CY2408 Calcium Fluoride Crystal Substrate, CaF2

Calcium Fluoride Crystal Substrate Description

Calcium Fluoride (CaF₂) Crystal Substrates are widely employed in optics and photonics due to their excellent transmission range from the ultraviolet (UV) to the infrared (IR) region. Featuring low absorption, high laser damage threshold, and a naturally low refractive index, CaF₂ substrates eliminate the need for additional anti-reflection coatings in many applications. Their superior chemical stability and mechanical properties also render them suitable for demanding environments, including cryogenic conditions.

FAQs

Q1 Can CaF2 substrates be used for infrared (IR) applications?
Yes, CaF2 substrates are highly suitable for infrared (IR) applications. They are commonly used in IR optics, particularly for high-performance lenses and windows. CaF2 exhibits low absorption in the IR range, making it an ideal material for various IR systems.

Q2 How should Calcium Fluoride (CaF2) substrates be cleaned and maintained?
CaF2 substrates should be handled with care due to their fragility. Cleaning can be conducted using a soft, lint-free cloth and a mild detergent solution. Avoid harsh chemicals or abrasives that could damage the crystal surface. In case of heavy contamination, utilise isopropyl alcohol and ultrasonic cleaning (if applicable). Proper storage in dust-free environments is essential to maintain the quality of the substrates.

Q3. Are there any challenges with using CaF2 substrates?
While CaF2 is a commendable material for optical applications, it may present challenges in some scenarios due to its brittleness and sensitivity to high humidity. Proper handling and storage are critical to avoid surface defects and maintain optical integrity. Additionally, calcium fluoride crystals are more susceptible to scratching than some other optical materials, necessitating careful handling.
