46-443 25.4 mm Dia. Hoya RT-830 (IR) Black Colored Glass Bandpass Filter 830nm

The 46-443 is a 25.4 mm diameter circular filter from Hoya, designed for bandpass applications centered at 830nm. This filter is made of colored glass, a material identified as UVFS MAL-1965, and features a thickness of 2.5mm. The filter's coating, EDM 46-082, is applied to both the front and back surfaces, contributing to its overall performance.

The filter's geometry is defined by its diameter and thickness. With a diameter of 25.4mm, it is compatible with a wide range of optical systems. The thickness of 2.5mm, while not excessive, provides sufficient structural integrity for most applications.

The physical data of the filter includes a center wavelength (CWL) of 830nm, which is the wavelength at which the filter's transmission is maximized. This makes it suitable for applications that require narrowband filtering around this wavelength.

The filter's shape is defined as a thin lens, suggesting that it may have some degree of optical power, although this is not explicitly stated in the provided data.

The filter is available from Edmund Optics and, according to the vendor's website, is currently in stock. For more information, users are encouraged to visit the provided weblink.
