MF469-35 25 mm Dia. GFP Excitation Filter; CWL=469nm; BW=35nm
The MF469-35 is a 25 mm diameter Bandpass Filter, specifically designed for GFP (Green Fluorescent Protein) Excitation. This filter, manufactured by Thorlabs, is a crucial component in various optical systems, particularly in fluorescence microscopy and other biomedical applications.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out other wavelengths. The MF469-35 is designed to pass light with a Central Wavelength (CWL) of 469nm and a Bandwidth (BW) of 35nm. This means it allows light between 451.5nm and 486.5nm to pass through, making it ideal for GFP excitation.
The filter is made from UVFS (Ultraviolet Fused Silica), a material known for its high transmittance in the UV, visible, and near-IR regions. The filter has a thickness of 5mm, providing durability and stability in optical systems.
The coating on both the front and back surfaces of the filter is 'tho mf469-35'. This coating enhances the filter's performance by reducing surface reflections and increasing transmission. The filter's shape is Thin Lens, which is designed to minimize optical aberrations.
According to the vendor's information, the filter is currently in stock, and you can find more details about it on the Thorlabs website using the provided weblink.
