Construc­tion and Design of the Most Modern Infrared Detectors

For more than 30 years, our design team has been working together with the construction department to develop the most modern infrared detectors, their technology and special production equipment. Our modular design system allows for a short design stage, even for demanding solutions outside of our standard programme. Based on 3D-CAD, we can develop infrared detectors from first simulations to the start of production. In addition to daily requests for application assistance, we work on the next generation of pyroelectric detectors.

Detector Production of InfraTec

Detector Produc­tion at the Company Headquar­ters in Dresden

The detector production department has all necessary technologies and equipment along with a 1,600m2 cleanroom at their disposal at the company headquarters in Dresden. With this, we have all competencies gathered up, beginning with the evaporation of LiTaO3 chips and detector assembly to final electro-optical measurements.

Detector Produc­tion

Hermetic Welding for all TO detector housings
Detector production: Laser Marking in the dimension of 30 µm
Plasma Cleaning: Surface pre-treatment for gluing, soldering and bonding processes
Triple-target Sputtering System - Deposition of functional layers up to 6"
Wafer dicing: For 2.5" and 25 µm thick LiTaO3 wafers

Detector Production of InfraTec

Our personnel is familiar with modern techniques of simulation, production and testing as well as with various applications of our infrared detectors. Thus, we produce prototypes, small batches and large quantities with highest quality.

We can guarantee long-term competencies in an ever-changing pyroelectric detector market. High quality also requires good organisation, documentation and investments. These requirements form our core-competencies, which ensure our permanent success in the international market:

Patterning of Lithium Tantalate Wafers

  • Crystal characterisation

  • Vacuum coating

  • Infrared absorbent layer

Spec­tral Meas­ure­ments of IR Filters, Char­ac­ter­iz­a­tion and Mounting

  • 100% wafer testing for transmittance, blocking and temperature drift

  • Epoxy adhesive technology for infrared windows and IR filters; soldered windows are available for special applications

Detector Assembly

  • COB in TO metal housings

  • Gold wire bonding at low temperatures

  • Leak-proof sealing of the housings with 99,99 % N2

Final Meas­ure­ments

  • 100 % burn-in testing, including temperature cycling test

  • 100 % gross leak testing

  • Calibrated measurements for automatic signal- and noise measurements

  • Guaranteed storage of production data for complete verification of safety-relevant applications
