700DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 700nm
The 700DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 700nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted wavelengths. The cut-on wavelength is 695nm, and the cut-off wavelength is 705nm, ensuring a narrow and precise bandpass. The central wavelength (CWL) of the filter is 700nm, indicating that this is the wavelength at which the filter is most efficient.
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 700DIB, a proprietary coating developed by Knight Optical for enhanced performance.
The filter is shaped as a Thin Lens, which means it has been designed to focus light. This can be beneficial in many applications, such as imaging systems or laser applications. 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, the filter is currently in stock and can be purchased directly from their website. The weblink provided leads to the product page on Knight Optical's website, where more information and specifications can be found.
