442 US LPF-25 25 mm Dia. Mounted Ultra-Steep Longpass Filter; t=3mm 442nm
The 442 US LPF-25 is a Longpass Filter, specifically designed for use in optical systems that require precise wavelength control. This filter, sourced from Iridian Spectral Technologies, is characterized by its circular shape with a diameter of 25 mm and a thickness of 3 mm. The filter features a cut-on wavelength of 442 nm, meaning it allows transmission of wavelengths greater than 442 nm while blocking shorter wavelengths. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths shorter than the cut-on wavelength.
The 442 US LPF-25 filter is coated with IRR 442-US-LPF on both the front and back surfaces, ensuring consistent performance and protection for the filter. Its physical data, including the cut-on wavelength and diameter, are based on the UVFS MAL-1965 material ID. The filter's geometry and physical data make it suitable for a wide range of applications, particularly in systems where precise wavelength control and blocking are essential.
