65-198 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 430nm

The 65-198 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 passband, 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 light outside this range. The 65-198 is centered at 430nm, with a full width at half maximum (FWHM) of 10nm. This means it allows light transmission between 425nm and 435nm, effectively isolating the desired wavelength from other spectral components.

The filter is constructed with a hard-coated optical substrate, denoted as UVFS MAL-1965, which has a thickness of 3.5mm. This robust coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.

The 65-198's coating on both the front and back surfaces is EDMD 65-076. This coating is designed to reduce surface reflections, thereby improving transmission and minimizing unwanted back reflections.

In terms of geometry, the filter has a circular shape, which is a common form factor in optical components due to its ease of integration into various systems. The circular shape also facilitates uniform illumination and transmission, which is crucial in many optical applications.
