Exploration of the Application of 3D Printed Zirconia Materials in Infrared Detectors
Dewar provides a good low-temperature working environment and light,mechanical,electrical,and thermal transmission channels for infrared focal plane detectors.The cold table support structure serves as the bearing platform of the infrared detector,bearing the effects of equipment transportation,vibration,impact,etc.,which puts higher requirements on the strength of the support structure.Therefore,it is necessary to de-velop new support structures to improve the reliability of dewar.Based on the demand for low conduction heat leakage and high reliability of infrared detector components,different support structure materials were analyzed from both macroscopic and microscopic perspectives,and the influence of support structures prepared by two molding processes on the design and manufacturing of infrared detectors was compared.Compared with tradi-tional processing methods,the accuracy of zirconia formed by digital light processing(DLP)technology can reach+0.03 mm,which is consistent with the standard card of XRD diffraction peak.This indicates that its purity is high,and this technology can shorten the processing time and optimize the packaging process.
