ZnSe window for a cooled IR camera application with the following specifications:
_ diameter 50.8mm +/-0.1
_ thickness: 5mm +/-0.1
_ transmission range: between 2.5 and 13µm
_ coating: without or with DLC on one face and AR on the other if possible (send me two offers with and without coating)

This product is for the replacment on an old camera housing we produced, and we used last time ZnSe window for this application. But camera is used by the marine army, so the window must resit to hatsh environment such as salt and see water.
Do you produce such window? If yes, please send me an offer for one piece.

For your information, the last Ge window we use from your factory were deliver to our customer and the cameras send good results with.

Please contact Del Mar Photonics to request ZnSe window for a cooled IR camera application, or any other requirement for infrared optics.

Infrared Detectors and Systems (Wiley Series in Pure and Applied Optics)
E. L. Dereniak (Author), G. D. Boreman (Author)

Product Description
This text covers the range of subjects necessary for the understanding of modern infrared-imaging systems at a level appropriate for seniors or first-year graduate students in physics or electrical engineering. The first six chapters focus on fundamental background issues of radiation detection, beginning with the basics of geometrical optics and finishing with a discussion of the figures of merit used for describing the signal-to-noise performance of a detector system. Other topics include radiometry and flux-transfer issues, basic radiation-detector mechanisms, and random-process mathematics.

The presentation then moves on to specific detector technologies and the fundamental mechanisms of detection, paying special attention to responsivity and noise performance. Devices discussed include photovoltaic detectors, photoconductive detectors, thermal detectors, Schottky-barrier diodes, and bandgap-engineered photodetectors via multiple quantum wells and superlattices.

The book concludes with a close look at infrared detection systems and related issues. In the discussion of infrared search systems, the range equation is developed in terms of the optical and detector parameters of the system. A separate chapter is devoted to modulation transfer function, a spatial-frequency-domain description of image quality. The final chapter describes the design equations for thermal-imager systems in terms of noise-equivalent temperature difference and minimum resolvable temperature.

Supported and clarified by 470 illustrations and accompanied by an extensive glossary of the nomenclature, this is an excellent text for graduate and senior level courses in radiometry and infrared detectors. It is also a valuable reference for practicing engineers involved in the use, design, analysis, and testing of infrared detector-based systems.

Infrared Detectors and Systems is a complete, accessible, and timely exposition of a technology whose applications are increasingly important and widespread. Based on courses presented by two of the field's leading figures, this book provides extensive coverage of the background and fundamentals of radiation detection and goes on to examine specific technologies and systems in depth and, in some cases, for the first time in print.

Technologies discussed include

* Photovoltaic detectors
* Photoconductive detectors
* Thermal detectors
* Schottky-barrier diodes
* Bandgap-engineered photodetectors via multiple quantum wells and superlattices

Supplemented with 470 illustrations and a complete glossary of the nomenclature, this is the ideal text for senior- and graduate-level courses in radiometry and optical detection.
