The 67-023 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for fluorescence applications, featuring a center wavelength of 655nm and a 40nm bandwidth.
The filter is made from UVFS MAL-1965 material, a common choice for optical applications due to its excellent transmission properties and durability. It has a thickness of 2mm, providing sufficient structural integrity for most applications.
The 67-023 filter is hard coated on both the front and back surfaces, enhancing its durability and resistance to wear and tear. The coating, identified as EDM 67-023, is specifically designed for this filter, ensuring optimal performance and longevity.
The filter's cut-on wavelength is 631.5nm, and the cut-off wavelength is 678.5nm. This means that the filter will allow light within this wavelength range to pass through while blocking out other wavelengths. This is particularly useful in fluorescence applications, where specific wavelengths need to be isolated.
The filter is shaped as a Thin Lens, allowing for easy integration into optical systems. According to the vendor's information, this filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
