The 36-1790-000 Coherent Calcium Fluoride Windows are a remarkable addition to any precise optical system. Crafted with meticulous attention to detail, these windows are designed to deliver exceptional optical quality and durability, making them an ideal choice for a wide range of applications.
Measuring 4mm in thickness, these windows are engineered to provide robustness and resistance to thermal shock. The primary material, calcium fluoride (CaF2), is renowned for its excellent transmittance in the infrared spectrum, extending up to 5 m, with a peak transmittance at 50.8mm. This makes these windows particularly suitable for applications that require high infrared transmission, such as laser systems, spectrometers, and astronomical observations.
With a diameter of 4mm, these windows offer a compact yet effective solution for optical systems requiring minimal space. The smooth, polished surfaces ensure minimal scattering and high light throughput, ensuring optimal performance for your system.
Each window undergoes stringent quality control procedures to ensure they meet the highest standards of precision and consistency. The 36-1790-000 Coherent Calcium Fluoride Windows are delivered with the assurance of superior quality and reliability.
In summary, the 36-1790-000 Coherent Calcium Fluoride Windows are versatile, high-performance optical components, designed to deliver exceptional optical quality and transmittance in the infrared spectrum. Whether you're working on a cutting-edge research project, developing advanced laser systems, or exploring the mysteries of the universe, these windows are an essential tool for your optical toolkit.
1. Excellent Transmission: These windows are designed for high transmission in the infrared region, making them ideal for applications requiring infrared light transmission, such as thermal imaging and laser applications.
2. Low Absorption and Scattering: Calcium fluoride has low absorption and scattering properties, which means less light is lost and the transmitted light maintains its integrity, ensuring high-quality results.
3. Good Mechanical Strength: Despite being relatively lightweight, calcium fluoride windows offer good mechanical strength, making them durable for repeated use in various applications.
4. Chemical Stability: Calcium fluoride is resistant to chemical attack, ensuring longevity and reliability in harsh environments.
Cons:1. High Cost: Coherent's calcium fluoride windows are premium products, and their high cost may be a barrier for some users, especially for large quantities or frequent replacements.
2. Fragility: While calcium fluoride is strong for its weight, it is still a brittle material and can be prone to cracking or breaking if mishandled or exposed to sudden temperature changes.
3. Limited Spectral Range: Although these windows have excellent infrared transmission, they may not be suitable for applications requiring transmission in other spectral regions (e.g., visible or ultraviolet light).
Conclusion:The 36-1790-000 Coherent Calcium Fluoride Windows are an excellent choice for applications requiring high infrared light transmission, chemical resistance, and good mechanical strength. However, their high cost, fragility, and limited spectral range are factors to consider before making a purchase. If these factors are not a concern, these windows are a reliable and high-quality choice for your infrared light transmission needs.
Recommendation:If you are looking for a cost-effective alternative with similar properties, you may want to explore other calcium fluoride window options from different manufacturers. Alternatively, consider other materials like sapphire or germanium, which may offer different spectral ranges and properties suitable for your specific application needs. Always ensure that you choose the right material for your application to ensure optimal performance and longevity.
