88-572 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 950nm

The 88-572 is a Bandpass Filter, specifically designed for use in optical systems that require a narrow bandwidth transmission. This filter, offered by Edmund Optics, has a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.

The filter is designed to transmit light in the 950 nm region, with a cut-on wavelength of 945 nm and a cut-off wavelength of 955 nm. This precise wavelength control is achieved through the use of a Hard Coated OD 4.0 surface, which provides excellent durability and resistance to environmental factors.

The 88-572 filter features a Sub Type of Bandpass Filter, indicating its ability to transmit light within a specific range of wavelengths while blocking light outside this range. This characteristic is particularly useful in applications such as fluorescence microscopy, spectroscopy, and laser systems.

The filter's coating is another critical aspect of its design. Both the front and back surfaces are coated with EDM 88-569, a coating specifically developed to enhance the filter's performance and durability. This coating ensures optimal transmission of light in the specified wavelength range while providing protection against scratches and other forms of damage.

In terms of geometry, the filter is shaped as a Thin Lens, which is beneficial in applications where minimal optical path length distortion is required. This shape, combined with the filter's other features, makes the 88-572 an excellent choice for a variety of optical systems.
