84-072 25 mm Dia. Infrared (IR) Bandpass Filter; t=1 mm 3600nm

The 84-072 is a 25 mm diameter Infrared (IR) Bandpass Filter, with a thickness of 1 mm, manufactured by Edmund Optics. This filter is designed to transmit light in the infrared spectrum, specifically at a center wavelength of 3600nm. It features a full-width half-maximum (FWHM) of 0.14, indicating a narrow bandwidth and high spectral purity.

The filter is constructed from aluminum oxide (Al2O3), a material known for its excellent optical properties and durability. It has a circular shape, making it compatible with a wide range of optical systems. The 84-072 filter is coated on both the front and back surfaces with the EDM 84-072 coating, which enhances its performance and durability.

The physical data of the filter includes a cut-on wavelength of 3530nm and a cut-off wavelength of 3670nm. This means that it begins to transmit light at 3530nm and stops transmitting at 3670nm, effectively isolating the 3600nm wavelength. The filter's geometry includes a diameter of 25mm and a thickness of 1mm, making it suitable for use in various applications.

This filter is currently in stock and available for purchase through the Edmund Optics website. It is a valuable tool for researchers and engineers working in fields such as spectroscopy, biomedical imaging, and optical communication, where precise control over the spectral content of light is essential.
