Yellow polarizer is an optical component used in 3D printer screens to optimize display quality and light transmission efficiency. It is made by dyeing a polyvinyl alcohol (PVA) film with highly dichroic yellow or orange dyes. The polarizer selectively absorbs and polarizes ultraviolet light, improving the polarization degree and transmittance of light. Its structure includes a middle PVA film layer and protective layers, such as triacetic acid cellulose ester (TAC).
Overview of Yellow Polarizer Film in 3D Printer ScreensYellow polarizer is an optical component used in the screens of 3D printers, primarily made by dyeing a polyvinyl alcohol (PVA) film with highly dichroic yellow or orange direct dyes. Its main function is to selectively absorb and polarize ultraviolet light, improving the polarization degree and transmittance of light, thereby optimizing the display quality and light transmission efficiency of 3D printer screens.
The structure of a yellow polarizer typically includes a middle PVA film layer and upper and lower protective layers (such as triacetic acid cellulose ester TAC). The PVA film is stretched and dyed to form a straight-chain state, which can effectively absorb light in the 350-500 nm wavelength range, meeting the high polarization degree requirements for ultraviolet light in 3D printing.
Advantages of Yellow Polarizer Film1. High Polarization Degree: Yellow polarizer has a high polarization degree for ultraviolet light (greater than 99.5%), effectively filtering out stray light and improving the display quality of 3D printer screens.
2. Resistance to Ultraviolet Light: Due to the use of highly dichroic dyes, yellow polarizer is highly stable under ultraviolet light exposure, with minimal loss or deactivation, maintaining high polarization degree over the long term.
3. High Transmittance: In the violet light band (e.g., 405 nm), yellow polarizer has high transmittance, improving light transmission efficiency and reducing printing time.
4. Cost-Effective: Compared to traditional iodine-based polarizers, yellow polarizer has a lower manufacturing cost while meeting the high polarization degree and ultraviolet resistance requirements for 3D printing.
5. Adaptability to High Temperature and Humidity: Yellow polarizer performs well in high temperature and humidity conditions, with minimal failure risk.
6. Simple Structure: The manufacturing process of yellow polarizer is relatively simple, making it suitable for mass production.
In summary, yellow polarizer offers significant optical performance and environmental adaptability in 3D printer screens, making it an ideal polarizer material.
