This crystal requires strict moisture control to prevent dissolution or damage. Chemical polishing is contraindicated due to the water-soluble nature of the material.
- Moisture Sensitivity: Store and handle in a dry environment (cleanroom class 1000 or better) to avoid surface degradation.
- Surface Finish Maintenance: Maintain specified surface quality (S/D 80/50) and roughness (≤30 nm) by avoiding contact with solvents or abrasive cleaning.
- Orientation Tolerance: The <111> orientation is held to ±0.5–2°; verify prior to optical alignment.
- Packaging Integrity: The crystal is supplied in a Class 100 clean bag and must remain in a cleanroom environment until use.
- Handling Protocol: Use only clean, dry tools and avoid exposure to high humidity during mounting or transfer.
What is the transmission range and efficiency of the KCl optical crystal, and how does its moisture sensitivity limit its operational environment?
The KCl crystal transmits from 0.2 to 27.5 μm with 91% transmission. However, it is water-soluble and moisture sensitive, so it must be handled in low-humidity environments and stored in Class 100 clean bags; chemical polishing is not recommended. This limits its use in ambient or humid conditions without proper protection.
Can this double-side polished KCl crystal be used as a water-soluble substrate for thin-film deposition and subsequent film separation?
Yes, the double-side polished KCl crystal is explicitly designed as a water-soluble substrate for film-substrate separation workflows. The 10×10 mm format and <111> orientation are suitable for such applications. However, the crystal's moisture sensitivity requires careful handling to avoid dissolving the substrate prematurely.
What are the specific handling, storage, and packaging requirements for KCl optical crystals to prevent damage?
KCl crystals are water-soluble and moisture sensitive; they must be stored in a dry environment (Class 1000 or cleaner room). The product is packaged in a Class 100 clean bag. Chemical polishing is not recommended because it can damage the surface. Orientation tolerance is ±0.5–2°, and surface roughness is ≤30 nm, so gentle handling with appropriate tools is required to avoid scratches.
This KCl optical crystal offers a broad 0.2–27.5 μm transmission range and 91% transmission, making it suitable for infrared spectroscopy and optical components, while its water solubility and moisture sensitivity require controlled handling and storage environments.
Positive
- Broad UV-to-Mid-IR Transmission: Transmission range of 0.2–27.5 μm with 91% transmission and low impurity absorption enables use in infrared spectroscopy, prisms, filters, and laser windows.
- Water-Soluble Substrate Capability: The crystal's water solubility allows it to serve as a dissolvable substrate for thin-film deposition and subsequent film-substrate separation in specialized workflows.
Trade-offs
- Moisture Sensitivity and Handling Constraints: The crystal is water-soluble and moisture sensitive; chemical polishing is not recommended, and dry storage in a controlled environment is required to prevent surface degradation.
- Orientation Tolerance and Specification Confirmation: Orientation tolerance is ±0.5–2° and thickness, polish, and surface finish must be confirmed before ordering, requiring careful specification matching for precision applications.
