810FSX20-12.5 12.5mm Dia. 810nm High-Transmitting Bandpass Filter, HBW 20nm
The 810FSX20-12.5 is a high-performance bandpass filter, designed and manufactured by Andover Corporation. This filter is specifically engineered for applications that require a narrow bandwidth and high transmission at the central wavelength.
The filter boasts a circular shape with a diameter of 12.5mm, making it suitable for a wide range of optical systems. It has a thickness of 5.9mm, providing robustness and stability in its configuration. The base material of the filter is UVFS Mal-1965, a high-quality optical material known for its excellent performance in various spectral regions.
The 810FSX20-12.5 is designed to operate at a central wavelength of 810nm, with a high transmission rate. The cut-on wavelength is 800nm, and the cut-off wavelength is 820nm, providing a narrow bandwidth of 20nm. This characteristic is crucial for applications that require precise wavelength selection and rejection of unwanted spectral regions.
The filter is coated with Andover's proprietary coatings on both the front and back surfaces. These coatings are specifically designed to enhance the performance of the filter, providing high transmission, low reflectivity, and excellent environmental stability.
The filter is available in a thin lens shape, which is beneficial for applications that require compact and lightweight optical components. The catalog number for this filter is 810FSX20-12.5, and it is currently in stock on Andover Corporation's website.
