This crystal is water-soluble and moisture-sensitive, requiring storage in a dry, low-humidity environment. Chemical polishing is not recommended; only mechanical polishing methods should be used to maintain surface integrity.
- Moisture Sensitivity: The crystal must be stored in a desiccated environment to prevent dissolution or surface degradation.
- Polishing Restriction: Avoid chemical polishing as it can damage the crystal surface; use only mechanical polishing techniques.
- Orientation Tolerance: The crystal orientation tolerance is ±0.5–2°, which must be verified before use in precision optical applications.
- Surface Quality: Surface quality is specified as S/D 80/50 with roughness ≤30 nm, requiring careful handling to avoid scratches.
- Packaging Requirement: The crystal is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner environment to prevent contamination.
What are the key handling constraints for a KCl <110> double-side polished crystal due to its water solubility?
This KCl crystal is water-soluble and moisture-sensitive, so chemical polishing is not recommended. It must be handled in a dry environment and stored in a Class 100 clean bag within a Class 1000 or cleaner room to prevent surface degradation. The moisture sensitivity directly impacts its use as a water-soluble thin-film substrate for film-substrate separation workflows.
Does the 20 x 20 mm KCl crystal with <110> orientation support mid-infrared spectroscopy applications?
Yes, this crystal is suitable for infrared spectroscopy due to its broad transmission range of 0.2–27.5 μm, which covers the ultraviolet to mid-infrared region. With a refractive index of 1.49 and 91% transmission, the double-side polished <110> orientation and 20 x 20 mm format are specifically designed for prisms, lenses, filters, cell windows, and laser windows in spectroscopy setups.
What are the orientation and surface quality tolerances for this KCl optical crystal?
The crystal orientation tolerance is ±0.5–2° for the <110> direction, and the surface quality is specified as S/D 80/50 with a surface roughness of ≤ 30 nm. Thickness is customizable from 0.5 to 5 mm, and the double-side polish is confirmed before quotation to meet application-specific requirements.
This KCl optical crystal (SKU AF-IR-C-KCL1-T025-BD20) with <110> orientation, double-side polish, and 20×20 mm format is evaluated for infrared spectroscopy and water-soluble thin-film substrate applications. Its broad transmission range (0.2–27.5 μm) and 91% transmittance provide strong optical performance, but the material's water solubility and moisture sensitivity demand strict environmental control and specialized handling procedures.
Positive
- Broad UV-to-mid-IR transmission: Transmission range of 0.2–27.5 μm with 91% transmittance and low impurity absorption, enabling spectroscopy and optical component use from ultraviolet to mid-infrared.
- Water-soluble substrate capability: The crystal's water solubility allows film-substrate separation workflows, making it suitable for thin-film transfer processes in research applications.
Trade-offs
- Moisture-sensitive handling required: KCl is water-soluble and moisture sensitive; chemical polishing is not recommended. Storage and handling must be performed in low-humidity, clean-room conditions (Class 1000 or better) to prevent surface degradation.
- Precision tolerances need verification: Orientation tolerance is ±0.5–2° and surface quality is S/D 80/50 with roughness ≤30 nm. For applications requiring tighter tolerances, specification confirmation before quotation is essential.
