65-132 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 400nm

The 65-132 is a Bandpass Filter, specifically designed with a 25 mm diameter and a thickness of 3.5 mm. This filter is sourced from the reputable vendor, Edmund Optics, and is part of their extensive catalog of optical elements. The Bandpass Filter is a crucial component in various optical systems, as it allows the transmission of light within a specific range of wavelengths while blocking other wavelengths.

The 65-132 filter is designed to pass light in the 400nm range, making it ideal for applications that require the transmission of blue light. The filter's cut-on wavelength is 395nm, and the cut-off wavelength is 405nm, ensuring a narrow bandwidth of 10nm. This precise wavelength selection is essential in many applications, such as fluorescence microscopy, spectroscopy, and laser technology.

The filter is hard coated, which enhances its durability and resistance to wear and tear. This coating is applied to both the front and back surfaces of the filter, providing comprehensive protection. The coating type is EDM 65-071, which is a high-quality coating known for its excellent optical properties.

The filter's geometry is defined by its diameter and thickness. With a diameter of 25mm, it provides a generous aperture for light transmission. The thickness of 3.5mm ensures structural rigidity and minimizes the risk of deformation.

The filter's shape is defined as a Thin Lens, which is a type of optical element that focuses or disperses light. This shape enhances the filter's functionality and compatibility with various optical systems.
