670DIJ12 12.5 mm Dia. Standard Interference Bandpass Filter 670nm

The 670DIJ12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 670nm. 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 other wavelengths. In this case, the cut-on wavelength is 665nm, and the cut-off wavelength is 675nm, ensuring a tight bandpass around the central wavelength. The central wavelength (CWL) of the filter is 670nm, providing a high transmission rate within this range.

The filter is made from UVFS Mal- 1965, a material known for its optical properties and durability. It has a circular base shape, a common design for ease of integration into various optical systems. The geometry of the filter includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for applications requiring a compact yet robust optical component.

The coating on both the front and back surfaces of the filter is KNI 670DIJ, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, providing a high transmission rate and excellent blocking characteristics.

The filter's shape is classified as a Thin Lens, indicating that it can focus light to a point, adding to its versatility in various optical applications. The filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
