35-888 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 280nm

The 35-888 is a 50 mm diameter Bandpass Filter, specifically designed for use in the ultraviolet (UV) spectrum at 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 UV 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 35-888 features hard coating on both the front and back surfaces, denoted as 'edm 35-874'. This coating enhances the filter's durability, making it resistant to scratches and other forms of damage, thereby extending its lifespan.

The filter's physical data includes a cut-on wavelength of 275nm and a cut-off wavelength of 285nm, with a central wavelength of 280nm. This means it allows light within this narrow band to pass through while blocking out other wavelengths, making it ideal for applications requiring precise wavelength selection.

The filter's geometry is defined by its 50mm diameter, providing a large aperture for efficient light collection. The shape of the filter is thin lens, which is beneficial for applications where minimal optical path deviation is required.
