66-067 50.8 x 50.8 mm Hoya R-66 Red Longpass Color Glass Filter 660nm

The 66-067 Hoya R-66 Red Longpass Color Glass Filter is a rectangular filter with dimensions of 50.8 x 50.8 mm, designed for use in optical systems where longpass filtering is required. This filter is sourced from Edmund Optics and is available for purchase through their website.

The filter is made from UVFS Mal-1965 material, a type of color glass that is well-suited for longpass applications. It has a cut-on wavelength of 660nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths of light below 660nm.

The filter has a thickness of 2.5mm, providing sufficient structural integrity for most applications. It features thin lens geometry, which helps to minimize optical aberrations and distortions. The front and back surfaces of the filter are coated with EDM 66-045, a coating that enhances the filter's performance and durability.

This filter is available in stock and can be ordered directly from the Edmund Optics website. The provided weblink is valid and directs to the product page, where more information about the filter, including its specifications and pricing, can be found.
