65-680 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 415nm

The 65-680 is a 25 mm diameter Bandpass Interference Filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in optical systems where precise wavelength selection is required. The filter features a center wavelength (CWL) of 415nm, making it suitable for applications that demand narrowband transmission within the specified range.

The filter is constructed with a circular geometry, boasting a diameter of 25mm and a thickness of 7.5mm. This robust construction ensures durability and stability within optical systems. The filter's edges are cut at 410nm and 420nm, providing a sharp transition between the passband and the blocked wavelengths.

The 65-680 filter is coated with a traditional coating on both the front and back surfaces. This coating, identified as EDM 65-620, is designed to enhance the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides excellent environmental stability, ensuring the filter maintains its performance characteristics over time.

The filter is mounted in a Thin Lens shape, which is a common configuration for integrating filters into optical systems. This mounting style ensures easy integration and alignment within the system.
