Potassium Bromide Window (KBr) Dia. 25.4 mm x Thk. 4.0 mm, Uncoated FAQs

Q1: What are the key material properties of Potassium Bromide Window (KBr) Dia. 25.4 mm x Thk. 4.0 mm, Uncoated?

A1: Potassium Bromide (KBr) is an ionic crystal that exhibits excellent infrared transmission from around 0.2 µm to 25 µm, making it ideal for IR spectroscopy. This uncoated window offers a refractive index around 1.52 at 10 µm, enabling minimal distortion. It has a relatively low hardness of about 16 (Knoop), requiring cautious handling. Chemically, it is highly water-soluble and hygroscopic, necessitating storage in a controlled, low-humidity environment.

Q2: What handling precautions and storage conditions are recommended for this uncoated KBr window?

A2: Due to its softness and hygroscopic nature, the KBr window must be handled with clean gloves or tweezers to avoid surface damage and contamination. Any contact with moisture should be minimised, so it is best stored in a desiccator or sealed container with low humidity. Care should be taken to prevent scratches or chipping, and the window should not be exposed to harsh cleaning solutions or abrasive materials.

Q3: Which quality standards and certifications apply to Potassium Bromide Window (KBr) Dia. 25.4 mm x Thk. 4.0 mm, Uncoated?

A3: These KBr windows commonly comply with ISO 9001 manufacturing standards to ensure consistent quality and dimensional accuracy. They often undergo spectral transmission and surface quality inspections in accordance with MIL-PRF-13830B or equivalent guidelines. Each unit is typically delivered with conformity documentation specifying optical tolerances, flatness, and surface imperfection limits, confirming adherence to industry standards for optical components of this type.

1. Material Properties and Advantages

This uncoated Potassium Bromide Window (KBr), measuring 25.4 mm in diameter and 4.0 mm in thickness, is highly regarded for its excellent infrared transmission capabilities extending from the near-IR to the far-IR region. It provides minimal light absorption across a wide spectral range, which makes it ideal for use in spectroscopic applications that demand accurate measurements. Additionally, its low refractive index ensures minimal scattering of incident radiation, preserving signal integrity in high-precision instrumentation.

Optimal optical clarity and chemical stability further enhance the window’s suitability in environments where consistent performance is essential. Although KBr is hygroscopic by nature, proper handling and storage procedures can significantly extend the component’s useful life. This characteristic allows researchers and engineers to capitalise on the window’s superior optical qualities for specialised tasks, such as laser-based experimentation and innovative photonic applications.

2. Comparative Analysis with Alternative Materials

When evaluating this KBr window against other infrared materials like Calcium Fluoride and Zinc Selenide, one key advantage is its ability to transmit over a broader spectral range without significant attenuation. While Calcium Fluoride excels in the ultraviolet and near-infrared regions, it cannot match KBr’s reach into far-IR wavelengths. Similarly, Zinc Selenide offers good infrared properties but often requires additional coatings or designs to address scattering problems that are less pronounced in KBr.

Further distinguishing KBr is its relatively easier machinability and fabrication potential, making it a more economical option for certain specialised applications. In high-end IR spectroscopy, the uncoated Potassium Bromide Window (Dia. 25.4 mm x Thk. 4.0 mm) provides a valuable combination of transparency, precision, and compatibility with sensitive analytical equipment. By balancing cost efficiency and technical performance, it stands out as a dependable choice in diverse industrial, research, and scientific environments.
