Calcium Fluoride (CaF2) Lenses
Broad Transmission Range: CaF2 lenses provide excellent transmission from deep UV (0.25μm) to MWIR (7μm), making them versatile for various optical applications.
Low Chromatic Dispersion: Their low chromatic dispersion ensures minimal distortion and high-quality imaging, essential for spectroscopic and imaging systems.
High Damage Threshold: CaF2 lenses can withstand high-intensity laser beams, making them ideal for excimer lasers and other high-power applications.
Low Absorption: Low absorption rates contribute to high efficiency and reduced thermal effects in laser systems.
Group Velocity Dispersion: The lowest GVD among IR materials makes CaF2 lenses suitable for femtosecond IR lasers, ensuring minimal pulse broadening.
Chemical Inertness and Mechanical Strength: CaF2 lenses are chemically inert and possess excellent mechanical strength, ensuring durability and longevity in harsh environments.
Applications: Spectroscopy, MWIR thermal imaging, excimer lasers, femtosecond IR lasers.
