Review EDMUND OPTICS Calcium Fluoride 75mm Uncoated Optical Window
Edmund Optics 87-705 Calcium Fluoride Optical Window - Uncoated, 75mm Diameter, 250nm-7um Wavelength Range
The Edmund Optics 87-705 Calcium Fluoride (CaF2) Optical Window is a high-quality, uncoated optical component designed for applications that require exceptional transmission in the ultraviolet (UV) and visible (VIS) spectral regions. This window features a 75mm diameter, making it suitable for a wide range of optical setups.
The 87-705 optical window is crafted from 99.99% pure calcium fluoride, a material renowned for its superior optical properties. It exhibits an extremely low dispersion, low absorption, and a high refractive index, making it an ideal choice for applications demanding exceptional clarity and color fidelity.
The wavelength range of this optical window spans from 250nm to 7um, catering to a broad spectrum of UV and VIS light. This makes it an excellent choice for applications such as spectroscopy, laser systems, and UV imaging.
Being uncoated, the 87-705 optical window allows for the highest possible transmission in its specified wavelength range. However, it is essential to note that uncoated windows may exhibit higher reflectivity, which could affect the overall performance of your optical system.
Manufactured by Edmund Optics, a globally recognized leader in optical technology, this calcium fluoride optical window promises consistent quality, precision, and durability. It is suitable for use in various environmental conditions, thanks to its solid construction and resistance to heat, cold, and humidity.
In conclusion, the Edmund Optics 87-705 Calcium Fluoride Optical Window is an exceptional choice for applications requiring exceptional transmission in the UV and VIS spectrum. Its large 75mm diameter, broad wavelength range, and high-quality construction make it a versatile and reliable component in your optical system.
Analysis of Purchasing a 75mm Uncoated Calcium Fluoride (CAF2) Optical Window (Edmund Optics 87-705)
Pros:1. High Transmission: Calcium Fluoride (CAF2) has a wide transmission range, making it suitable for use in the ultraviolet to near-infrared spectrum.
2. Low Absorption: CAF2 has minimal absorption in the UV region, which makes it ideal for applications requiring high transparency in this spectrum.
3. Low Dispersion: CAF2 has a low refractive index and low dispersion, which reduces chromatic aberration in optical systems.
4. Hardness: CAF2 is a hard material, making it resistant to scratches and physical damage, and it can withstand high temperatures.
5. Large Diameter: The 75mm diameter of this particular window provides a larger light-gathering area, which can be beneficial in some applications.
6. Uncoated: An uncoated window can exhibit lower reflectivity, especially in the UV region, which may be beneficial for certain applications.
Cons:1. High Cost: Uncoated CAF2 windows can be more expensive compared to coated windows or other materials.
2. No Anti-Reflective Coating: The lack of an anti-reflective coating can lead to higher reflectivity, potentially reducing the amount of light transmitted through the window.
3. Sensitivity to Humidity: Calcium Fluoride is hygroscopic, meaning it can absorb moisture from the air. This can lead to changes in the optical properties of the material over time.
4. Fragile: Although CAF2 is hard, it can be brittle and prone to cracking if mishandled or subjected to sudden temperature changes.
5. Limited Coating Options: If you later decide to apply a coating, the options for CAF2 are more limited compared to other materials.
Conclusion: The 75mm uncoated Calcium Fluoride optical window from Edmund Optics (87-705) offers several advantages, including high transmission, low dispersion, and resistance to physical damage. However, its high cost, lack of an anti-reflective coating, sensitivity to humidity, and brittleness are important considerations.
Recommendation: If you require a wide transmission range, low dispersion, and can handle the potential drawbacks, this window could be a good choice. However, if cost is a concern or you need improved light transmission, you may want to consider coated options or other materials. It's also crucial to handle the window carefully to avoid damage due to its brittleness.
