35-871 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 250nm

This is a 35-871 Bandpass Filter, sourced from the reputable optical components vendor, Edmund Optics. The filter has a circular shape with a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The filter is designed to pass light within a specific wavelength range while blocking other wavelengths. The passband of this filter is centered at 250nm, with a full width at half maximum (FWHM) of 10nm. This means the filter will allow light between 245nm and 255nm to pass through, making it ideal for applications that require narrow-band light filtering around the 250nm wavelength.

The filter is hard coated on both sides with the coatings "edm 35-871", which enhances its durability and performance. The hard coating also provides excellent environmental stability, ensuring the filter maintains its specified performance over time.

The filter's geometry and physical data make it compatible with various optical systems. It is designed to be used as a Thin Lens, which adds to its versatility in optical design and implementation.

The filter is currently in stock and available for purchase through the provided weblink. It is a reliable and high-performance option for applications that require narrow-band light filtering at the 250nm wavelength.
