What Is A UV Filter?
11/21/2019
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 – Color Temperature Orange (CTO) And Color Temperature Blue (CTB)
11/21/2019
The class of optical filters used to change the correlated color temperature of a light source is called Color Temperature filters. This article discusses the use of Color Temperature Orange (CTO) And Color Temperature Blue (CTB) filters in particular.

Bus Bars And Optics
11/21/2019
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. Abrisa applies bus bars either by thin film deposition of chrome-nickel-gold or by screen printing.

What Is A Dichroic Filter?
11/21/2019
A dichroic filter, thin-film filter, or interference filter, is a color filter used to selectively pass light of a small range of colors while reflecting other colors. 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 vs. Hydrophobic Glass Coatings
11/21/2019
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.

Anti-Glare vs. Anti-Reflective Glass
11/21/2019
Non-glare glass is manufactured by acid etching one or two surfaces of the glass; AR glass 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.

What Is A Neutral Density Filter?
11/21/2019
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.

What Is Heat Absorbing Float Glass?
11/21/2019
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.

Introducing Metallic Mirror Coatings
11/21/2019
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.
