64-631 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 775nm

The 64-631 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter is a high-quality optical component designed for use in a variety of applications. Sourced from the renowned vendor Edmund Optics, this filter boasts a catalog number of 64-631 and is available for purchase through their official website.

This filter is a Longpass type, which means it allows light of longer wavelengths to pass through while blocking shorter wavelengths. The cut-on wavelength for this filter is 775nm, ensuring that only light with a wavelength of 775nm or greater will be transmitted. The cut-off wavelength, on the other hand, is 0nm, indicating that no light with a wavelength shorter than 775nm will be allowed to pass.

The filter is circular in shape, with a diameter of 25mm and a thickness of 3mm. This makes it compatible with a wide range of optical systems and setups. The material ID for this filter is UVFS Mal-1965, providing a unique identifier for its specific composition and properties.

The coating on both the front and back of this filter is EDM 64-623. This coating is designed to enhance the filter's performance and durability, ensuring that it provides accurate and reliable results even under heavy use.

The filter's geometry is that of a Thin Lens, which means it has been designed to minimize optical aberrations and distortions. This makes it ideal for use in precision optical systems where clarity and accuracy are paramount.

In terms of availability, the 64-631 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter is currently in stock, according to the vendor's website. This means that users can purchase and receive this filter in a timely manner, ensuring that their optical projects are not delayed.
