65-225 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 610nm
The 65-225 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for applications requiring a narrow bandwidth, making it ideal for tasks such as fluorescence microscopy, spectroscopy, and other precision optical systems.
The filter's primary function is to transmit light within a specific wavelength range while blocking unwanted wavelengths. The 65-225 filter is centered at 610nm, with a full width at half maximum (FWHM) of 10nm. This means it allows light transmission between 605nm and 615nm, effectively filtering out other wavelengths.
The filter is constructed with a hard-coated OD 4.0, ensuring durability and resistance to environmental factors. The thickness of the filter is 3.5 mm, which is suitable for most optical systems. The front and back surfaces of the filter are coated with the same coating, identified as 'edm 65-103', further enhancing its performance and longevity.
The filter's geometry is defined by its circular shape and a diameter of 50 mm. This size is commonly used in various optical applications, providing a good balance between light gathering capability and compactness.
