377FDC25 25 mm Dia. Bandpass Dichroic Filter 377nm
The 377FDC25 is a Dichroic Filter with a circular shape and a diameter of 25 mm. This filter is sourced from Knight Optical, a reputable vendor known for its high-quality optical elements. The filter is made of n-BK7 Schott material, a popular choice for its excellent optical properties and durability.
The filter's primary function is to pass wavelengths around 377nm while blocking others. The cut-on wavelength is 351nm, and the cut-off wavelength is 403nm, providing a narrow bandwidth for specific applications. This makes the 377FDC25 ideal for use in systems where precise wavelength selection is required.
The filter's coating, kni 377fdc-0, is applied to both the front and back surfaces, enhancing its performance and durability. The filter has a thickness of 1.1mm, which is considered thin in the context of optical elements, making it suitable for use in compact systems.
The 377FDC25 is currently in stock and available for immediate purchase from Knight Optical's website. The provided weblink leads directly to the product page for easy access and ordering.
