light diffusing acrylic over frosted glass at the initial purchase price and during shipping, handling, and fabrication. Cast sheets good for use in laser cutters. Examples of other types of electromagnetic radiation are ultraviolet light, x-rays, radio waves, and infrared light (Graph 1). This site requires JavaScript to function. Unlike matt Emco offers many different lighting panels for your every need. On either side of the visible light band are ranges of similar electromagnetic radiation undetectable by the human eye. They have strong reinforcing ribs for strength and a space-saving, tapered design allows pails to nest. X COVID-19 Safety ...

Non-Glare Acrylic Sheet. … The values shown in the left column in Tables C and D were obtained by measuring samples supported on black background material. Shown below in Graph 5 are the transmission curves for several amber colors having good UV absorption characteristics. For additional versatility, colored film or sheet can be placed behind ACRYLITE® LED color changing back lit, to alter the color of the sign when back lit. This section of the electromagnetic spectrum can be divided into three components: Nanometers (nm) are commonly used for measuring wavelengths in the three bands listed above. Since the ratio of transmitted to reflected light and the nature of the light source can vary based on application parameters, the perceived color of a sheet can also vary with these parameters. Break resistant yet easy to cut-to-size, acrylic lighting panels reduce glare, provide pinpoint brightness and enhance visual comfort. Therefore, its transmission characteristics can be predictably modified using dyes and pigments to create a variety of colored sheet. When a backlit sign must be as effective during the day as at night, a compromise is in order. Wavelengths in the UV-B range cause the most photochemical degradation in plastics as well as sunburn. Therefore, the starting point for the selection of material is always to choose acrylic. This is accomplished by adjusting the colorant concentration according to sheet thickness. 35% light transmission. The clarity and light stability of acrylic resin make it possible to manufacture crystal clear ACRYLITE FF sheet.

Fluorescent lamps, mercury vapor lamps, germicidal lamps and welding arcs produce significant ultraviolet radiation. Although ultraviolet (UV) radiation amounts to only 3% of the total radiation that reaches the earth, it is energetic enough to cause chemical reactions, weathering of polymers, fading of certain dyes, and even eye damage. We are primarily interested in the near infrared range (NIR) from 700 to approximately 10,000 nm. The range of light transmission through the opal sheet, up to 70%, receives maximum haze and subsequently offers the maximum light … Acrylite FF sheet is available as a colorless plastic as well as in a standard transparent and opaque colors. The transmission characteristics are like those of flesh; therefore these materials can be used in medical as well as industrial applications where x-ray transmission is required.
