The FBH405-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection in the ultraviolet spectrum. This filter, sourced from Thorlabs, is a circular bandpass filter with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.
The filter is specifically designed to transmit light in the 405 nm range, with a full width at half maximum (FWHM) of 10 nm. This means it allows a narrow band of wavelengths around 405 nm to pass through while blocking other wavelengths. The cut-on wavelength is 400 nm, and the cut-off wavelength is 410 nm, further enhancing its wavelength selectivity.
The FBH405-10 filter features a thin lens shape and is coated on both the front and back with the THo FBH405-10 coating. This coating is designed to enhance the filter's performance and durability. The filter's catalog number is FBH405-10, and it is currently in stock, according to Thorlabs' website.
