The transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm.
Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.

(1) GSM Chinese short message alarm, intuitive and reliable, and the transmission distance is not limited;
ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser).
The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.
Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.
The power transformer anti-theft alarm system developed for the actual situation is mainly used for power line and transformer anti-theft alarm. Its characteristics are: no distance limitation, no quantity restrictions, no weather influence, only one alarm center can be set up.
(2) Two wired infrared zones, four wire break zones, which can be customized. The normally open/normally closed contact alarm mode can be selected by self-programming, and the alarm contact adopts photoelectric isolation input to prevent external strong electricity and lightning strike damage, and the alarm state is actively reported to the remote side when the alarm is restored;
(3) A central number and up to 7 short message alarm numbers, can also be automatically alerted by the alarm center computer, electronic map display, with powerful network alarm function;
(4) It has the function of sending start report and remote inspection (test report and timed test test), which can find out whether the work of the alarm host is normal;
(5) Three-phase detection, which can accurately detect and report any phase abnormality;
(6) Chinese alarm information is used in each defense zone, and the user can change the content of the alarm information by himself;
(7) Built-in 12V spare charging polymer battery, automatic charge and discharge control, automatic switching after power failure, can be continued for 48 hours.
