Fresnel lens the Fresnel lens is a thin, flat optical lens which consists of a series of small narrow concentric grooves on the surface of a lightweight plastic sheet in order to reduce the thickness, weight and cost. Each groove is at a slightly different angle than the next and with the same focal length in order to focus the light toward a central focal point. Every groove can be considered as an individual small lens to bend parallel fresnel light waves and focus the light

How Infrared motion detector components work PIR 325, the pyroelectric sensor is made of a crystalline material that generates a surface electric charge when exposed to heat in the form of infrared radiation. When the amount of radiation striking the crystal changes, the amount of charge also changes and can then be measured with a sensitive FET device built into the sensor, infrared radiation, pyroelectric sensor, RE200B, Fresnel lens, Plano convex lens, S211FL, infrared radiation exists in the electromagnetic spectrum at a wavelength that is longer than visible light
