This potassium bromide crystal is water-soluble and moisture-sensitive, requiring controlled humidity storage. Chemical polishing is not recommended due to the crystal's solubility and surface quality requirements.
- Moisture Sensitivity: The crystal dissolves in water and degrades in high humidity, requiring storage in a dry environment.
- Chemical Polishing Restriction: Chemical polishing is not recommended as it may damage the surface finish and optical quality.
- Storage Environment: The crystal should be stored in a Class 100 clean bag within a Class 1000 or cleaner room to prevent contamination.
What are the key handling and storage constraints for this KBr optical crystal given its water solubility?
This KBr crystal is water-soluble and moisture-sensitive, so it must be stored in a dry environment and handled with care to avoid exposure to humidity. The product is packaged in a Class 100 clean bag under Class 1000 or cleaner-room conditions, and chemical polishing is not recommended. These constraints are critical for maintaining the specified surface quality (S/D 80/50) and surface roughness (≤ 30 nm).
Does this single-side polished <100> KBr crystal support thin-film substrate separation workflows?
Yes, the product description explicitly lists water-soluble thin-film substrate workflows as an application. The single-side polish on a 10 x 10 mm <100> orientation crystal provides a smooth surface for film deposition, and the water solubility of KBr enables subsequent film-substrate separation by dissolving the crystal in water. This is a distinct advantage over non-soluble substrates for certain transfer processes.
What is the transmission range and refractive index of this KBr crystal for infrared spectroscopy applications?
The KBr crystal offers a broad transmission range from 0.2 to 27.5 μm, covering ultraviolet to mid-infrared wavelengths, with a refractive index of 1.49 and transmission of 91%. These specifications make it suitable for infrared spectroscopy components such as cell windows, prisms, and laser windows, though the single-side polish may require orientation toward the beam path for optimal performance.
This 10 x 10 mm <100>-oriented KBr crystal with single-side polish offers broadband 0.2–27.5 μm transmission at 91% for infrared spectroscopy and thin-film substrate workflows, but its water solubility and moisture sensitivity require controlled handling and storage.
Positive
- Broad UV-to-MIR transmission: Transmission range of 0.2–27.5 μm with 91% transmission and low impurity absorption supports infrared spectroscopy, prisms, lenses, filters, and laser windows across a wide spectral band.
- Water-soluble substrate capability: The crystal's water solubility enables film-substrate separation workflows, allowing thin-film removal by dissolution in aqueous media.
Trade-offs
- Moisture-sensitive handling required: As a water-soluble crystal, it is moisture sensitive; chemical polishing is not recommended, and exposure to humid environments can degrade surface quality.
- Cleanroom packaging dependency: Supplied in Class 100 clean bags and requiring a Class 1000 or cleaner environment, the crystal demands controlled storage and handling to maintain its S/D 80/50 surface quality.
