Filter shielding glassIt is a type of glass with excellent transparency that can block specific wavelengths of light such as ultraviolet or infrared, also known as optical filter glass. It is mainly composed of a glass substrate and a specific optical filter coating. Filter shielding glass selectively transmits or reflects unwanted light through a specially designed optical filter layer, thereby protecting vision, adjusting light, preventing ultraviolet rays, filtering infrared rays, and other functions.
The main characteristics of filter shielding glass include:
1. High transmittance: Filter shielding glass achieves optical properties such as high transmittance, low reflectivity, and low light leakage, making light almost distortion free when passing through the glass. Therefore, when examining the target, it can be ensured that the observed image is very clear.
2. Anti light and UV protection: Filter shielding glass can selectively filter harmful UV or infrared light by adjusting the optical properties of the glass, playing a role in shielding light and other frequency interference signals.
3. Automatic brightness adjustment: The filter shielding glass can automatically adjust the brightness according to changes in natural light, avoiding visual fatigue caused by too strong or too dark natural light.
4. Waterproof, corrosion-resistant, and scratch resistant: Filter shielding glass has certain waterproof, corrosion-resistant, and scratch resistant properties, which can resist some external damage.
Filter shielding glass is mainly used in the following fields:
1. Military and police fields: Widely used in shooting, missile guidance, eyepieces, night vision devices and other equipment in military and police fields, it can protect the user's eyes and the optical system of the instrument.
2. Industrial field: Widely used in industrial equipment, laboratory instruments, infrared analyzers, laser systems, spectral analyzers, etc., it can protect environmental light and optimize display.
3. In the civilian field, it can be applied to cameras, car displays, aviation instruments, medical instruments, and so on.
In short, filter shielding glass is an excellent filter material that can be used in different fields to improve the visual effect of target objects, while also bringing better protection and safety.
