84-741 12.5 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=2 mm 675nm

The 84-741 is a high-performance longpass filter, measuring 12.5 mm in diameter, manufactured by Edmund Optics. This filter is specifically designed for use in applications where a longpass filter is required, with a cut-on wavelength of 675 nm. The filter features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear.

The filter's geometry includes a thickness of 2 mm, and it is designed in a circular shape, making it suitable for a wide range of optical applications. The material ID for this filter is UVFS MAL-1965. The filter is designed to be thin, similar to a lens, making it easy to integrate into existing optical systems.

The physical data for this filter indicates that it is cut on at 675 nm, meaning that it begins to transmit light at this wavelength. The cut-off wavelength is 0 nm, indicating that it transmits all wavelengths of light below this point. This makes it ideal for applications where longer wavelengths need to be isolated or blocked.

The filter is available for purchase directly from the Edmund Optics website, and the link provided in the item data indicates that it is currently in stock. This ensures that users can quickly and easily acquire this filter for their optical needs.
