The ST6520 Separation Filter is a high-performance optical component designed for applications that require precise separation of light into its spectral components. This filter is made of fused silica, a material known for its excellent optical properties, including low absorption and high transmission over a wide spectral range.
The ST6520 Filter features a 652.0 nm long-pass cutoff wavelength, allowing it to pass light with wavelengths longer than 652.0 nm while blocking shorter wavelengths. This makes it an ideal choice for applications that require the isolation of infrared light, such as infrared imaging, spectroscopy, and laser applications.
The filter has a high transmission efficiency, ensuring that the maximum amount of desired light is passed through, while the high rejection ratio ensures that unwanted light is effectively blocked. The filter also has a low optical loss, ensuring that the light passing through the filter maintains its intensity and does not degrade over time.
The ST6520 Filter is available in various sizes and shapes, including circular, square, and rectangular, to fit a wide range of optical systems. It is also available with anti-reflection coating to reduce reflection losses and ensure maximum transmission efficiency.
The filter is made using state-of-the-art fabrication techniques, ensuring high precision and uniformity. It is also designed to withstand harsh environmental conditions, including high temperatures and humidity, making it suitable for use in a variety of industrial and scientific applications.
In summary, the ST6520 Separation Filter is a high-quality, high-performance optical component that is ideal for applications requiring infrared light separation. Its excellent optical properties, high transmission efficiency, and low optical loss make it a reliable and cost-effective solution for a wide range of applications.
