Single-sided anti-reflection glass and double-sided anti-reflection glass are the two main types of anti-reflection glass. Anti-reflective glass is widely used in construction, optical equipment, displays, museum display cases and other fields. Although both are anti-reflective glass, there are still differences in some aspects. Their differences are mainly reflected in the structure, manufacturing process, optical effect, application field.
Single-sided anti-reflective glass
Definition and structure
Single-sided anti-reflection glass is an anti-reflection treatment on one side of the glass. So that it can reduce the reflection of one side, the other side to maintain the characteristics of ordinary glass. Therefore, single-sided anti-reflective glass only needs to add one or more layers of anti-reflective coating on one side of the glass. In this way, the effect of single-sided anti-reflection can be achieved.
Manufacturing process
The production process of single-sided anti-reflection glass is relatively simple. Usually using sputtering or vacuum evaporation technology, the anti-reflective coating is attached to one side of the glass. The coating material can be silica, titanium oxide and other materials. According to customer needs, different materials can be selected to determine the optical effect. To achieve a good anti-reflection effect can be changed by adjusting the number of film layers and thickness.
Double-sided anti-reflection glass
Definition and structure
Double-sided anti-reflection glass is also easy to understand, that is, anti-reflection treatment is carried out on both sides of the glass. In this way, no matter at which Angle, any incident light can pass through the glass, and the reflective effect can always be kept low. It is covered with an anti-reflective coating, which can greatly reduce the reflection of the glass at different angles.
Manufacturing process
The production of double-sided anti-reflection glass requires a more sophisticated process. Usually one side is treated with an anti-reflective coating, and the other side is treated with the same treatment after drying. Both processes require precise control and need to ensure that the reflectivity of both sides is consistent. The precision of this production process is high, and the process is relatively complex, so the manufacturing cost is relatively high. Relatively speaking, the manufacture of single-sided anti-reflective glass will be more.
Comparative analysis of single-sided and double-sided anti-reflection glass
Optical effect
· Single-sided anti-reflection glass only has anti-reflection function on one side, while the other side will have the reflection effect of ordinary glass. Therefore, in terms of optical effects, single-sided anti-reflective glass is only suitable for the case of light incident from a single direction.
· Double-sided anti-reflection glass has anti-reflection function on both sides, which can comprehensively inhibit the reflective effect. At any incidence Angle, the double-sided anti-reflection glass can show good optical clarity and low reflectivity.
Application situation
· Single-sided anti-reflective glass is suitable for viewing only one side fixed display occasions, such as picture frames, display cabinets, electronic screens, etc.
· Double-sided anti-reflection glass because of the comprehensiveness of reflection, it is more suitable for multi-directional light or two-way visual occasions. Such as building curtain walls, display Windows and so on are its application areas.
cost
The cost of single-sided anti-reflection glass is necessarily lower than double-sided anti-reflection glass. The production process of double-sided anti-reflection glass is more complex, and the materials used are also more. Therefore, the cost of double-sided anti-reflection glass is higher.
