This potassium bromide optical crystal is water-soluble and highly moisture sensitive, requiring storage in a dry environment. Chemical polishing is not recommended due to the risk of surface degradation.
- Moisture Sensitivity: Store the crystal in a low-humidity environment to prevent moisture absorption and surface damage.
- Water Solubility: Avoid any contact with water or aqueous solutions as the crystal is water-soluble.
- Chemical Polishing Restriction: Do not perform chemical polishing on this crystal as it may cause irreversible surface damage.
- Orientation Tolerance: The crystal orientation tolerance is ±0.5–2°, which must be considered for alignment-sensitive applications.
- Surface Quality Requirement: The surface quality specification is S/D 80/50 with roughness ≤30 nm, requiring careful handling to avoid scratches.
What are the key handling constraints for this single-side polished KBr <110> crystal due to its water solubility?
This KBr optical crystal is water-soluble and moisture-sensitive, so chemical polishing is not recommended. The product is packaged in a Class 100 clean bag and must be handled in a Class 1000 or cleaner-room environment to prevent surface degradation. These constraints directly impact storage, cleaning, and integration workflows for infrared spectroscopy or thin-film substrate applications.
Does this 10 x 10 mm KBr crystal with <110> orientation support transmission across both UV and mid-IR ranges for spectroscopy?
Yes, the transmission range is 0.2–27.5 μm, covering ultraviolet to mid-infrared wavelengths, with a transmission of 91% and a refractive index of 1.49. The <110> orientation and single-side polish are specifically suited for infrared spectroscopy, prisms, lenses, and cell windows, though the 10 x 10 mm size may limit certain beam-path configurations.
What are the orientation tolerance and surface quality specifications for this KBr optical 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. These parameters are critical for ensuring consistent optical performance in laser windows or thin-film substrate separation workflows where precise crystal alignment and low scatter are required.
Potassium Bromide (KBr) optical crystal with <110> orientation, single-side polish, and 10×10 mm format offers broad transmission from 0.2 to 27.5 μm covering UV to mid-IR, with high 91% transmission and low impurity absorption, making it suitable for infrared spectroscopy and water-soluble thin-film substrate applications. Its water solubility and moisture sensitivity require careful handling and storage in dry environments, and chemical polishing is not recommended, posing operational constraints.
Positive
- Broad UV-to-mid-IR transmission: Transmission range of 0.2–27.5 μm enables use across ultraviolet to mid-infrared wavelength regions, supporting infrared spectroscopy, prisms, lenses, and laser windows.
- High transmission with low impurity absorption: 91% transmission with low impurity absorption provides efficient optical throughput, reducing signal loss in spectroscopic and optical component applications.
Trade-offs
- Moisture-sensitive water-soluble crystal: KBr is water-soluble and hygroscopic; exposure to ambient humidity can degrade surface quality, requiring storage in dry environments and handling with care to avoid dissolution.
- Chemical polishing not recommended: Due to water solubility, chemical polishing techniques are unsuitable; surface finishing must rely on mechanical methods, and orientation tolerance of ±0.5–2° must be confirmed before processing.
