84-680 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1600nm
The 84-680 is a Longpass Filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from Edmund Optics. This filter is designed for use with wavelengths of 588 nm and features a traditional coating on both the front and back surfaces. The coating material is UVFS Mal-1965, which is specifically designed for optical applications.
The Longpass Filter is designed to transmit wavelengths above a specified cut-on value, in this case, 1600 nm. This makes it ideal for applications where longer wavelengths need to be isolated or emphasized. The filter's thin lens shape allows for easy integration into optical systems.
The filter's physical data includes a cut-on wavelength of 1600 nm, indicating that it begins to transmit light at this wavelength and above. The cut-off wavelength is 0 nm, meaning it transmits all wavelengths below this value.
The filter's geometry includes a diameter of 25 mm and a thickness of 3 mm, making it suitable for use in compact optical systems. The catalog number for this filter is 84-680, and it can be found on the Edmund Optics website, where it is currently in stock.
