Technical Applications & Industrial Use Cases
Due to their wide transmission window, low refractive index dispersion, and high resistance to laser-induced damage, CaF2 plano-convex cylindrical lenses are essential across precision optical systems:
- Laser Line Generation: Used to shape point laser sources into uniform line beams for machine vision, laser scanning, and material processing.
- Anamorphic Beam Shaping: Deployed in optical systems to correct astigmatism or adjust the aspect ratio of diode laser outputs.
- Thermal Imaging & Spectroscopy: Utilized in multi-spectral optical assemblies, FTIR spectrometers, and infrared detectors operating in the 3 to 5 micrometer infrared band.
Key Specifications & Performance Advantages
- Material: High-purity Calcium Fluoride (CaF2) single crystal optimized for broad-band transmission.
- Design Wavelength: Calibrated for precision performance at 587.6 nm with strict focal length tolerance.
- Surface Quality: High-precision 60-40 scratch-dig with tight centration tolerance (< 3 arcmin) and protective chamfers.
- Coating Options: Available uncoated or featuring specialized low-absorption infrared anti-reflective (IR1) coatings (average reflectance < 1.5% across 3 to 5 micrometers) to maximize throughput.
