This crystal is water-soluble and highly moisture sensitive, requiring storage in a dry environment. Chemical polishing is not recommended due to the risk of surface degradation.

  • Moisture Sensitivity: The crystal must be stored in a dry atmosphere to prevent dissolution or surface damage.
  • Water Solubility: Contact with water or high humidity will dissolve the crystal surface, compromising optical quality.
  • Packaging Requirement: The crystal is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner environment.
  • Orientation Tolerance: The <111> orientation tolerance is ±0.5–2°, which must be verified before use.
  • Surface Quality Constraint: Surface quality is specified as S/D 80/50 with roughness ≤30 nm, requiring careful handling to avoid scratches.

What are the key handling constraints for a KCl optical crystal with <111> orientation and single-side polish?

This KCl crystal is water-soluble and moisture-sensitive, so it must be stored and handled in a dry environment. Chemical polishing is not recommended. The product is packaged in a Class 100 clean bag and should be opened only in a Class 1000 or cleaner-room environment to maintain surface quality.

What is the transmission range and refractive index of this KCl crystal for infrared spectroscopy applications?

The KCl crystal transmits from 0.2 to 27.5 μm, covering ultraviolet to mid-infrared, with a refractive index of 1.49 and transmission of 91%. This broad range and low impurity absorption make it suitable for infrared spectroscopy, prisms, lenses, and laser windows.

Can this KCl crystal be used as a water-soluble thin-film substrate, and what are the size and polish options?

Yes, the water solubility of KCl enables film-substrate separation workflows. The product is supplied as a 10 x 10 mm single-side polished crystal with <111> orientation. Thickness is customizable from 0.5 to 5 mm, and double-side polish options are available for other configurations.

This KC1 optical crystal with <111> orientation, single-side polish, and 10×10 mm format offers broad 0.2–27.5 μm transmission and 91% transmission with low impurity absorption, making it suitable for infrared spectroscopy and water-soluble thin-film substrate workflows. Its water solubility and moisture sensitivity impose strict handling and storage requirements, and the surface quality (S/D 80/50, roughness ≤30 nm) may limit use in ultra-precision optics.

Positive

  • Broad UV-to-MIR transmission: Transmits from 0.2 to 27.5 μm with 91% transmission and low impurity absorption, enabling infrared spectroscopy and multi-spectral optical component applications.
  • Water-soluble substrate capability: Acts as a sacrificial water-soluble substrate for film-substrate separation, a property exploited in thin-film transfer workflows.

Trade-offs

  • Moisture and handling sensitivity: Water-soluble crystal requires controlled ambient humidity; chemical polishing is not recommended, and handling must be performed in clean, dry conditions (Class 1000 or better).
  • Moderate surface quality specification: Surface quality S/D 80/50 and roughness ≤30 nm may be insufficient for high-power laser windows or applications demanding sub-nanometer smoothness.
