87-867 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1375nm

The 87-867 is a Bandpass Filter, specifically designed for use in optical systems where precise wavelength selection is required. This filter, offered by Edmund Optics, has a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.

The filter is hard coated with a coating ID of UVFS Mal-1965, ensuring durability and longevity. The front and back of the filter are coated with EDm 87-854, providing consistent performance across the entire filter surface.

The Bandpass Filter is designed to transmit light within a specific range of wavelengths, while blocking light outside of this range. The 87-867 filter has a Cut-On wavelength of 1350 nm and a Cut-Off wavelength of 1400 nm, with a Central Wavelength (CWL) of 1375 nm. This makes it ideal for applications that require the transmission of light in the near-infrared spectrum.

The filter is designed in the shape of a Thin Lens, allowing for easy integration into optical systems. The catalog number for this filter is 87-867, and it is currently in stock, according to the vendor's website. For more information, users can visit the provided weblink.
