This potassium chloride optical crystal is water-soluble and moisture sensitive, requiring storage in a dry environment. Chemical polishing is not recommended; surface quality and orientation tolerances must be verified before use.
- Moisture Sensitivity: Store the crystal in a dry, low-humidity environment to prevent surface degradation.
- Chemical Polishing Restriction: Do not apply chemical polishing; use only mechanical polishing if surface rework is required.
- Orientation Tolerance: Confirm the orientation tolerance of ±0.5–2° before integrating the crystal into optical assemblies.
- Surface Quality Verification: Inspect the crystal to ensure surface quality meets S/D 80/50 and roughness ≤30 nm.
- Packaging and Cleanliness: Handle and store the crystal in a Class 100 clean bag within a Class 1000 or cleaner environment.
What are the key handling constraints for a KCl optical crystal with a single-side polish and <110> orientation?
This KCl crystal is water-soluble and moisture-sensitive, so chemical polishing is not recommended. It is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner-room environment to prevent surface degradation. The single-side polish requires careful orientation during use to avoid scratching the polished face.
Can this 20 x 20 mm KCl crystal be used as a water-soluble substrate for thin-film separation, and what are the thickness options?
Yes, the product is explicitly designed for water-soluble thin-film substrate workflows. The thickness is customizable from 0.5 to 5 mm, allowing adaptation to different film deposition and lift-off processes. The <110> orientation and cubic crystal structure provide a uniform substrate surface.
What is the transmission range and refractive index of this KCl optical crystal for infrared spectroscopy applications?
The transmission range spans 0.2–27.5 μm, covering ultraviolet to mid-infrared, with a transmission of 91% and a refractive index of 1.49. This broad range and low impurity absorption make it suitable for infrared spectroscopy, prisms, lenses, and laser windows.
Potassium chloride (KCl) optical crystal in <110> orientation with single-side polish and 20×20 mm format provides broad UV-to-mid-IR transmission (0.2–27.5 μm) and serves as a water-soluble substrate for film separation, but requires moisture-controlled handling and cleanroom conditions.
Positive
- Broad UV-to-mid-IR transmission: Transmission range from 0.2 to 27.5 μm covers ultraviolet through mid-infrared, enabling use in infrared spectroscopy, prisms, lenses, filters, and laser windows.
- Water-soluble substrate capability: The crystal's water solubility allows sacrificial substrate use for thin-film deposition and subsequent film-substrate separation workflows.
Trade-offs
- Moisture sensitivity: KCl is water-soluble and moisture sensitive; chemical polishing is not recommended and storage in dry conditions is required to prevent surface degradation.
- Cleanroom handling required: Packaged in Class 100 clean bag and requires Class 1000 or cleaner environment for unpacking and use to maintain surface quality and avoid contamination.
