495FDC50 50 x 50 mm Bandpass Dichroic Filter 495nm
The 495FDC50 is a high-quality Dichroic Filter, measuring 50 x 50 mm, designed for use in optical systems that require precise wavelength control. This filter, sourced from Knight Optical, is a Bandpass type, specifically designed to transmit light within the 495nm wavelength range while blocking light at other wavelengths.
The filter is made from N-BK7 Schott, a widely used optical glass due to its excellent optical properties and durability. It has a thickness of 1.1mm, providing robustness and stability in its mounting and operation. The rectangular shape of the filter allows for easy integration into various optical systems.
The 495FDC50 features a cut-on wavelength of 465nm and a cut-off wavelength of 525nm. This means it starts transmitting light at 465nm and stops transmitting at 525nm, effectively filtering out any light outside this range. This characteristic makes it ideal for applications that require narrowband wavelength selection.
The filter is coated with KNI 495fdc-0 on both the front and back surfaces. This coating enhances its performance, ensuring high transmission efficiency and low reflectivity within the specified wavelength range. The coating also provides excellent environmental stability, ensuring the filter maintains its performance over time.
