87-792 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 675nm
The 87-792 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 25 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which is renowned for its high-quality optical properties.
The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it, while blocking other wavelengths. In this case, the 87-792 filter is designed to pass wavelengths around 675 nm, with a cut-on wavelength of 662.5 nm and a cut-off wavelength of 687.5 nm. This makes it ideal for applications that require the precise filtering of light in the near-infrared spectrum.
The filter features hard coating on both the front and back surfaces, identified as EDM 87-780. This coating enhances the durability and scratch resistance of the filter, making it suitable for use in harsh environments. The filter's thin lens shape further adds to its versatility, allowing it to be easily integrated into various optical systems.
The 87-792 filter is currently in stock and available for purchase through the Edmund Optics website. For more information, please refer to the provided weblink.
