Description
Technical field
This utility model relates to package casing technical field, particularly relates to a kind of photodetector package casing.
Background technology
Radiating away from room-mate of photodetector causes back illumination materials conductive rate to change, and photodetector is in military affairs
There is extensive use with the every field of national economy, be mainly used in radionetric survey and detection, work at visible ray or near infrared band
Industry automatically controls, Photometric Measurement etc., is mainly used in the aspects such as missile guidance, infrared thermal imaging, infrared remote sensing at infrared band.
But existing photodetector is simply simply packaged in shell, this shell can not play mostly to spy
Survey the protective effect of device so that detector in high intensity, is extremely easily damaged under the adverse circumstances such as high acceleration, its air-tightness
Difference, for this, we design a kind of photodetector package casing, solve the problems referred to above.
