MF475-35 25 mm Dia. FITC Excitation Filter; CWL=475nm; BW=35nm

The MF475-35 is a Bandpass Filter with a circular base shape, designed and manufactured by Thorlabs. This filter is specifically engineered for use in optical systems that require precise wavelength selection, in this case, centered at 475 nanometers with a bandwidth of 35 nanometers.

The filter has a diameter of 25 millimeters and a thickness of 5 millimeters, making it compatible with a wide range of optical systems. The physical data of the filter indicates a cut-on wavelength of 457.5 nanometers and a cut-off wavelength of 492.5 nanometers, ensuring efficient blocking of unwanted wavelengths.

The MF475-35 filter features a coating on both the front and back surfaces, identified as 'tho mf475-35'. This coating is designed to enhance the filter's performance and durability. The filter's shape is described as 'Thin Lens', suggesting that it may have lens-like properties, although this is not explicitly stated in the provided data.

According to the vendor's information, the filter is currently in stock and available for immediate purchase. The catalog number for this item is MF475-35, and more information can be found on Thorlabs' official website.
