905FIR25 25 mm Dia. Broadband Interference Bandpass Filter 905nm

The 905FIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to operate at a central wavelength of 905nm. This filter is sourced from Knight Optical, a reputable 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 out unwanted wavelengths. The 905FIR25 is cut on at 882.5nm and cut off at 927.5nm, ensuring a tight bandpass around the central wavelength. This makes it ideal for applications that require narrow-band filtering, such as laser systems or spectroscopy.

The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thin lens shape, making it suitable for use in various optical systems. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a good balance between compactness and robustness.

The 905FIR25 is coated on both the front and back with KNI 905DIR, a coating specifically designed for this filter. This coating enhances the filter's performance, ensuring high transmission and low reflection within the passband.

The filter is currently in stock and available for purchase. For more information, please refer to the vendor's website using the provided weblink.
