laser optics windows are essential components used to separate different environments, such as the interior and exterior of an instrument, thereby protecting internal devices. These basic optical elements do not alter magnification but do influence the optical path. Key parameters for optical windows include light transmittance, surface accuracy, thickness, parallelism, and substrate material. Bena Optics provides high-precision windows made from various materials, including zinc selenide, germanium, silicon, barium fluoride, and calcium fluoride for infrared applications; fused silica and sapphire for spectral bands; and K9 glass for visible light. They maintain a large inventory of standard products and also offer custom optical windows tailored to specific needs.

Key Features of Optical Window
Optical windows possess high transmittance, hardness, erosion resistance, low thermal expansion, and minimal absorption loss, ensuring stable performance in various environments.

Made from materials like UV fused silica, quartz, infrared crystals, and optical glass, they offer excellent light transmission, high-temperature resistance, corrosion resistance, and electrical insulation. UV fused silica, for instance, has over 93% transmittance across the UV to IR spectrum.

Widely used in aerospace, laser systems, scientific research, and detectors, optical windows protect internal components and isolate external environments while maintaining high transmittance for specific wavelengths.

The Applications of Optical Window
Optical windows protect optical systems and sensitive electronics from external environments. Made of polished optical glass, they allow light transmission while isolating physical environments.

Infrared window detection viewpoint window

The infrared windows are the optical devices that pervious to the ultraviolet, visible light and infrared light. They are installed on the electrical cabinet, join with infrared thermal imager, will provide the continuous non-destructive detection for the internal equipment in electrical cabinet.

Product Description


Main features:

Audio-Visual: 0.15�¼m -15�¼m transmission range is suitable for all range of infrared thermal imager, infrared thermometer and ultraviolet thermal imager.

Safe: prevent from the detriment under the atrocious working conditions such as electromagnetic radiation, high voltage or high temperature. Make the thermometric components work under the high temperature in electrical cabinet without interrupt the power supply.

Speedy: only few minutes for mounting or adapting, plug and play.

Economical: take the temperature without cutting off the power, interrupting the production or the equipment operation, which saves the expanse.
Needs NO special maintenance.
