The 87-804 is a Bandpass Filter, specifically designed with a 50 mm diameter and a thickness of 3.5 mm. This filter, offered by Edmund Optics, is a crucial component for applications requiring precise wavelength selection.
The filter's primary function is to allow light within a specific range of wavelengths to pass through while blocking out other wavelengths. The 87-804 is designed to pass wavelengths around 675nm, with a Cut-On wavelength of 662.5nm and a Cut-Off wavelength of 687.5nm. This makes it ideal for applications where a narrow band of light needs to be isolated.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The front and back surfaces of the filter are coated with EDM 87-780, a hard coating that enhances the filter's durability and resistance to wear and tear.
The 87-804 filter is designed in a Thin Lens shape, which is often used in optical systems to minimize aberrations and distortions. This shape also allows for easy integration into existing optical systems.
The filter is currently in stock and available for purchase through the Edmund Optics website. For more detailed information, including technical specifications and performance data, please refer to the provided weblink.
