λ/10 N-BK7 Windows

An Optical Window is a transparent optical component that transmits light while acting as a barrier between the detrimental external conditional and sensitive cores inside a system. Apart from the primary function of protection, optical windows might also be used as elements to increase transmission, enhance contrast, or seal a hermetic chamber. Optical windows can be incorporated into a diverse range of optical devices including sensors, cameras, and lasers.

Shalom EO offers stock and custom high-precision λ/10 N-BK7 Windows with multiple coating options: uncoated, 400-700nm, 700-1100nm, 1100-1650nm, the standard coating range covering the VIS and IR spectrum, while customized coatings can also be tailored. Regarding the off-the-shelf products, sizes are standardized which benefits OEM. Laser-line windows are designed in particular to transmit the laser wavelengths while minimizing losses due to absorption or scattering, deflecting harmful laser beams. A combination of several factors including the robustness of the materials, the optical transmission and distortion, and the damage thresholds, etc. must be taken into consideration when manufacturing a laser-line window. Our optical windows are produced using SCHOTT's N-bk7 glass, which is a ROHs-compliant borosilicate glass material renowned for its optical excellence and good comprehensive properties including low cost, wide transmittance to the VIS and NIR spectra, and mechanical/thermal resilience. The exceptional precision (λ/10 flatness and 10/5 S/D surface quality) and the excellent optical, thermal, and mechanical properties of the N-bk7 substrates render our λ/10 n-bk7 windows competent when being utilized as laser-line windows that perform superior transmission and distinguished damage resistance and mechanical strength. Besides, Our λ/10 n-bk7 windows also find versatile utilities in other application fields when designated as plain optical windows.
