plasticinfrared

These are the Fresnel lenses for the Murata pyroelectric infrared sensors. Select the lens which is best suited to the required detection area. Features Because a Fresnel lens can be made thinner in comparison to a typical convex lens, it helps make sensors lighter and smaller. It is designed to pass the rays through the same point (focal point) and possesses the same function as a typical lens. Applications Select the lens according to the detection area and mounting location. The following page explains infrared sensor lens necessity.
