MATERIAL SOLUTIONS FOR COMPACT CAMERA MODULES

fixed-focus lenses – an image sensor die is bonded to a substrate, which can be made from any number of materials, including FR4, ceramic or gold-plated PCBs. Because pixel counts are increasing to enable greater image resolution, die sizes are getting larger, which can lead to increased warpage. Controlling die warpage and stress with robust die attach materials is critical to highly ...

PIR repair | DIYnot Forums

· 14. Thanks Received: 0. Location: Suffolk. Country: Hi, The plastic lens on a PIR for an external light became brittle and crumbled into pieces. I did a neat repair using some plastic from a plastic squash bottle. It looks like new, but the sensor now barely detects motion unless it is within an inch of the sensor.

Amorphous Materials - Manufacturer of Infrared ...

Amorphous Materials was founded in 1977 to serve as a source of Infrared tranmitting glass or IR glass to be used as optical materials for night vision (FLIR) systems. The word "amorphous" is used to indicate the non-crystalline nature of the IR glass. AMTIR is the acronym for amorphous material transmitting IR radiation.  AMI offers Chalcogenide Glasses, AMTIR-1, AMTIR-2, AMTIR-4, AMTIR-5 ...

How Infrared Motion Detector Components Work

Our FL65 Fresnel lens is made of an infrared transmitting material that has an IR transmission range of 8 to 14 u m which is most sensitive to human body radiation. It is designed to have its grooves facing the IR sensing element so that a smooth surface is presented to the subject side of the lens which is usually the outside of an enclosure that houses the sensor.

Introduction to infrared vision | Resources | Opto Engineering

These materials respond to IR radiation by absorbing photons that elevate the material’s electrons to a higher energy state, causing a change in conductivity, voltage or current. In materials used for quantum detectors, electrons are either in the conduction band, where they are free to move (and therefore conduct electrical current), or in the valence band, where they cannot move freely ...

How do I replace or repair a motion sensor PIR lens?

The PIR lens/translucent cover for my motion sensor for my outdoor light kit broke. Crumbled to the touch after about a year outside despite being made for outdoors. The sensor is now way too sensitive without it, but the sensor does still work. Is it possible to replace this PIR lens, or do I have to throw the baby out with the bathwater and replace the whole sensor piece? I am not asking ...
