Does your flame detector need UV Fused Silica Lenses?
Changchun Yutai Optics offers and customizes an extensive range of UV Fused Silica Lenses. Due to its high transmission in the near-infrared (NIR) range (approximately <92% average 400-2000nm) – resulting in a clear distinction between different wavelengths – our UV Fused Silica Lenses are regularly specified for flame detection applications.
Moreover, UV Fused Silica, as a substrate, also has a very low coefficient of thermal expansion (0.55x10-6K-1 at 300K) when compared to N-BK7 (or equivalent) [7.1x10-6K-1], meaning that it can still provide optical performance under high temperature. Its high melting point, compared to N-BK7 (or equivalent), provides further protection for applications operating within high-temperature environments. In fact, UV Fused Silica is comparable to N-BK7 (or equivalent) substrates in terms of performance, having a very similar average transmission over the visible range up to approximately 2000nm and a slightly lower refractive index. Furthermore, the Abbe constants of UV Fused Silica are also very similar to that of N-BK7 (or equivalent), although marginally higher.
We not only offer an extensive range of stock UV Fused Silica Lenses, but we also provide custom-made service. This made-to-measure service allows you to specify the dimensions, substrates, tolerances and optical coatings – if required – that are best suited to your application.
