400FIB50 50 mm Dia. Standard Interference Bandpass Filter 400nm

The 400FIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to pass waves within the 400nm wavelength range. Sourced from Knight Optical, a reputable vendor in the optical industry, this filter is a crucial component for various optical applications.

This filter is identified by its catalog number, 400FIB50, and is available for purchase through the vendor's website, with a current status indicating it is in stock. The filter is a Bandpass Filter, a type that allows only a specific range of wavelengths to pass through while blocking others, making it ideal for applications requiring narrow-band transmission.

The filter is circular in shape, designed to fit into circular optical systems. It is made from UVFS Mal- 1965, a material specifically chosen for its optical properties. The filter has a diameter of 50mm and a thickness of 6.1mm, making it suitable for systems requiring a substantial optical path length.

The 400FIB50 has a cut-on wavelength of 395nm and a cut-off wavelength of 405nm, ensuring a tight control over the passed wavelengths. The central wavelength (CWL) is 400nm, indicating the peak transmission wavelength.

The filter's coating, KNI 400DIB, is applied to both the front and back surfaces, enhancing its performance and durability. The filter's shape is that of a Thin Lens, ensuring minimal distortion and optimal performance in its intended application.
