35-881 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 280nm
The 35-881 is a 25 mm diameter Bandpass Filter, specifically designed for use in the ultraviolet spectrum with a center wavelength of 280nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is part of their extensive catalog of optical elements.
The filter is made from UVFS Mal-1965 material, a common choice for ultraviolet applications due to its excellent transmittance properties in this region. It has a thickness of 3.5mm, providing robustness and durability. The filter's base shape is circular, making it suitable for a wide range of optical systems.
The 35-881 features hard coating on both the front and back surfaces, denoted as 'edm 35-874'. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance. The filter's geometry, including its 25mm diameter, is designed to fit standard optical systems.
The filter's physical data includes a cut-on wavelength of 275nm and a cut-off wavelength of 285nm, with a center wavelength of 280nm. This specificity in wavelength makes it ideal for applications that require narrow-band filtering in the ultraviolet region.
