This crystal is water-soluble and moisture-sensitive, requiring storage in a dry environment. Chemical polishing is not recommended due to risk of surface damage.
- Moisture Sensitivity: Store the crystal in a desiccated environment to prevent water absorption and surface degradation.
- Chemical Polishing Restriction: Do not apply chemical polishing methods as they can irreversibly damage the crystal surface.
- Cleanroom Handling: Handle the crystal in a Class 1000 or cleaner environment and keep it in its Class 100 clean bag until use.
- Orientation Verification: Verify the <100> orientation tolerance of ±0.5–2° before integration into optical assemblies.
- Surface Protection: Avoid contact with abrasive materials to maintain surface quality S/D 80/50 and roughness ≤30 nm.
What are the key handling constraints for KCl optical crystals due to water solubility?
KCl is a water-soluble crystal and highly moisture sensitive; chemical polishing is not recommended. The product is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner-room environment to prevent surface degradation. These constraints directly impact storage, cleaning, and integration workflows for infrared spectroscopy or thin-film substrate applications.
Does this KCl crystal support film-substrate separation for water-soluble thin-film workflows?
Yes, the double-side polished KCl crystal is explicitly listed as a water-soluble substrate for film-substrate separation applications. Its broad transmission range of 0.2–27.5 μm and high transmission of 91% make it suitable as a sacrificial substrate in infrared spectroscopy and thin-film workflows where the substrate must be dissolved after film deposition.
What are the orientation and surface quality tolerances for this <100> KCl crystal?
The crystal orientation tolerance is ±0.5–2° for the <100> orientation, with surface quality specified as S/D 80/50 and surface roughness ≤ 30 nm. Thickness is customizable from 0.5 to 5 mm, and the standard size is 20 x 20 mm with double-side polish. These tolerances are critical for consistent optical performance in prisms, lenses, and laser windows.
This Potassium Chloride optical crystal with <100> orientation and double-side polish offers broad UV-to-mid-IR transmission (0.2–27.5 μm) and high transmission at 91%, making it suitable for infrared spectroscopy and thin-film substrate applications, but its water solubility and moisture sensitivity require controlled handling and limit chemical polishing options.
Positive
- Broad UV-to-mid-IR transmission: Transmission range from 0.2 to 27.5 μm covers ultraviolet through mid-infrared, enabling versatile use in spectroscopy and optical components.
- High transmission with low impurity absorption: 91% transmission with low impurity absorption ensures efficient optical performance for demanding applications.
Trade-offs
- Water-soluble and moisture sensitive: The crystal is water-soluble and requires handling in dry environments; exposure to moisture can damage the surface or bulk material.
- Chemical polishing not recommended: Chemical polishing is not recommended for this material, limiting surface finishing options and requiring alternative mechanical polishing methods.
