This optical crystal is water-soluble and moisture sensitive, requiring storage in a low-humidity environment. Chemical polishing is not recommended and physical handling must avoid surface contamination and humidity exposure.
- Moisture Sensitivity: The crystal is water-soluble and must be stored in a dry, low-humidity environment to prevent dissolution or surface degradation.
- Polishing Constraint: Chemical polishing is not recommended as it may damage the surface quality of the crystal.
- Cleanroom Handling: The crystal is packaged in a Class 100 clean bag and should be handled in a Class 1000 or cleaner environment to avoid contamination.
What are the key handling constraints for a KCl optical crystal with double-side polish due to its water solubility?
This KCl crystal is water-soluble and moisture-sensitive, so chemical polishing is not recommended. It is packaged in a Class 100 clean bag within a Class 1000 or cleaner-room environment to protect the polished surfaces. Users must avoid exposure to humidity and aqueous cleaning to prevent surface degradation.
Does the <100> orientation and double-side polish on this 10 x 10 mm KCl crystal affect its transmission range or refractive index?
The specified <100> orientation and double-side polish do not alter the intrinsic optical properties of KCl. The transmission range remains 0.2–27.5 μm with a refractive index of 1.49 and transmission of 91%. The orientation tolerance is ±0.5–2°, and the double-side polish ensures low surface roughness (≤ 30 nm) for consistent optical performance in infrared spectroscopy and laser window applications.
What are the typical applications where this KCl crystal's water solubility is an advantage rather than a limitation?
The water solubility of this KCl crystal is specifically advantageous for water-soluble thin-film substrate workflows, where the crystal can be dissolved to separate deposited films. It is also suitable for infrared spectroscopy, prisms, lenses, filters, cell windows, and laser windows, provided that moisture exposure is controlled during use.
This 10×10 mm double-side polished KCl crystal with <100> orientation offers broadband transmission from 0.2 to 27.5 μm at 91% efficiency, making it suitable for infrared spectroscopy and thin-film substrate applications. Its water solubility enables film-substrate separation but requires strict moisture control and forbids chemical polishing.
Positive
- Broad UV-to-MIR transmission: Transmits from 0.2 to 27.5 μm with 91% transmission, covering ultraviolet through mid-infrared for spectroscopy and optical component applications.
- Water-soluble substrate capability: The crystal's water solubility enables film-substrate separation workflows, a unique advantage for thin-film transfer processes.
Trade-offs
- Moisture-sensitive handling required: KCl is water-soluble and moisture sensitive; chemical polishing is not recommended. Storage and processing must be in dry, controlled environments.
- Moderate surface quality specification: Surface quality is S/D 80/50 with roughness ≤ 30 nm, which may be insufficient for applications requiring ultra-smooth or high-power laser optics.
