360FCS2500 25 mm Dia. Colour Glass Bandpass Filter 360nm
The 360FCS2500 is a 25 mm diameter Color Glass Filter, specifically designed for use in systems that require a bandpass filter centered at 360nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a base shape of a Circular Thin Lens, with a diameter of 25mm and a thickness of 3mm, making it suitable for a wide range of optical applications.
The 360FCS2500 features a cut-on wavelength of 330nm and a cut-off wavelength of 380nm, providing a narrow bandpass around the 360nm region. This is particularly useful in applications where precise wavelength selection is required, such as in fluorescence microscopy or UV spectroscopy.
The filter is coated on both the front and back surfaces with KNI 360FCS, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflections and increasing transmission in the passband.
