87-777 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 525nm
The 87-777 is a Bandpass Filter with a diameter of 12.5 mm and a thickness of 3.5 mm, designed for use in optical systems that require a narrow band of wavelengths to pass through while blocking others. This filter is manufactured by Edmund Optics, a leading vendor in the optical industry, and is available for purchase on their official website.
The filter is hard coated, which enhances its durability and resistance to wear and tear, making it suitable for applications that require a robust and long-lasting optical component. The coating on both the front and back surfaces of the filter is EDM 87-777, which is specifically designed to optimize the filter's performance.
The 87-777 filter has a central wavelength (CWL) of 525nm, which is the wavelength at which the filter's transmission is maximum. The filter's cut-on wavelength is 512.5nm, and the cut-off wavelength is 537.5nm. This means that the filter allows wavelengths between 512.5nm and 537.5nm to pass through, while blocking wavelengths outside this range.
The filter is shaped as a thin lens, which is a type of lens with a very small thickness compared to its diameter. This shape is often used in optical systems where a thin, lightweight lens is required.
