330FCS2500-MO 28 mm Dia. Mounted Colour Glass Bandpass Filter 280nm

The 330FCS2500-MO is a 28 mm diameter, mounted color glass bandpass filter, specifically designed for use at a central wavelength of 280nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is of the 'Color Glass' sub-type, which is a general category of optical filters that selectively transmit light in certain wavelength ranges while blocking other wavelengths. The 330FCS2500-MO, in particular, is designed to pass light in the 280nm range, making it suitable for applications such as ultraviolet (UV) spectroscopy, fluorescence microscopy, and other UV-based research and industrial processes.

The filter has a base shape of 'Circular', with a thickness of 3mm, providing durability and stability in its mounting. The 'Thin Lens' shape of the filter suggests that it has been designed to minimize optical aberrations, ensuring that the transmitted light is as close to the ideal as possible.

The filter's coating is another crucial aspect of its design. Both the front and back surfaces of the filter are coated with 'kni 330fcs', a coating that is specifically designed to work with this filter. The coating helps to ensure optimal performance, including high transmission in the passband and effective blocking of unwanted wavelengths.

The 'Physical Data' section of the item data provides further specifications for the filter. The 'Cut On' wavelength is 280nm, indicating the start of the passband, while the 'Cut Off' wavelength is 370nm, marking the end of the passband. This means that the filter will pass light between 280nm and 370nm, but will block light outside of this range.
