320FCS2500-MO 28 mm Dia. Mounted Colour Glass Bandpass Filter 245nm

The 320FCS2500-MO is a 28 mm diameter, mounted color glass bandpass filter, specifically designed for use at a central wavelength of 245nm. 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 characterized by its ability to selectively transmit light within a specific wavelength range while blocking unwanted wavelengths. This particular filter has a cut-on wavelength of 245nm and a cut-off wavelength of 390nm, making it ideal for applications that require narrowband transmission in the ultraviolet region of the spectrum.

The filter is constructed from UVFS MAL-1965, a material known for its excellent optical properties in the UV region. It has a thickness of 3mm, providing sufficient mechanical strength while minimizing optical distortions. The filter's geometry is defined by its 28mm diameter, which is large enough to accommodate most optical systems while maintaining a compact footprint.

The 320FCS2500-MO features a 'Thin Lens' shape, which is beneficial in applications where minimal optical path length deviation is required. The filter is coated on both the front and back surfaces with KNI 320fcs, a proprietary coating developed by Knight Optical to enhance the filter's performance and durability.
