Lithium Fluoride Window (LiF) Dia. 12.7 mm x Thk. 1.0 mm, Uncoated FAQs

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 12.7 mm x Thk. 1.0 mm, Uncoated?

A1: Lithium Fluoride (LiF) is known for its wide transmission range from the vacuum ultraviolet (UV) region to the infrared (IR). This uncoated 12.7 mm diameter by 1.0 mm thick window has a high damage threshold, low refractive index (around 1.39 at 588 nm), and good resistance to thermal shock. It provides minimal fluorescence and high transparency, making it suitable for spectroscopic, laser, and other optical applications requiring broad wavelength coverage.

Q2: How should this product be handled and stored?

A2: Due to its relatively soft and brittle nature, Lithium Fluoride requires careful handling to prevent scratching or chipping. Always wear clean gloves to avoid contamination by skin oils, and use only lint-free wipes or air blowers for dust removal. Store the window in a low-humidity environment in a protective container to minimise moisture absorption. Avoid harsh chemicals and excessive force, which may compromise the window’s optical quality.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 12.7 mm x Thk. 1.0 mm, Uncoated?

A3: Most manufacturers adhere to ISO 10110 standards for optical component quality, addressing surface imperfections, wavefront distortion, and material inhomogeneity. The LiF window is typically inspected for surface defects under MIL-PRF-13830B guidelines, ensuring consistent clarity and minimal scatter. In addition, RoHS and REACH compliance may be required for environmental and safety regulations. All these standards help guarantee reliable performance for demanding scientific and industrial applications.

1. Quality Control Measures

A thorough evaluation process is essential to ensure the precision and reliability of each Lithium Fluoride Window (LiF) with a diameter of 12.7 mm and thickness of 1.0 mm. From the moment the crystal is cut, technicians use high-resolution inspection tools to verify that surface flatness, parallelism, and dimensional specifications all meet strict tolerances. These evaluations are indispensable for preserving the material’s transparency and for preventing optical aberrations in demanding applications.

Meticulous spectral analysis is another critical step in guaranteeing that uncoated LiF windows consistently provide high transmission across the vacuum ultraviolet (VUV) to infrared range. Any trace unevenness or microscopic defect could diminish the crystal’s performance, so non-contact metrology and environmental testing are conducted under controlled conditions. This commitment to quality control ensures that each 12.7 mm diameter window performs consistently in high-precision optical setups.

2. Applications in Advanced Industries

Classified among the most sought-after optics due to its broad transmission range, the Lithium Fluoride Window (LiF) Dia. 12.7 mm x Thk. 1.0 mm, Uncoated finds use in specialised instruments for spectrum analysis, laser systems, and radiation detectors. By accommodating wavelengths as low as 105 nm in the VUV region, it is particularly valued in synchrotron radiation experiments and precision spectroscopy, where other crystal types do not perform as efficiently.

Taking advantage of LiF’s stable thermal characteristics, industries that require high-performance optics in fluctuating environmental conditions rely on these windows for durability and consistency. They are often integrated into semiconductor manufacturing tools that operate under harsh operating conditions, benefiting from the crystal’s homogeneity. The resulting combination of thermal stability, low dispersion, and high transparency solidifies the LiF window’s role in advanced industrial applications worldwide.
