What is the 700nm IR acrylic longpass filter?
The 700nm IR acrylic longpass filter, an optical component crafted from acrylic (PMMA), transmits infrared light above approximately 700nm and blocks visible light.
What’s the advantage to use the 700nm IR acrylic longpass filter?
Compared with coating type IR longpass filter or HWB color filter glass, there are several advantages to use the IR acrylic longpass filters.
- Lightweight and Durable: Acrylic is impact-resistant and weighs about half as much as glass, making it a safer and lighter alternative for inspection windows and protective enclosures.
- Cost-Effective and Easy to Process: PMMA offers excellent transparency which approximately 90% and is easier to machine and mold than glass, making it ideal for mass production, general purpose applications. It can be cut into any shape and is available in various thicknesses.
- Good Weatherability: It has strong adaptability to natural environments, with good anti aging performance for outdoor use.
