Q1: What are the key material properties of Thallium Bromide Iodide Window (KRS-5) Dia. 25.4 mm x 3 mm, Uncoated?

A1: Thallium Bromide Iodide (KRS-5) is known for its high refractive index (approximately 2.37 at 10 µm) and exceptional infrared (IR) transmittance ranging from 0.6 µm to 40 µm. It displays relatively low hardness, making it susceptible to scratching. Its composition of thallium bromide and thallium iodide provides good chemical stability but requires caution due to toxicity. The material also offers minimal dispersion, which is advantageous in various IR optical applications.

Q2: How should this product be handled and stored?

A2: KRS-5 windows must be handled using clean gloves to avoid skin contact and potential contamination. Their softness requires gentle handling and protective packaging to prevent scratches or chipping. Store them in a low-humidity environment, ideally within a desiccator or sealed container. Avoid exposure to harsh chemicals and ensure proper labelling to minimise handling errors and prevent accidental damage to the delicate surface.

Q3: Which quality standards and certifications apply to Thallium Bromide Iodide Window (KRS-5) Dia. 25.4 mm x 3 mm, Uncoated?

A3: These windows generally conform to ISO 9001:2015 manufacturing standards to ensure consistent quality and traceability. Most reputable suppliers also follow MIL-PRF or MIL-STD guidelines to meet strict military specifications for optical components. Some may include RoHS compliance if applicable, and in certain cases, detailed documentation or certification of conformance is provided to verify transmission, dimensional accuracy, and surface quality requirements.

1. Manufacturing Process

Tightly controlled growth of Thallium Bromide Iodide (KRS-5) crystals under carefully monitored thermal conditions forms the foundation of manufacturing the Dia. 25.4 mm x 3 mm windows. Liquid melt techniques, such as the Bridgman method, are frequently employed to ensure consistent crystal quality throughout each ingot. These large ingots are then sectioned into disks of precise thickness, which helps maintain uniform optical performance across the entire surface area. Skilled technicians use specialised saws and diamond-impregnated blades to slice the raw crystal into circular blanks ready for further refinement.

Diligent polishing follows the slicing stage, eliminating any surface imperfections and optimising the uncoated window for maximum infrared transmittance. Multiple laps with progressively finer abrasives ensure smoothness at the submicron level, thereby enhancing clarity and reducing scattering within the mid to far-infrared spectrum. Final inspections involve dimensional checks for exact thickness, as well as surface integrity and flatness measurements, ensuring that each 25.4 mm diameter KRS-5 window meets stringent optical and physical specifications.

2. Applications in Advanced Industries

Advanced spectroscopy setups rely on Thallium Bromide Iodide windows for their high transmission capabilities across a wide infrared spectrum. This characteristic makes the uncoated KRS-5 window particularly valuable in chemical analysis laboratories, where precise and rapid detection of organic and inorganic compounds is vital. Additionally, the combination of chemical stability and low refractive index variation under changing temperatures renders KRS-5 windows suitable for specialised medical equipment that utilises infrared imaging techniques.

Specialised aerospace and defence applications further capitalise on these windows due to their ability to function in challenging environments while maintaining high optical clarity. The Dia. 25.4 mm x 3 mm format is easily integrated into compact sensing devices used for thermal mapping and surveillance. Because KRS-5 exhibits minimal distortion and maintains consistent performance across a broad range of infrared wavelengths, it remains a preferred material for high-precision system designs in demanding industrial sectors worldwide.
