This potassium bromide optical crystal is water-soluble and moisture sensitive, requiring controlled humidity handling. Chemical polishing is not recommended due to material solubility, and the crystal must be stored and used in a cleanroom environment to maintain surface quality.
- Moisture Sensitivity: The crystal is water-soluble and moisture sensitive; exposure to ambient humidity may cause surface degradation.
- Chemical Polishing Restriction: Chemical polishing is not recommended because the material dissolves in water.
- Cleanroom Handling Requirement: The crystal is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner environment.
- Surface Quality Constraint: Surface quality is specified as S/D 80/50 with roughness ≤30 nm; avoid contact that could introduce scratches or contamination.
- Orientation Tolerance: Crystal orientation tolerance is ±0.5–2°; verify orientation before use.
What are the key performance trade-offs of using a <110>-oriented KBr crystal for infrared spectroscopy compared to other orientations?
The <110> orientation provides a specific crystallographic plane that can influence birefringence and mechanical stability for optical applications. This product is double-side polished with a surface roughness ≤30 nm and surface quality S/D 80/50, ensuring low scatter in the 0.2–27.5 μm transmission range. However, the water-soluble nature of KBr and its moisture sensitivity require careful handling, as chemical polishing is not recommended and the crystal must be stored in a dry environment to maintain optical performance.
Can this KBr crystal be used as a water-soluble substrate for thin-film separation, and what are the integration constraints?
Yes, the product is explicitly described as a water-soluble substrate for film-substrate separation workflows. The 10 x 10 mm format with double-side polish and <110> orientation is suitable for depositing thin films that can later be released by dissolving the KBr in water. Key constraints include the crystal's moisture sensitivity, requiring handling in a Class 1000 or cleaner-room environment, and the need to avoid chemical polishing, which could damage the surface.
What handling and storage infrastructure is required for this moisture-sensitive KBr optical crystal?
The 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. It is packaged in a Class 100 clean bag and should be used in a Class 1000 or cleaner-room environment. Chemical polishing is not recommended; only mechanical polishing or gentle cleaning methods should be employed to preserve surface quality.
This KBr optical crystal with <110> orientation and double-side polish offers a broad transmission range of 0.2–27.5 μm and 91% transmission, suitable for infrared spectroscopy and thin-film substrate applications. However, its water solubility and moisture sensitivity require careful handling, and the orientation tolerance of ±0.5–2° may limit precision alignment.
Positive
- Broad UV-to-mid-IR transmission: Transmission range from 0.2 to 27.5 μm enables use across ultraviolet to mid-infrared spectroscopy and optical component applications.
- High transmission with low absorption: 91% transmission with low impurity absorption and double-side polish reduces scattering losses for improved optical throughput.
Trade-offs
- Water solubility and moisture sensitivity: Crystal is water-soluble and moisture-sensitive; chemical polishing is not recommended. Requires dry storage and handling in controlled environments to prevent degradation.
- Orientation tolerance limits precision: Orientation tolerance of ±0.5–2° may be insufficient for alignment-critical applications requiring tighter angular control.
