This crystal is water-soluble and highly moisture sensitive, requiring storage in a dry, low-humidity environment. Chemical polishing is not recommended due to the material's solubility and risk of surface degradation.
- Moisture Sensitivity: Store the crystal in a desiccated environment or under dry nitrogen to prevent surface degradation from atmospheric moisture.
- Chemical Polishing Restriction: Do not use chemical polishing methods as the crystal dissolves in water and many solvents, compromising surface integrity.
- Cleanroom Handling Requirement: Handle and package the crystal in a Class 1000 or cleaner environment using Class 100 clean bags to avoid particulate contamination.
- Orientation Tolerance: Confirm the <111> orientation within ±0.5–2° tolerance before use in applications requiring precise crystallographic alignment.
- Surface Quality Specification: Maintain surface quality of S/D 80/50 and roughness ≤30 nm to ensure optimal optical transmission and minimize scattering.
What are the key handling constraints for a KBr optical crystal with single-side polish due to its water solubility?
This KBr crystal is water-soluble and moisture-sensitive, so chemical polishing is not recommended. It must be stored and handled in a dry environment; the product is packaged in a Class 100 clean bag and should be opened only in a Class 1000 or cleaner-room environment to prevent surface degradation.
Does the <111> orientation and single-side polish on this 20 x 20 mm KBr substrate affect its compatibility as a water-soluble thin-film substrate?
Yes, the <111> orientation and single-side polish are specifically selected for thin-film substrate workflows where film-substrate separation is required. The cubic crystal structure and 0.2–27.5 μm transmission range support infrared spectroscopy applications, while the water solubility enables clean film release after deposition.
What is the surface quality and roughness specification for this single-side polished KBr crystal, and how does it impact optical performance?
The surface quality is S/D 80/50 with a surface roughness of ≤ 30 nm. This specification ensures low scatter loss for infrared transmission, supporting the stated 91% transmission across the 0.2–27.5 μm range, which is critical for spectroscopy and laser window applications.
This KBr optical crystal offers broad UV-to-mid-IR transmission (0.2–27.5 μm) with high transmission (91%) and low impurity absorption, making it suitable for infrared spectroscopy and thin-film substrate workflows, but its water solubility and moisture sensitivity require careful handling and dry storage environments.
Positive
- Broad UV-to-Mid-IR Transmission: Transmission range from 0.2 to 27.5 μm with 91% transmission and low impurity absorption supports infrared spectroscopy, prisms, lenses, and laser windows.
- Water-Soluble Substrate for Film Separation: The water-soluble nature of KBr allows use as a dissolvable substrate for thin-film deposition and subsequent film-substrate separation in specialized workflows.
Trade-offs
- Moisture Sensitivity Requires Dry Handling: KBr is water-soluble and moisture sensitive; exposure to ambient humidity can degrade surface quality and optical performance, necessitating storage in dry environments and handling in controlled conditions.
- Chemical Polishing Not Recommended: Chemical polishing is unsuitable for this crystal; alternative mechanical polishing methods must be used, adding processing constraints for surface finishing.
