785 US LPF-25 25 mm Dia. Mounted Ultra-Steep Longpass Filter; t=3mm 785nm
The 785 US LPF-25 is a Longpass Filter, specifically designed for use in optical systems that require a steep cut-on wavelength. This filter, sourced from Iridian Spectral Technologies, boasts a 25 mm diameter and a thickness of 3mm, making it suitable for a wide range of applications.
The filter's primary function is to allow light of longer wavelengths to pass through while blocking shorter wavelengths. In this case, the cut-on wavelength is 785nm, ensuring that only light with a wavelength of 785nm or longer will be transmitted. The cut-off wavelength is 0nm, indicating that no light with a wavelength shorter than 785nm will be transmitted.
The 785 US LPF-25 features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This makes it ideal for use in high-precision optical systems. The filter's coating, both on the front and back, is 'irr 785-us-lpf', which contributes to its high transmission efficiency and durability.
