660DIB25 25 mm Dia. Standard Interference Bandpass Filter 660nm
The 660DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to isolate the 660nm wavelength. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows light within a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the 660DIB25 is designed to pass light between 655nm and 665nm, making 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 thin lens design, making it suitable for a wide range of optical systems. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a balance between compactness and durability.
The 660DIB25 features a KNI 660DIB coating on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission in the passband. The filter is currently in stock and available for immediate purchase through the vendor's website.
