FB1400-12 Dia:1 in Bandpass Filter; CWL=1400 +-2nm; FWHM=12 +-2.4nm
The FB1400-12 is a Bandpass Filter, part of Thorlabs' extensive catalog of optical elements. This filter is designed with a center wavelength (CWL) of 1400 nanometers, providing a narrow passband with a full width at half maximum (FWHM) of 12 nanometers, plus or minus 2.4 nanometers.
The filter is circular in shape, with a diameter of 1 inch (25.4 millimeters) and a thickness of 3.5 millimeters. It is made from soda lime ru clear material, a common choice for its high transmittance and durability.
The FB1400-12 filter is coated on both the front and back with Thorlabs' proprietary coating, denoted as 'tho fb1400-12'. This coating enhances the filter's performance, ensuring a high level of transmission within the passband and a sharp cut-on and cut-off.
The filter's geometry is that of a thin lens, suggesting it may have additional lens-like properties beyond its filtering capabilities. This could make it a versatile choice for a variety of optical applications.
According to Thorlabs' website, the FB1400-12 is currently in stock, making it readily available for immediate use. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
