62-986 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 650nm

The 62-986 is a high-performance longpass filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from Edmund Optics. This filter is designed for use in applications where a sharp cut-on wavelength is required, specifically at 650nm. The filter features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear.

The 62-986 filter is a circular component with a thin lens shape, making it suitable for use in a wide range of optical systems. It is designed to transmit light with wavelengths above the cut-on point (650nm) while blocking or attenuating light with wavelengths below this point. This makes it an ideal choice for applications such as fluorescence microscopy, where it can be used to block excitation light and transmit only the emitted fluorescence.

The filter is part of the UVFS MAL-1965 material family, which is known for its excellent optical properties. The cut-on wavelength is precisely controlled, ensuring consistent performance across different units. The filter is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
