A so-called spy mirror makes it possible to observe an illuminated room from a dark room. At the same time, it is impossible to see the observer from the bright room. Only a mirror reflection appears in the bright-lit area so that the observer located on the dark side of the spy mirror is not detected. Due to this effect, such a spy mirror is also called a one-way mirror. This one-way mirror effect is based exclusively on a substantial difference in brightness between the mirror's two sides. A mirror that only transmits from only one side is not feasible for physical reasons. Hence, it is essential for the desired function of a spy mirror that the lighting conditions between the place to be observed and the area from which it is observed differ significantly. The observed space should be illuminated as light as possible for the best results, while the monitored room remains as dark as possible.
You can also use our TDS spy mirror to hide surveillance camera systems. The camera is placed into a box or dark place behind the TDS mirror in such an application. The camera can't be seen from the outside, but the camera can still film through the TDS mirror. However, the camera must provide enough sensitivity to produce an image bright enough in this application.
Our TDS "one-way mirror" is based on a chrome coating applied to a high-quality glass substrate and offers higher image quality and, therefore, a more professional solution than plastic films or acrylic design. For best results, the coated side of the spy mirror should point towards the bright room. The TDS is corrosion-resistant, resistant to water, acids, and other environments, and they are RoHS compliant.
With sufficient quantity, thermal hardening as often necessary for safety-relevant areas is possible. Other optical transmissions and different glass thicknesses are also available for large purchase quantities. Please send us your requirements in case you have special needs or any questions.
