IdealPhotonics' ultraviolet lens is a transmission component specifically designed for optical imaging in the ultraviolet band (200-400nm). It utilizes special materials and coating processes such as calcium fluoride (CaF₂) or fused silica to ensure high ultraviolet transmittance and low aberrations, making it suitable for ultraviolet microscopy, photolithography, and fluorescence detection.Key parameters include ultraviolet transmittance (>80%@specific wavelengths, such as 254nm), material (CaF₂/MgF₂), aberration correction level (wavefront error <λ/4), damage resistance threshold (J/cm²), and coating weather resistance. These parameters directly determine its light energy utilization and stability in ultraviolet imaging.
