67-836 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9 mm 660nm
The 67-836 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 25 mm diameter and 5.9 mm thickness, making it suitable for a wide range of applications. The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths.
The 67-836 filter is centered at 660nm, with a full width at half maximum (FWHM) of 10nm. This means it allows light between 655nm and 665nm to pass through, making it ideal for applications that require a narrow band of light. The filter's coating, EDM 67-769, is applied to both the front and back surfaces, enhancing its performance and durability.
The filter's geometry is defined by its diameter and thickness. With a diameter of 25mm, it can be used in various systems that require a larger aperture. The thickness of 5.9mm ensures the filter's structural integrity and minimizes potential distortions.
The physical data of the filter includes the cut-on wavelength at 655nm and the cut-off wavelength at 665nm. These values define the range of wavelengths that the filter allows to pass through. The central wavelength (CWL) of the filter is 660nm, which is the wavelength at which the filter's transmission is maximum.
