A UV blocking filter or ultraviolet optical filter prevents ultraviolet light transmission. UV filters are commonly used in photography to reduce the level of ultraviolet light that strikes the recording medium.
Optical filters are a great tool for a wide variety of lighting applications. One common use of optical filters includes changing the correlated color temperature of a light source. The class of optical filters used to make these types of color changes are called Color Temperature filters. This article discusses the use of Color Temperature Orange (CTO) And Color Temperature Blue (CTB) filters in particular.
A bus bar is a strip of conductive material applied to the surface of a conductively coated glass, most commonly ITO (indium tin oxide) or IMITO (index matched ITO) coatings. Bus bars are screen printed onto an exposed surface of the coated glass; Abrisa applies bus bars either by thin film deposition of chrome-nickel-gold or by screen printing.
A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the color(s) of light that they reflect, rather than the color(s) they pass.
Oleophobic coatings are well-suited for projected capacitive (PCAP) and capacitive touch screens, handheld devices, teleprompters, virtual reality applications, and more. Hydrophobic coatings do not allow water to bond with the surface of the glass. This article further discusses the differences between oleophobic and hydrophobic glass coatings.
Non-glare glass is manufactured by acid etching one or two surfaces of the glass, providing uniform evenly diffused surfaces for high resolution applications. AR glass is a glass that has been optically coated on one or two sides to diminish reflections and increase the light transmission, to reduce surface glare and increase substrate transmission and brightness offering better contrast definition by reducing surface reflection over a specific wavelength range. This article further discusses the differences between these two glasses.
A neutral density, or ND, optical filter reduces or modifies the intensity of all wavelengths or colors of light equally, therefore providing for no changes in the hue of the color rendition. Neutral density filters can be colorless or clear, or they can be grey in tone.
Heat Absorbing Float Glass (HAFG) is designed with the capability to typically absorb 40% of the infrared (IR) light and about 25% or more of the visible light that passes through it.
Abrisa Technologies can deposit a wide variety of precious and non-precious metals onto glass substrates depending upon the application requirement. Metal mirror coatings are often used in systems where a very broadband reflector or beam splitter is needed.
Generally used for architectural projects, entertainment lighting and landscape lighting, the soda-lime or borofloat based glass can be heat strengthened for additional resistance to thermal shock. The glass can be machined, screen printed, sandblasted and fabricated to virtually any shape or size.
