Potassium Chloride (KCl) optical crystals are water-soluble and moisture-sensitive, requiring storage in a dry environment to prevent surface degradation. Chemical polishing is not recommended due to the crystal's solubility, and handling must be performed in a cleanroom environment to avoid contamination.
- Moisture Sensitivity: The crystal is water-soluble and must be kept in a low-humidity environment to prevent dissolution or surface deterioration.
- Chemical Polishing Restriction: Chemical polishing is not recommended as it can damage the crystal surface.
- Cleanroom Handling: Packaging is performed in a Class 100 clean bag, and handling should occur in a Class 1000 or cleaner environment.
- Orientation Tolerance: The crystal orientation tolerance is ±0.5–2°, which must be confirmed before application.
- Surface Quality: Surface quality is S/D 80/50 with surface roughness ≤30 nm, requiring careful handling to avoid scratches.
What are the key handling constraints for a KCl optical crystal with <110> 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 to maintain surface quality.
Can this 10 x 10 mm KCl crystal be used as a water-soluble substrate for thin-film separation?
Yes, the product description explicitly lists water-soluble thin-film substrate workflows as an application. The single-side polish and 10 x 10 mm format are suitable for film-substrate separation, leveraging KCl's solubility to release deposited films without mechanical damage.
What is the transmission range and refractive index of this KCl optical crystal?
The transmission range is 0.2–27.5 μm, covering ultraviolet to mid-infrared. The refractive index is 1.49, and the transmission is 91% across this range. These specifications make it suitable for infrared spectroscopy, prisms, lenses, and laser windows.
This 10 x 10 mm KCl optical crystal in <110> orientation with single-side polish provides broad 0.2–27.5 μm transmission at 91% and is suited to infrared spectroscopy and water-soluble thin-film substrate workflows, but its water solubility demands moisture-controlled handling and avoids chemical polishing.
Positive
- Broad UV-to-mid-infrared transmission: The crystal transmits from 0.2 μm to 27.5 μm with 91% transmission and low impurity absorption, supporting infrared spectroscopy, prisms, lenses, filters, cell windows, and laser windows.
- Water-soluble thin-film substrate capability: As a water-soluble substrate, it enables film-substrate separation workflows, allowing deposited films to be released without mechanical or chemical etching of the film itself.
Trade-offs
- Moisture-sensitive water-soluble crystal: KCl is water soluble and moisture sensitive, so it requires Class 100 clean-bag packaging and handling in a Class 1000 or cleaner environment; chemical polishing is not recommended.
- Single-side polish limits two-sided optical paths: This specific format is polished only on one side, so applications requiring transmission through two polished surfaces must use the available double-side polish option.
