550DIR25 25 mm Dia. Broadband Interference Bandpass Filter 550nm

The 550DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to center at 550nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical components.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the 550DIR25 is designed to allow transmission of light between 530nm and 570nm, making it ideal for applications that require narrow-band light in the green spectrum.

The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It has a circular base shape, a common design choice for filters due to its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortions.

The 550DIR25 features a Thin Lens shape, which is beneficial for applications where minimal thickness is required. The front and back of the filter are coated with KNI 550DIR, a coating specifically designed to enhance the filter's performance.

The physical data of the filter includes a cut-on wavelength of 530nm and a cut-off wavelength of 570nm, with a central wavelength (CWL) of 550nm. This information is crucial for designers and engineers looking to incorporate this filter into their optical systems.

According to the vendor, the filter is currently in stock and the associated web link provided is valid. This means that the filter is readily available for purchase and immediate use.
