500DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 500nm
The 500DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 500nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows a specific range of wavelengths to pass through while blocking others. In this case, the cut-on wavelength is 495nm, and the cut-off wavelength is 505nm, ensuring a tight bandpass around the central wavelength of 500nm. This makes the 500DIB12 ideal for applications that require narrow-band light, such as fluorescence microscopy or laser spectroscopy.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a thickness of 6.1mm, providing sufficient mechanical strength while maintaining high optical quality. The front and back surfaces of the filter are coated with KNI 500DIB, a coating specifically designed to enhance the filter's performance.
The 500DIB12 is shaped as a Thin Lens, which can be beneficial in certain optical systems where a lens-like element is required. This filter is currently in stock and available for immediate purchase through the vendor's website.
