830DIR25 25 mm Dia. Broadband Interference Bandpass Filter 830nm

The 830DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to center at 830nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical components.

The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the 830DIR25 has a cut-on wavelength of 810nm and a cut-off wavelength of 850nm, making it ideal for applications that require narrow-band light transmission around the 830nm region.

The filter is made from UVFS MAL-1965, a material known for its optical properties in the ultraviolet, visible, and shortwave infrared regions. The filter has a circular base shape, a common design for optical components due to its ease of integration into various systems.

The 830DIR25 has a thickness of 6.1mm, providing sufficient structural integrity for handling and installation. The front and back of the filter are coated with KNI 830DIR, a coating that enhances the filter's performance and durability.

The filter's geometry is that of a Thin Lens, which suggests that it may have some light-focusing properties. However, this should be confirmed with the vendor or through independent testing.

According to the vendor's information, the filter is currently in stock and available for immediate shipping. The filter's web link is valid, leading to a detailed product page on Knight Optical's website.
