11-982 25 mm Dia. First Surface UV Bandpass Filter; t=1.5 mm 214nm
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.
According to the vendor's website, the filter is currently in stock, ensuring quick delivery for your optical needs. For more information, you can visit the product page at https://www.edmundoptics.com/p/214nm-10nm-fwhm-25mm-dia-first-surface-uv-bandpass-filter/40724/.
