Technical Data
Ultraviolet‑fused quartz glass offers a broader spectral range (185 nm–2.1 μm) than K9 optical glass, exhibiting excellent transmittance in the ultraviolet region, a lower refractive index, superior homogeneity, and a smaller coefficient of thermal expansion. It also boasts enhanced chemical resistance and very low fluorescence, making it suitable for fabricating various optical components. A biconvex lens focuses light to a single point, with a positive focal length, and consists of two convex surfaces of equal radius. When the conjugate ratio (object distance: image distance) falls between 5:1 and 1:5, a biconvex lens is the optimal choice for minimizing aberrations; outside this range, planoconvex lenses are typically preferred.
Chongfan Technology’s UV‑grade fused quartz biconvex lenses are available in a wide range of sizes and focal lengths, with both coated and uncoated options. We offer broadband anti‑reflection coatings optimized for the UV spectrum (250–400 nm), catering to diverse applications across multiple wavelength bands and use cases. Custom lens specifications can also be tailored to meet your specific requirements.
