FB1490-12 Dia:1 in Bandpass Filter; CWL=1490 +-2nm; FWHM=12 +-2.4nm
The FB1490-12 is a high-quality Bandpass Filter, meticulously crafted by Thorlabs. This filter is designed with a circular base shape, making it compatible with a wide range of optical systems. The filter boasts a diameter of 25.4 millimeters and a thickness of 3.5 millimeters, ensuring durability and stability in its operation.
The FB1490-12 is constructed using soda lime ru clear material, a choice that enhances its optical performance. The filter's central wavelength (CWL) is precisely set at 1490 nanometers, with a full width at half maximum (FWHM) of 12 +-2.4 nanometers. This specificity in wavelength allows for precise light filtering, making it an ideal component for various optical applications.
The filter's coating is another notable feature. Both the front and back surfaces are coated with tho fb1490-12, a coating that further enhances the filter's performance and longevity. The filter's shape is that of a Thin Lens, a design that minimizes optical aberrations and maximizes light transmission.
The FB1490-12 is currently in stock and available for immediate purchase through Thorlabs' official website. Its catalog number is FB1490-12, and it can be found at https://www.thorlabs.com/thorproduct.cfm?partnumber=FB1490-12.
