This KBr optical crystal is moisture-sensitive and water-soluble, requiring careful handling to prevent surface degradation. It must be stored in a dry environment and handled in a cleanroom to avoid contamination.
- Moisture Sensitivity: KBr is hygroscopic and water-soluble; exposure to ambient humidity can cause surface degradation and opacity.
- Chemical Polishing Restriction: Chemical polishing is not recommended as it can damage the crystal surface; only mechanical polishing methods should be used.
- Cleanroom Handling Requirement: The crystal is packaged in a Class 100 clean bag and must be opened and handled in a Class 1000 or cleaner environment.
- Orientation Tolerance: Verify the <100> orientation within ±0.5-2° tolerance before use to ensure alignment with experimental requirements.
- Surface Quality Protection: The polished surface has a scratch/dig specification of 80/50 and roughness ≤30 nm; avoid any contact with abrasive materials.
What is the transmission range and refractive index of the KBr <100> double-side polished 20×20 mm crystal?
This KBr optical crystal transmits from 0.2 to 27.5 μm with a refractive index of 1.49 and a transmission of 91%. The <100> orientation, double-side polish, and 20 x 20 mm format are optimized for infrared spectroscopy and thin-film substrate workflows.
Can this water-soluble KBr crystal be used as a substrate for film-substrate separation, and what handling precautions are required?
Yes, the water-soluble nature of KBr enables film-substrate separation applications, but the crystal is moisture sensitive and 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.
What are the orientation tolerance and surface quality specifications for this KBr crystal?
The orientation tolerance is ±0.5–2°, surface quality is S/D 80/50, and surface roughness is ≤ 30 nm. Thickness is customizable from 0.5 to 5 mm, and the crystal is grown by the Czochralski pulling method with a cubic structure and lattice constant a = 6.291 Å.
This potassium bromide optical crystal offers broad UV-to-mid-IR transmission (0.2–27.5 μm) with high transmission (91%) and low impurity absorption, making it suitable for infrared spectroscopy and optical components. However, its water solubility and moisture sensitivity require careful handling and environmental control, and chemical polishing is not recommended.
Positive
- Broad UV-to-mid-IR transmission: Transmits from 0.2 to 27.5 μm, covering ultraviolet to mid-infrared, enabling infrared spectroscopy and optical component applications.
- Water-soluble substrate for film separation: Can be used as a water-soluble substrate for thin-film deposition and subsequent film-substrate separation, enabling unique fabrication workflows.
Trade-offs
- Moisture-sensitive crystal: The crystal is water-soluble and moisture-sensitive, requiring storage in a dry environment and careful handling to avoid surface degradation.
- No chemical polishing: Chemical polishing is not recommended for this material, limiting surface rework options and requiring careful initial finishing.
