The High Precision 0.9mm UVC 1/4 Lambda Glass Optical Filters are engineered for advanced optical systems requiring exceptional accuracy in ultraviolet spectral control and imaging performance. Designed with a thickness as low as 0.9 mm and manufactured to a 1/4 lambda surface accuracy, these filters ensure minimal wavefront distortion and high optical fidelity, making them particularly suitable for UVC applications and precision photonic systems.
These chromatic optical glass filters are optimized for ultraviolet (UVC) wavelength ranges, typically between 200 nm and 280 nm, where material performance and coating precision are critical. The filters utilize high-grade optical glass substrates combined with specialized coatings to deliver stable spectral filtering, high transmission within target bands, and effective blocking of unwanted wavelengths. This ensures improved signal-to-noise ratios in imaging and detection systems.
Available in diameters ranging from 5 mm to 200 mm, these filters support a wide variety of optical configurations, from compact analytical instruments to large-area imaging setups. The filters are also designed with strict surface quality standards and environmental durability, ensuring long-term stability even under high-energy UVC exposure, which is often challenging for conventional optical components.
