84-785 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 600nm

The 84-785 is a Bandpass Filter, specifically designed by Edmund Optics with a 25 mm diameter and a thickness of 3.5 mm. This filter is engineered to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it an essential component in various optical systems.

The 84-785 filter is hard coated, which enhances its durability and resistance to wear and tear, ensuring a longer lifespan and maintaining its performance over time. The coating on both the front and back surfaces of the filter is EDM 84-773, a high-quality coating known for its excellent optical properties.

The filter's central wavelength (CWL) is 600nm, and it is designed to cut on at 575nm and cut off at 625nm. This means it allows light transmission around the 600nm wavelength while blocking light at wavelengths below 575nm and above 625nm. This feature is crucial in applications where specific wavelength selection is required.

The filter is shaped as a thin lens, which is beneficial in applications where minimal thickness and weight are desirable. It is sourced from the UVFS MAL-1965 material, further enhancing its optical performance.

The 84-785 filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. This filter is a reliable and efficient solution for applications that require precise wavelength selection and high-quality optical performance.
