65-080 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 455nm
The 65-080 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable vendor Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths, centered around 455nm, while blocking other wavelengths. This makes it an ideal component for applications that require narrow-band light, such as fluorescence microscopy or laser spectroscopy.
The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-080'. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most applications.
The physical data of the filter is also noteworthy. It has a cut-on wavelength of 450nm and a cut-off wavelength of 460nm, meaning it begins transmitting light at 450nm and stops transmitting at 460nm. The central wavelength (CWL) of the filter is 455nm, indicating the peak of its transmission curve.
The filter's geometry is another crucial aspect. With a diameter of 12.5 mm, it provides a generous aperture for light to pass through. This, coupled with its thin lens shape, ensures efficient light transmission and minimal optical aberrations.
