65-709 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 610nm

The 65-709 is a 25 mm diameter mounted bandpass interference filter, with a thickness of 7.5 mm, specifically designed for use at a central wavelength of 610nm. This filter is sourced from the reputable vendor, Edmund Optics, and is readily available for purchase from their website.

The filter is characterized by its bandpass properties, which allow it to transmit light within a specific range of wavelengths while blocking out unwanted light from other regions of the spectrum. This is particularly useful in applications where it is necessary to isolate specific wavelengths for analysis or processing.

The 65-709 filter features a cut-on wavelength of 605nm and a cut-off wavelength of 615nm, indicating a narrow transmission band. This makes it ideal for use in situations where a high degree of wavelength specificity is required. The filter's coating, denoted as EDM 65-649 on both the front and back surfaces, further enhances its performance by reducing reflections and improving transmission efficiency.

The filter is designed in a thin lens shape, which not only contributes to its compact size but also makes it suitable for use in a wide range of optical systems. Its 25 mm diameter provides a generous aperture, allowing for high light throughput and making it suitable for use in systems with moderate to high light levels.
