84-679 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1550nm

The 84-679 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned vendor Edmund Optics, this filter boasts a 25 mm diameter and a thickness of 3 mm, making it a versatile and robust choice for various optical systems.

This filter is specifically designed as a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths. The cut-on wavelength for this filter is 1550 nm, meaning it allows the transmission of light with wavelengths greater than or equal to 1550 nm while blocking lighter wavelengths. This feature makes it particularly useful in applications where the detection or manipulation of specific wavelength ranges is required.

The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. The front and back of the filter are coated with EDm 84-671, a coating that enhances the filter's performance and longevity. The filter's shape is that of a Thin Lens, which is designed to minimize optical aberrations and ensure optimal light transmission.

The filter's parameters, as provided by the vendor, include a catalog number (84-679) and a link to the product page on their website, ensuring easy access to additional information or purchasing options. The vendor also provides a status update, indicating that the filter is currently in stock, ensuring quick delivery for those who need it.
