445FCS2500-MO 28 mm Dia. Mounted Colour Glass Bandpass Filter 365nm

The 445FCS2500-MO is a 28 mm diameter, mounted color glass bandpass filter, specifically designed to pass light at a central wavelength of 365nm while blocking unwanted wavelengths. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is of the type 'Color Glass', which is a general category of optical filters that use dyed glass to block specific wavelengths. The 'Bandpass' subtype indicates that this filter allows light to pass through a specific range of wavelengths, in this case, centered around 365nm.

The filter has a base shape of 'Circular', making it suitable for applications where a circular aperture is required. The material used for this filter is UVFS Mal-1965, a type of optical glass known for its excellent transmission properties in the ultraviolet region.

The filter's geometry includes a diameter of 28mm and a thickness of 3mm, providing a robust and stable platform for optical applications. The 'cut on' wavelength is 365nm, and the 'cut off' wavelength is 480nm, indicating the range of wavelengths that the filter effectively passes. The 'cwl' or 'center wavelength' is also 365nm, representing the central point of the filter's passband.

The filter's coating is 'kni 445fcs' on both the front and back surfaces, enhancing its performance and durability. The shape of the filter is 'Thin Lens', suggesting that it may have some degree of lens-like functionality, although this is not explicitly stated in the provided data.
