The 11-982 is a 25 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use with a central wavelength of 214nm. This filter, offered by Edmund Optics, is a Bandpass Filter, a type of optical filter that only allows a specific range of wavelengths to pass through while blocking others.
The filter's geometry includes a diameter of 25 mm and a thickness of 1.5 mm, making it suitable for various optical applications. The physical data of this filter is equally impressive, with a cut-on wavelength of 209nm and a cut-off wavelength of 219nm, ensuring a tight control over the spectral range.
The 11-982 filter features a UVFS MAL-1965 material ID, which is a common choice for UV applications due to its high transmittance in the UV region. The filter is coated on both the front and back surfaces with the EDM 11-982 coating, enhancing its performance and durability.
This filter is designed in the shape of a Thin Lens, which is a lens with a very small focal length compared to its diameter. This design allows for a wide range of applications, making the 11-982 a versatile choice for many optical systems.
