Notch filters (BEF, band inhibition) can transmission most wavelengths, but attenuates light to very low levels in a specific wavelength range (BEF). Notch filters, in contrast to band-pass filters, only inhibit light in a narrower wavelength range.

How to choose the doorway style
In today's world, with an ever-growing variety of curtain styles and designs, choosing the perfect pair can be quite a challenge for consumers. To help simplify the process, we've gathered some useful tips to guide you in selecting curtains that not only match your decor but also enhance your living space.
First, color selection plays a crucial role in setting the mood of a room. The right color can make a significant difference in how a space feels. For example, if your walls are a soft cream or white, adding light red curtains can create a luxurious and elegant atmosphere. If your walls are light yellow, brown curtains can bring warmth and comfort. In a child’s room with green walls, using green or yellow-toned curtains can add a playful touch. Additionally, consider the purpose of the room: wedding rooms should feature bright and vibrant colors to create excitement, while bedrooms for the elderly should have calm and soothing tones. Seasonal changes also influence color choices—lighter shades in summer and deeper tones in winter can affect the perception of temperature.
Next, the texture of the curtain fabric is equally important. Different materials offer unique benefits. Polyester-cotton blends are lightweight and elegant, ideal for cool-toned spaces. Linen curtains provide a natural, textured look with good drape. Knitted polyester offers a fresh and modern feel, while woven fabrics and velvet deliver a rich, sophisticated appearance. When it comes to thickness, thin curtains allow for soft, diffused light, while heavier materials like velvet are great for noise reduction. Many people now opt for a layered approach—using sheer curtains during the day and thicker ones at night—for added versatility.
Pattern selection should also align with the size of the window and the overall style of the room. Large patterns on small windows can make them appear smaller, while vertical patterns can create a more expansive feel. It’s important to avoid patterns that cause visual distortion, such as diagonal or twisted designs, which might make the window look slanted. For a modern, youthful bedroom, chic and stylish patterns work well, while traditional settings may benefit from simpler, classic designs like straight stripes or folk-inspired motifs.
Lastly, when it comes to pricing, curtain fabric varies greatly in cost depending on the store and quality. Prices range from around $20 to $300 per meter, and a full set for a house can vary by several thousand dollars. Therefore, it's wise to compare options across different stores and aim for the best quality within your budget.
By considering these factors, you can make a more informed decision and find curtains that truly enhance your home.
