66-057 25.4 mm Dia. Hoya R-72 Black Longpass Color Glass Filter 720nm

The 66-057 25.4 mm Dia. Hoya R-72 Black Longpass Color Glass Filter 720nm is a high-quality optical component designed for applications requiring longpass filtering at a cut-on wavelength of 720nm. This filter is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their website.

This circular filter, with a diameter of 25.4mm, is constructed from UVFS MAL-1965 material, a choice that ensures reliable and consistent optical performance. The filter has a thickness of 2.5mm, making it suitable for a wide range of optical systems. The R-72 designation indicates that this filter allows transmission of wavelengths longer than 720nm while blocking shorter wavelengths.

The filter's physical data includes a cut-on wavelength of 720nm and a cut-off wavelength of 0nm. This means that it begins to transmit light at 720nm and continues to do so for all longer wavelengths. The coating on both the front and back surfaces of the filter is EDM 66-046, a detail that enhances its performance and durability.

The 66-057 filter is shaped as a thin lens, a design that minimizes optical aberrations and ensures high-fidelity light transmission. According to the vendor's information, this filter is currently in stock, making it readily available for immediate use in your optical projects.
