The 34-499 is a Bandpass Filter with a circular shape and a diameter of 12.5 mm. This filter, sourced from Edmund Optics, is designed to transmit light within a specific range of wavelengths while blocking other wavelengths. The central wavelength (CWL) of this filter is 445nm, making it ideal for applications that require the use of blue light.
The filter's physical data includes a cut-on wavelength of 440nm and a cut-off wavelength of 450nm. This means that it begins to transmit light at 440nm and stops transmitting at 450nm. The thickness of the filter is 3.5 mm, providing sufficient structural integrity for most applications.
The 34-499 filter features hard coating on both the front and back surfaces. This coating enhances the filter's durability, making it resistant to scratches and other forms of damage. The coating also helps to reduce reflection, improving the filter's efficiency.
This filter is designed for use with thin lenses, making it a versatile option for a wide range of optical applications. It is currently in stock and available for purchase through the Edmund Optics website.
