Infinity mirrors create a stunning visual effect that appears to stretch light into endless depth, making them a popular choice for art installations, home décor, and high-end retail displays. This optical illusion is achieved using a combination of Silver Mirror Acrylic, and See-Thru / Two-Way Mirror Acrylic, which work together to create the perception of an infinite tunnel of lights. But how exactly does an infinity mirror work? In this guide, we’ll explore the science, materials, and construction process behind this fascinating effect.
What is an Infinity Mirror?
An infinity mirror is a specially designed reflective system that creates the illusion of a tunnel of infinite light reflections. This mesmerizing effect is achieved by strategically placing two mirrors parallel to each other—one being a fully reflective Silver Mirror or Mirror Acrylic, and the other being a See-Thru / Two-Way Mirror Acrylic. Between these mirrors, LED lights are positioned to create a controlled, repeating reflection that gradually fades into the distance, giving the illusion of depth.
Infinity mirrors are often used in art installations, home décor, and commercial displays because they add a futuristic, dynamic visual element to any space. The concept behind an infinity mirror is based on light reflection and transmission—each time light bounces between the two mirrors, it loses a small percentage of its intensity due to partial transmission through the See-Thru Mirror. This controlled diminishing of light creates the illusion of an infinite space trapped within a finite frame.
Using acrylic sheeting instead of glass for infinity mirrors offers several advantages. Mirror Acrylic and See-Thru / Two-Way Mirror Acrylic are significantly lighter than glass, making them easier to mount, transport, and install, especially for large-scale projects. Acrylic is also shatter-resistant, making it a safer choice for high-traffic environments like retail stores, event spaces, and interactive installations. The optical clarity of high-quality mirror acrylic ensures crisp, sharp reflections without distortion, enhancing the illusion of infinite depth.
How Does an Infinity Mirror Work? The Science Behind the Illusion
The infinity mirror effect is a result of repeated light reflection between a fully reflective mirror and a See-Thru / Two-Way Mirror. Here’s how the process works step by step:
- Light Emission – The LED lights emit light within the enclosed mirror setup.
- First Reflection – The Silver Mirror or Mirror Acrylic at the back fully reflects the light forward.
- Partial Reflection & Transmission – The See-Thru / Two-Way Mirror Acrylic in front reflects a portion of the light while allowing the rest to pass through.
- Repeated Reflection – The transmitted light continues bouncing back and forth between the two mirrors, each time getting weaker due to partial transmission through the See-Thru Mirror.
-
Illusion of Depth – Since each reflection diminishes in intensity, our eyes perceive a gradual fading effect, which creates the illusion of an endless tunnel of light.
Types of Mirrors Used in Infinity Mirrors
Choosing the right mirrors is crucial for achieving the best infinity mirror effect. Each type of mirror plays a specific role in how light reflects and passes through, ultimately determining the illusion’s depth and clarity.
Silver Mirror Acrylic
Silver mirror acrylic, also known as standard reflective mirrors, are the most common type of mirror used in infinity mirrors. These mirrors are highly reflective and create crisp, sharp reflections, making them ideal for the back panel of an infinity mirror setup. Mirror acrylic is often used as a lightweight and shatter-resistant alternative to glass mirror. Mirror acrylic is especially useful in custom builds, interactive exhibits, and large-scale installations where safety and weight are concerns.
See-Thru / Two-Way Mirror Acrylic
See-Thru / Two-Way Mirror Acrylic is the key component that makes the infinity mirror effect possible. This type of mirror allows partial light transmission while reflecting the rest, creating the illusion of repeated reflections that seem to extend endlessly into the mirror. The percentage of light that passes through versus being reflected depends on the specific type of two-way mirror acrylic used. High-quality See-Thru Mirror Acrylic offers a well-balanced combination of reflection and transmission, ensuring that the reflections appear deep and well-defined without excessive light loss. Lower-quality two-way mirrors may cause a dim or less impressive infinity effect due to poor reflection consistency.
Using premium-quality mirrors is essential for achieving a stunning and effective infinity mirror. The combination of a fully reflective silver mirror at the back and a high-grade See-Thru Mirror Acrylic at the front creates the most immersive and visually striking results.
How to Build an Infinity Mirror
Creating an infinity mirror requires precision and attention to detail. To achieve the perfect infinite tunnel effect, each component must be carefully measured, cut, and assembled with accuracy. Follow these steps to build a high-quality infinity mirror:
Step 1: Prepare the Back Mirror
The first step is cutting the back mirror to size. This will serve as the fully reflective surface where the light bounces back. If using mirror acrylic, a fine-tooth saw or laser cutter is ideal for making clean cuts. Ensuring the back mirror is completely flat and free of scratches is crucial for creating crisp reflections.

Step 2: Construct the Frame
The frame must be constructed to house the mirrors and LED strip. Depending on the project, the frame can be made from wood, metal, or acrylic, but it must be deep enough to allow multiple reflections to form. The interior of the frame should be painted black or lined with a non-reflective material to enhance the illusion by preventing unwanted light from escaping.
Step 3: Install the LED Lights
Once the frame is ready, the LED lights are installed. The LED strip is carefully placed along the inner edge of the frame, ensuring the lights are evenly distributed. This positioning allows the light to reflect consistently within the mirror system. A power source and control module can be added at this stage, allowing for adjustable brightness and color changes to create dynamic effects.
Step 4: Cut and Position the See-Thru Mirror
The See-Thru / Two-Way Mirror Acrylic is then cut to match the frame dimensions. This front mirror should fit snugly within the frame while being securely fastened. The See-Thru Mirror must be positioned with the reflective side facing inward, ensuring that it properly reflects light while allowing a portion to pass through. A high-quality See-Thru Mirror with the right reflectivity ratio is crucial for achieving a deep, layered infinity effect. Here at T&T Plastic Land, we cut acrylic to size, so you can order See-Thru / Two-Way Mirror Acrylic directly from our website.
Step 5: Seal and Assemble the Frame
Once all the components are in place, the frame is sealed to ensure proper light containment. Any gaps or loose fittings must be adjusted, as even small imperfections can affect the mirror’s appearance. The mirrors should be aligned perfectly to create a seamless reflection effect.
Step 6: Power Up and Adjust the Infinity Effect
After assembly, the LEDs are powered on to reveal the final infinity effect—a mesmerizing tunnel of light extending into the distance. For optimal performance, adjustments can be made by experimenting with different LED colors, brightness levels, and positioning of the mirrors. A well-built infinity mirror will maintain a consistent, seamless illusion, making it an impressive visual piece for any setting.
