620DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 620nm
The 620DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 620nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the 620DIB12 is designed to allow light between 615nm and 625nm to pass through, making it ideal for applications that require a narrow band of red light.
The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It has a Thin Lens shape, which is beneficial for applications that require a compact, lightweight optical component. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for use in a variety of optical systems.
The 620DIB12 features a KNI 620DIB coating on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission in the desired wavelength range.
