FB700-40 Dia:1 in Bandpass Filter; CWL=700 +-8nm; FWHM=40 +-8nm
The FB700-40 is a Bandpass Filter, part of the extensive catalog of optical elements offered by Thorlabs. This particular filter is designed with a circular base shape, made from soda lime ru clear material, and has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm.
The FB700-40 is specifically designed to transmit light in the wavelength range of 700 nm, with a Full Width at Half Maximum (FWHM) of 40 nm, providing a narrow band of transmitted light. The filter's Cut-On wavelength is 680 nm, and the Cut-Off wavelength is 720 nm, ensuring a tight control over the spectral range of the transmitted light.
The filter's coating, applied to both the front and back surfaces, is designated as 'tho fb700-40'. This coating is designed to enhance the filter's performance, providing a high transmission rate within the specified wavelength range and a sharp cut-off on either side of this range.
The FB700-40 is available directly from Thorlabs, and the provided weblink indicates that it is currently in stock. This filter is a reliable choice for applications that require a narrow bandpass filter centered at 700 nm.
