This KBr optical crystal is highly moisture-sensitive and water-soluble, requiring storage in a dry, low-humidity environment. Chemical polishing must be avoided to prevent surface degradation.

  • Moisture Sensitivity: Store the crystal in a desiccated environment or dry box to prevent moisture absorption and surface damage.
  • Water Solubility: Avoid contact with water or aqueous solutions, as the crystal will dissolve upon exposure.
  • Chemical Polishing Restriction: Do not use chemical polishing methods; only mechanical polishing is recommended.
  • Packaging Requirement: Handle and store the crystal in a Class 100 clean bag within a Class 1000 or cleaner environment.

What are the key performance trade-offs of using a single-side polished KBr <111> crystal for infrared spectroscopy compared to double-side polished options?

The single-side polish on this 10 x 10 mm KBr <111> crystal provides a cost-effective surface finish suitable for transmission measurements where only one optical surface requires high quality. However, double-side polishing would be necessary for applications requiring minimal scattering from both surfaces, such as laser windows or precision interferometry. The source specifies that both single-side and double-side polishing options are available, but this product is configured with single-side polish only.

Can this KBr crystal be used as a water-soluble substrate for thin-film deposition, and what handling precautions are required?

Yes, this KBr crystal is explicitly designed for water-soluble thin-film substrate workflows, enabling film-substrate separation by dissolving the crystal in water. However, the source warns that KBr is moisture sensitive and chemical polishing is not recommended. The crystal must be stored and handled in a dry environment; it is packaged in a Class 100 clean bag and processed in a Class 1000 or cleaner room to prevent moisture damage.

What infrastructure or environmental controls are necessary to maintain the optical quality of this KBr crystal during storage and use?

Because KBr is a water-soluble and moisture-sensitive crystal, storage in a low-humidity environment (e.g., desiccator or dry box) is essential to prevent surface degradation and fogging. The source notes that chemical polishing is not recommended, so any cleaning must use dry methods or anhydrous solvents. The crystal is supplied in a Class 100 clean bag from a Class 1000 or cleaner room, indicating that particulate contamination must also be minimized during handling.

This KBr optical crystal with <111> orientation and single-side polish offers broad transmission from 0.2 to 27.5 μm, making it suitable for infrared spectroscopy, optics, and water-soluble thin-film substrate workflows. Its water solubility and moisture sensitivity demand careful handling and storage, and chemical polishing is not recommended.

Positive

  • Broad UV-to-MIR transmission: Transmission range from 0.2 to 27.5 μm with 91% transmission enables use in infrared spectroscopy, prisms, lenses, and laser windows.
  • Water-soluble substrate capability: The crystal's water solubility facilitates film-substrate separation workflows, a key advantage for thin-film processing.

Trade-offs

  • Moisture and humidity sensitivity: The crystal is water-soluble and moisture-sensitive, requiring storage in dry conditions and careful handling to avoid surface degradation.
  • Chemical polishing not recommended: Chemical polishing is advised against due to solubility, limiting surface finishing options and requiring alternative mechanical polishing methods.
