- Transmits wavelength range 1.2-7 μm
- Ideal for weight sensitive applications
- Cheaper than germanium and ZnSe
Silicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2 – 7μm spectral region due to their low cost and low density. Due to its low density (half that of germanium or zinc selenide), silicon is ideal for weight sensitive applications, especially those in the MWIR thermal imaging 3 – 5μm region. Density is 2.329 g/cm3 and Knoop Hardness is 1150, making it harder and less brittle than germanium.

Inspection is necessary for high power and high voltage electric installations to avoid the possible accident, the thermal imagine is found to be the optimal and effective way for this application. In some countries, thermal imagine inspections is compulsory for accident insurance. And in some industrial equipment likethe high temperature metallurgic oven, it is necessary to use the thermal imagine to watch its temperature inside. An infrared windows assembly is needed to be installed on the housing of the electric and industrial equipment as the viewport windows for thermal image camera.
High power and high voltage electric installations, switch cabinet;
High temperature metallurgic oven;
Mineral and petroleum industry.
Design and standard
The windows assembly consists of metal flange, crystals windows and metal protective cover;
The protective cover is fixed by two small magnet nubs;
The whole windows is fixed on the cabinet house by the flange, no screw is needed;
Various types of infrared crystals is available: CaF2; BaF2; Germanium; Sapphire; Silicon; ZnS; ZnSe;
Confirm to the dust tight standard IP67 of NF EN6052.

Step 1: Calculate and decide the position where the windows would be installed according to the view angle of the thermal imagine camera;
Step 2: Drill a hole according to the size of the windows assemblies;
Step 3: Install the whole windows assemblies;
Step 4: Open the protective cover and make the testing of the inspection.
Select the suitable crystals materials for your applications:
Several factors you should take into consideration during the selection of crystals materials: Wavelength range, environment (temperature, humidity and vibration ect.) and cost. Here is the specification of the materials for your reference.
