The **Optek Danulat UV-L045 0.45 Calibration Filter (Part No. 1442-0025-0202-13)** is a precision-engineered optical component meticulously designed for high-accuracy spectral calibration in ultraviolet (UV) spectroscopy, photometry, and astronomical instrumentation. This filter represents the pinnacle of optical filtering technology, offering an exceptionally narrow bandwidth centered at 0.45 (angstroms) with a peak transmission efficiency optimized for the far-UV to near-UV spectral range, typically spanning from approximately 120 nm to 250 nm. Crafted from high-purity fused silica substrates, the filter is engineered to minimize intrinsic absorption, scattering, and thermal drift, ensuring long-term stability and reproducibility in demanding research environments. Its unique design incorporates a multilayer dielectric coating, which is precision-tuned to provide an ultra-narrow passband while suppressing stray light and out-of-band radiation by orders of magnitude, thereby enhancing the signal-to-noise ratio in spectroscopic measurements. The filter s robust construction, featuring a durable aluminum or stainless steel housing with precise mounting features, ensures compatibility with a wide range of spectrographs, telescopes, and monochromators, making it an indispensable tool for applications such as stellar spectroscopy, laboratory-based UV analysis, and calibration of high-resolution spectrometers. Whether used in ground-based observatories, satellite-borne instruments, or advanced synchrotron facilities, the UV-L045 filter delivers unparalleled spectral purity, enabling researchers to achieve sub-angstrom resolution and accurate wavelength calibration with confidence. Its reliability and precision make it a cornerstone for scientists and engineers seeking to push the boundaries of optical measurement in the ultraviolet spectrum.
