Introduction to Calcium Fluoride in Optics
Calcium Fluoride (CaF₂) is a highly versatile material widely used in optical applications. Its superior transmission properties across ultraviolet (UV), visible and infrared (IR) wavelengths make it a go-to choice for precision optics. Recently, UQG Optics expanded its range of CaF₂ materials to include UV-IR, IR and Raman grades.
This expansion enables UQG to offer tailored components, including windows, plates, cover slips, and microscope slides, to meet the diverse demands of industries relying on optical clarity and durability.
Why Calcium Fluoride (CaF₂) Stands Out
Calcium Fluoride is valued for its exceptional optical clarity, low refractive index and minimal scattering. These properties make it particularly effective for optical systems operating across the UV to IR spectrum. Additionally, its durability against thermal shock and chemical wear ensures it maintains performance in harsh or demanding environments. As a result, industries such as spectroscopy, laser optics and thermal imaging have relied on CaF₂ components for decades.
Unlike alternative materials, CaF₂ can combine optical precision with robustness, which is essential for both research and applied technologies. Whether you are working with UV laser systems or developing IR imaging devices, CaF₂ provides the reliability and consistency needed to produce accurate results.
UQG Optics’ Expanded CaF₂ Range
UQG Optics now offers three primary grades of Calcium Fluoride, each designed to meet specific optical requirements:
UV-IR Grade CaF₂
The UV-IR grade provides exceptional transmission across a broad spectrum, from UV through to IR wavelengths. Its versatility makes it ideal for systems where a wide spectral range is essential. Key applications include:
- UV laser systems requiring precise beam transmission
- Spectroscopy instruments for detailed optical analysis
- Thermal imaging systems where clarity in IR wavelengths is crucial
IR Grade CaF₂
The IR grade has been optimised for infrared applications, providing unparalleled transmission in mid-to-longwave IR spectra. This grade is particularly effective for thermal systems where precision and optical efficiency are paramount. Common uses include:
- Infrared lenses used in cameras and detectors
- Thermal detectors and imaging systems
- Infrared spectroscopy for research and diagnostics
Raman Grade CaF₂
Raman-grade Calcium Fluoride is manufactured with exceptional optical purity and low scatter, qualities that are vital for Raman spectroscopy. Its ability to minimise interference ensures high-precision results in laser applications. This grade is widely used in:
- Raman spectroscopy for detailed molecular analysis
- Analytical laboratory instrumentation
- Laser systems requiring high-purity optical components
