700DIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 700nm

Knight Optical's 700DIR12 is a 12.5 mm diameter Broadband Interference Bandpass Filter, specifically designed for a central wavelength of 700nm. This filter is a part of Knight Optical's extensive catalog, known for its high-quality optical elements sourced from various vendors worldwide.

The filter is of the Bandpass type, which means it allows a range of wavelengths to pass through while blocking others. In this case, the 700DIR12 is designed to pass wavelengths between 680nm and 720nm, making it ideal for applications that require narrow-band light in the red spectrum.

The filter is made from UVFS Mal- 1965, a material known for its optical properties. It has a circular base shape and a thin lens design, making it suitable for a wide range of optical systems. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, providing a balance between compactness and durability.

The 700DIR12 features a coating on both the front and back surfaces, identified as KNI 700DIR. This coating is designed to enhance the filter's performance, ensuring optimal transmission and blocking of unwanted wavelengths.
