1500DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1500nm
The 1500DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1500nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The cut-on wavelength is 1492.5nm, and the cut-off wavelength is 1507.5nm, providing a narrow bandwidth for precise optical applications.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a thickness of 6.1mm, providing sufficient structural integrity for most applications. The coating on both the front and back surfaces of the filter is KNI 1500DIB, which is specifically designed for this type of filter.
The filter's shape is that of a Thin Lens, which can be beneficial in certain optical systems where a lens effect is desired. The geometry of the filter includes a diameter of 12.5mm, making it suitable for use in systems with limited space.
According to the vendor, this item is currently in stock and the web link provided leads to its product page on Knight Optical's website. This filter is a reliable choice for applications that require a narrow bandpass filter at the 1500nm wavelength.
