This potassium chloride optical crystal is moisture-sensitive and water-soluble, requiring controlled humidity storage and handling. Chemical polishing is not recommended; only mechanical polishing methods should be used to maintain surface integrity.
- Moisture Sensitivity: Store the crystal in a low-humidity environment (e.g., desiccator or dry box) to prevent surface degradation from water absorption.
- Water Solubility: Avoid contact with water or aqueous solutions; the crystal dissolves upon exposure, compromising optical quality.
- Chemical Polishing Restriction: Do not use chemical polishing agents; the crystal reacts with many chemicals, and only mechanical polishing is permitted.
- Cleanroom Packaging Requirement: Packaging is performed in a Class 100 clean bag within a Class 1000 or cleaner environment to minimize particulate contamination.
- Orientation Tolerance: The <110> orientation is specified with a tolerance of ±0.5–2°, which must be verified before mounting in optical assemblies.
What are the key handling constraints for this KCl <110> double-side polished crystal due to its water solubility?
This KCl crystal is water-soluble and moisture-sensitive, requiring careful handling to avoid surface degradation. The product description explicitly states that chemical polishing is not recommended, and packaging is performed in a Class 100 clean bag within a Class 1000 or cleaner-room environment to maintain surface quality.
Does this 10 x 10 mm KCl crystal support thin-film substrate applications requiring film-substrate separation?
Yes, the product description lists water-soluble thin-film substrate workflows as a key application. The double-side polish and <110> orientation, combined with the crystal's water solubility, enable film-substrate separation by dissolving the KCl substrate after film deposition, leaving the film intact.
What is the specified transmission range and refractive index for this KCl optical crystal?
The transmission range is 0.2–27.5 μm, covering ultraviolet to mid-infrared, with a refractive index of 1.49 and transmission of 91%. These specifications are directly stated in the technical specifications table for the AF-KCl-110D10 model.
Atomfair AF-KCl-110D10 potassium chloride optical crystal with <110> orientation and double-side polish in a 10×10 mm format offers broadband transmission from UV to mid-IR (0.2–27.5 μm) at 91% transmission, suitable for infrared spectroscopy and thin-film substrate applications, but requires moisture-controlled handling and specification pre-confirmation due to its water solubility and custom finishing options.
Positive
- Broad UV-to-Mid-IR Transmission: Transmission range from 0.2 to 27.5 μm covers ultraviolet through mid-infrared, enabling versatile use in infrared spectroscopy, prisms, lenses, and laser windows.
- Double-Side Polish with High Transmission: Double-side polish with 91% transmission and low impurity absorption reduces scattering and improves optical performance in transmission-based applications.
Trade-offs
- Moisture Sensitivity and Water Solubility: KCl is water-soluble and moisture-sensitive; requires storage in dry conditions and careful handling to avoid surface degradation, and chemical polishing is not recommended.
- Orientation and Specification Confirmation Required: Orientation tolerance (±0.5–2°) and custom thickness (0.5–5 mm) require pre-quotation confirmation to ensure exact match to application requirements, adding a procurement step.
