This is a 65-112 Bandpass Filter, a high-quality optical component sourced from Edmund Optics. The filter is designed with a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for various optical applications.
The Bandpass Filter is a type of optical filter that allows light within a specific wavelength range to pass through while blocking other wavelengths. In this case, the filter is centered at 676nm, with a cut-on wavelength of 671nm and a cut-off wavelength of 681nm. This precise wavelength control makes it an ideal component for applications that require narrow-band light, such as fluorescence microscopy or laser spectroscopy.
The filter is hard coated on both sides with the EDM 65-112 coating, providing excellent durability and resistance to environmental factors. This coating also enhances the filter's performance by reducing unwanted reflections and increasing transmission.
The filter's geometry is defined by its thin lens shape, which contributes to its high performance and ease of integration into optical systems. The catalog number for this item is 65-112, and it is currently in stock, according to the vendor's website.
