65-090 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 508nm

The 65-090 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, making it an essential component in various optical systems.

The filter's primary function is to allow light transmission at a central wavelength (CWL) of 508nm, while effectively blocking light at other wavelengths. The cut-on wavelength is 503nm, and the cut-off wavelength is 513nm, indicating a narrow bandwidth of 10nm. This precise wavelength selection is crucial in applications such as fluorescence microscopy, spectroscopy, and laser technology.

The 65-090 filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-090'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in its performance.

The filter's geometry includes a thickness of 3.5 mm, which is a significant factor in determining the filter's optical performance and mechanical stability. The circular shape, a common form factor in optical components, facilitates easy integration into various optical systems.

This filter is available for purchase through the Edmund Optics website, and the current status indicates it is in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
