680DIB25 25 mm Dia. Standard Interference Bandpass Filter 680nm
The 680DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 680nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The 680DIB25 is cut on at 675nm and cut off at 685nm, providing a narrow band of transmission around the central wavelength. This makes it ideal for applications that require precise wavelength selection.
The filter is made from UVFS Mal- 1965, a material known for its optical properties. It has a circular base shape and a thickness of 6.1mm, which is suitable for most optical systems. The coating on both the front and back surfaces is KNI 680DIB, which contributes to the filter's performance.
The 680DIB25 has a shape described as a Thin Lens, suggesting it may have lens-like properties. However, this should be confirmed with the vendor or in the product specifications.
